Unpacking and Mounting the EX8208 Switch

 

Unpacking an EX8200 Switch

After you prepare the installation site as described in Site Preparation Checklist for an EX8200 Switch, you may unpack the switch.

Note

The switch is maximally protected inside the shipping box. Do not unpack it until you are ready to begin installation.

Ensure that you have the following parts and tools available to unpack the EX8200 switch:

  • A 7/16-in. or 11-mm open-end or socket wrench to remove the bracket bolts from the shipping pallet

  • A box cutter or packing knife to slice open the tape that seals the top of the box

The switch ships in a cardboard box that has a two-layer wooden pallet base with foam cushioning between the layers. The switch chassis is bolted to the pallet base.

The EX8208 chassis ships with the Switch Fabric and Routing Engine (SRE) module(s), Switch Fabric (SF) module, fan tray, and power supplies for the configuration you ordered already installed. Any line cards ordered ship separately.

The EX8216 chassis ships with the Routing Engine (RE) module(s), SF modules, fan trays, and power supplies for the configuration you ordered already installed. Any line cards ordered ship separately.

See EX8208 Switch Configurations and EX8216 Switch Configurations for information about base configurations and redundant configurations.

To unpack the switch (see Figure 2 and Figure 3):

  1. Move the shipping box to a staging area as close to the installation site as possible. For an EX8208 switch, make sure there is enough space to remove components from the chassis if necessary (for example, if you do not have a mechanical lift to use when you install the switch). While the chassis is bolted to the pallet, you can use a forklift or pallet jack to move it.
  2. Position the shipping box with the arrows pointing up.
  3. Open the four pallet fasteners near the bottom of the shipping box that attach the cardboard box to the wooden pallet. To open a pallet fastener, squeeze together the two ridges (“fins”) in the depression in the latch, then slide the pallet fastener out of the cardboard box slot in which it is inserted. See Figure 1.
    Figure 1: Pallet Fastener
    Pallet Fastener
  4. Carefully slice open the tape that holds the top of the cardboard box closed and open the top of the box.
  5. Remove the cardboard accessory box from the center of the foam padding.
  6. Remove the foam padding from the top of the box.
  7. Slide the cardboard box off the pallet.
  8. Remove the plastic cover from the switch chassis.
  9. Use a 7/16-in. or 11-mm open-end or socket wrench to remove the four sets of bracket bolts that secure the chassis to the shipping pallet.
  10. Unpack the accessory box and lay out the contents so that they are ready for use.
  11. Verify that your order includes all appropriate parts. See Parts Inventory (Packing List) for an EX8208 Switch and Parts Inventory (Packing List) for an EX8216 Switch.
  12. Store the brackets and bolts inside the accessory box.
  13. Save the shipping box, pallet, and packing materials in case you need to move or ship the switch at a later time.

To connect the switch to a network for out-of-band management, follow instructions in Connect a Device to a Network for Out-of-Band Management. To connect the switch to a management console, follow instructions in Connect a Device to a Management Console Using an RJ-45 Connector.

Installing Adjustable Mounting Brackets in a Rack or Cabinet for an EX8200 Switch

To mount the switch on a four-post rack or cabinet, you must first install the adjustable mounting brackets in the rack or cabinet. (The remainder of this topic uses “rack” to mean “rack or cabinet.”) The EX8200 switch comes with a four-piece set of adjustable mounting brackets that supports the chassis in the rack.

Note

The adjustable mounting brackets are not for installation in two-post racks.

The four adjustable mounting bracket pieces are:

  • 1 left front adjustable mounting bracket. The bracket is labeled “LEFT FRONT” on the side of the bracket that faces the interior of the rack, near the holes for attaching the bracket to the rack.

  • 1 right front adjustable mounting bracket. The bracket is labeled “RIGHT FRONT” on the side of the bracket that faces the interior of the rack, near the holes for attaching the bracket to the rack.

  • 2 rear adjustable mounting brackets. These brackets are labeled “REAR” on the side of the bracket that faces the interior of the rack, near the holes for attaching the bracket to the rack. The rear brackets are interchangeable; you can use either of the rear brackets with the right or left front adjustable mounting bracket.

Ensure that you have the following parts and tools available to install the adjustable mounting brackets:

  • A Phillips (+) screwdriver, number 1, 2, or 3, depending on the size of your rack mounting screws

  • A Phillips (+) screwdriver, number 2 to install the screws that connect the rear and front mounting brackets

  • 16 mounting screws appropriate for your rack to attach the four mounting bracket pieces to the rack

When you install the adjustable mounting brackets, the “arms” of the brackets overlap. The overlap area adjusts the total bracket length to fit three standard rack sizes: 23.62 in. (600 mm), 30 in. (762 mm), and 31.5 in. (800 mm).

To install the mounting brackets in a four-post rack (see Figure 6 and Figure 7):

  1. Remove the adjustable mounting brackets from the accessory box.
  2. Decide where to position the switch in the rack. If the rack is empty, position the switch in the lowest possible location. See Rack Requirements, and Cabinet Requirements.
  3. Position the left front adjustable mounting bracket at the desired position in the left side of the rack and line up its front screw holes with the holes in the rack. Use 4 mounting screws appropriate for your rack to attach the left front bracket to the rack.
  4. Position one of the rear brackets at the left rear of the rack on the same level as the left front bracket, so that the rear bracket overlaps with the left front bracket. The screw holes for connecting the front and rear brackets should overlap. Use 4 mounting screws appropriate for your rack to attach the rear bracket to the rack.
  5. Connect left front and rear brackets (see Figure 5):
    1. Insert 6 of the screws provided with the mounting brackets into the overlapping bracket holes.
    2. Hand tighten the screws fully (to 12–16 in.-lb torque) using a number 2 Phillips screwdriver.
    Figure 5: Adjustable Mounting Brackets for Four-Post Rack Installation
    Adjustable Mounting
Brackets for Four-Post Rack Installation
  6. Position the right front adjustable mounting bracket at the desired position in the right side of the rack opposite the installed left front bracket, so that it is on the same rack level as the left bracket. If the right and left front brackets are not on the same level, the chassis will rest at an angle in the rack instead of resting flat and level. Line up the right bracket's front screw holes with the holes in the rack. Use 4 mounting screws appropriate for your rack to attach the right front bracket to the rack.
  7. Position the other rear bracket at the right rear of the rack on the same level as the right front bracket, so that the rear bracket overlaps with the right front bracket. The screw holes for connecting the front and rear brackets should overlap. Use 4 mounting screws appropriate for your rack to attach the rear bracket to the rack.
  8. Connect the right front and rear brackets (see Figure 5):
    1. Insert 6 of the screws provided with the mounting brackets into the overlapping bracket holes.
    2. Hand tighten the screws fully (to 12–16 in.-lb torque) using a number 2 Phillips screwdriver.

Installing the Power Cord Tray in a Rack or Cabinet for an EX8200 Switch

The power cord tray is supplied with all EX8200 switches. The power cord tray is optional for four-post rack or cabinet installation but mandatory for a two-post rack or cabinet installation. (The remainder of this topic uses “rack” to mean “rack or cabinet.”) To mount an EX8208 switch in a two-post rack, you must install the power cord tray in the rack before installing the switch.

Note

The EX8216 switch can be installed only in a four-post rack. Installation in a two-post rack is not supported.

The power cord tray provides support for the front of the EX8208 chassis during installation of the switch in a two-post rack. The front edge of the chassis rests on the upper edge (lip) of the power cord tray.

The power cord tray provides a place to organize and tie down the power cords for the power supplies.

The power cord tray uses 1 U of rack space, so the total space occupied by an EX8208 switch chassis and power cord tray is 15 U, and the total space occupied by an EX8216 switch chassis and power cord tray is 22 U.

Ensure that you have the following tools and parts available to install the power cord tray:

  • A Phillips (+) screwdriver, number 1, 2, or 3, depending on the size of your rack mounting screws

  • 4 mounting screws appropriate for your rack to attach the power cord tray to the rack

To install the power cord tray (see Figure 8 and Figure 9):

  1. Remove the power cord tray from the accessory box.
  2. Decide where to position the switch in the rack. If the rack is empty, choose the lowest possible location. See Rack Requirements, and Cabinet Requirements.Note

    To mount an EX8208 switch on a two-post rack, you must install the power cord tray in the rack before installing the switch. See Figure 9. Installation of an EX8216 switch in a two-post rack is not supported.

  3. Position the power cord tray in the rack space immediately below the position in which you want to install the switch (in a two-post rack) or where the switch is installed (in a four-post rack) (see Figure 8). Line up the screw holes of the power cord tray with the holes in the rack. Use 4 mounting screws appropriate for your rack to attach the power cord tray to the rack.

Mounting an EX8208 Switch on a Rack or Cabinet

The EX8208 switch ships installed with front-mounting brackets on the chassis for mounting the switch on a 19-in. equipment rack or cabinet. The switch also comes with adjustable mounting brackets to support it in the rack.

In a four-post rack, the switch consumes 14 U without the optional power cord tray and 15 U with the optional power cord tray. In a two-post rack, the power cord tray is mandatory. The switch with the power cord tray consumes 15 U. You can mount up to three switches on a 42 U four-post rack or on a 45 U two-post rack provided that the racks meet the strength requirements to support the combined weight of the switches.

Note

If you are mounting multiple switches on a rack or cabinet, mount a switch on the bottom of the rack or cabinet first and then mount the rest of the switches from bottom to top.

Warning

If you install the switch without using a mechanical lift, at least three people must be available to lift the unloaded switch chassis (all components except the backplane removed) onto the adjustable mounting brackets (in a four-post rack or cabinet) or onto the lip of the power cord tray (in a two-post rack or cabinet).

Caution

Do not install line cards in the chassis until after you mount the chassis securely on a rack or cabinet.

Before mounting an EX8208 switch on a rack or cabinet:

Ensure that you have the following parts and tools available to mount the switch on a rack or cabinet:

  • A Phillips (+) screwdriver, number 2 or number 3, depending on the size of your rack mounting screws, for mounting the switch on a rack or cabinet

  • A Phillips (+) screwdriver, number 1, to remove the power supplies from the chassis if you are mounting the switch without using a mechanical lift

  • 24 mounting screws appropriate for your rack

To mount the EX8208 switch on a rack or cabinet (see Figure 10 and Figure 11):

  1. In a four-post rack or cabinet, install the adjustable mounting brackets at the desired position (see Installing Adjustable Mounting Brackets in a Rack or Cabinet for an EX8200 Switch).

    In a two-post rack or cabinet, install the power cord tray (see Installing the Power Cord Tray in a Rack or Cabinet for an EX8200 Switch). The power cord tray is optional for four-post rack installation.

  2. Lift the chassis into the rack using a mechanical lift. For instructions on how to install the chassis using a mechanical lift, see Mounting an EX8208 Switch on a Rack or Cabinet Using a Mechanical Lift.

    In a four-post rack, place the chassis on the adjustable mounting brackets. In a two-post rack, place the front edge of the chassis on the lip of the power cord tray with at least three people supporting the rear of the chassis until you can bolt the chassis into the rack.

    If a mechanical lift is not available, remove all components and ensure that at least three people are available to lift the empty chassis into the rack. For instructions on how to install the chassis without using a mechanical lift, see Mounting an EX8208 Switch on a Rack or Cabinet Without Using a Mechanical Lift.

  3. Insert 24 mounting screws appropriate for your rack (not provided) into the aligned holes. Use the appropriate Phillips (+) screwdriver to tighten the screws to the rack or cabinet rail.

Mounting an EX8208 Switch on a Rack or Cabinet Using a Mechanical Lift

Because of the switch's size and weight, we strongly recommend using a mechanical lift to install the switch.

Note

For instructions on installing a switch without using a mechanical lift, see Mounting an EX8208 Switch on a Rack or Cabinet Without Using a Mechanical Lift.

Caution

Do not install line cards in the chassis until after you mount the chassis securely on a rack or cabinet.

Caution

Before front-mounting the switch on a rack or cabinet, have a qualified technician verify that the rack or cabinet is strong enough to support the switch's weight and is adequately supported at the installation site.

Before you install the switch:

Ensure that you have the following parts and tools available to install the switch:

  • A mechanical lift

  • 24 mounting screws appropriate for your rack

  • A Phillips (+) screwdriver, number 2 or number 3, depending on the size of your rack mounting screws

Caution

If you are installing more than one switch in a rack or cabinet, install the first switch at the bottom of the rack.

To install the switch using a mechanical lift (see Figure 12):

  1. Ensure that the rack or cabinet is placed in its permanent location and is secured to the building. Ensure that the installation site allows adequate clearance for both airflow and maintenance. For details, see Clearance Requirements for Airflow and Hardware Maintenance for an EX8208 Switch.
  2. Load the switch onto the lift, making sure it rests securely on the lift platform.
    Figure 12: Installing the EX8208 Switch Chassis Using a Mechanical Lift
    Installing the EX8208 Switch
Chassis Using a Mechanical Lift
  3. Using the lift, position the switch in front of the rack or cabinet, centering it in front of the adjustable mounting brackets and/or power cord tray installed in the rack.
  4. Lift the chassis approximately 0.75 in. (1.9 cm) above the surface of the adjustable mounting brackets/power cord tray. Position the chassis in the rack as close as possible to resting on the support that the mounting brackets and/or power cord tray provide.
  5. In a four-post rack, carefully slide the switch onto the adjustable mounting brackets until the front-mounting brackets (“ears”) attached to the chassis contact the rack rails. The adjustable mounting brackets installed in the rack ensure that the holes in the front-mounting brackets align with the holes in the rack rails.

    In a two-post rack, carefully slide the switch into the rack ensuring that the front bottom of the chassis rests on the lip of the power cord tray. The front-mounting brackets (“ears”) prevent the chassis from tipping too far back.

  6. Move the lift away from the rack.
  7. In a four-post rack, slide the chassis so that the front-mounting bracket is flush with the front of the rack.

    In a two-post rack, push the bottom of the chassis so that the front-mounting bracket is flush with the front of the rack.

  8. Install a mounting screw into each of the open front-mounting holes aligned with the rack, starting from the bottom.
  9. Visually inspect the alignment of the switch. If the switch is installed properly in the rack, all the mounting screws on one side of the rack are aligned with the mounting screws on the opposite side and the switch is level.
  10. After ensuring that the switch is aligned properly, tighten the screws.

Mounting an EX8208 Switch on a Rack or Cabinet Without Using a Mechanical Lift

If you cannot use a mechanical lift to install the switch (the preferred method), you can install it manually.

Caution

The chassis with only the backplane and no other components weighs approximately 89 lb (41 kg). Lifting the chassis and mounting it in a rack or cabinet requires at least three people.

The chassis has two handles. Do not lift a fully loaded chassis by the handles; make sure the chassis is empty (contains only the backplane) before you lift it. If two of the people lifting the chassis use the handles to lift it, the third person must lift from the rear of the chassis. The rear of the chassis is heavier than the front of the chassis, so when you lift the chassis by the handles, the chassis tips toward the heavier back end. The person lifting from the back must be aware of this behavior and must be braced to prevent the chassis from tipping over.

When lifting the chassis, do not grasp the switch by the blue panel at the top front of the chassis. Doing so can cause the panel to pop off of the switch.

Caution

Before front-mounting the switch in a rack, have a qualified technician verify that the rack is strong enough to support the switch's weight and is adequately supported at the installation site.

Before you install the switch:

  1. Prepare the site for installation as described in Site Preparation Checklist for an EX8200 Switch.
  2. Ensure the site has adequate clearance for both airflow and hardware maintenance as described in Clearance Requirements for Airflow and Hardware Maintenance for an EX8208 Switch.
  3. Unpack the switch as described in Unpacking an EX8200 Switch.
  4. Remove all components except the backplane from the chassis. See:
  5. In a two-post rack, install the power cord tray at the desired position (see Installing the Power Cord Tray in a Rack or Cabinet for an EX8200 Switch). The lip of the power cord tray will support the front of the chassis when you install the switch in the rack.

    In a four-post rack, install the adjustable mounting brackets at the desired position (see Installing Adjustable Mounting Brackets in a Rack or Cabinet for an EX8200 Switch). Optionally, you can also install the power cord tray and use it to manage the power supply cords.

  6. Review chassis lifting guidelines as described in Chassis and Component Lifting Guidelines.

Ensure that you have the following parts and tools available to install the switch:

  • 24 mounting screws appropriate for your rack

  • A Phillips (+) screwdriver, number 2 or number 3, depending on the size of your rack mounting screws

To install the switch in the rack or cabinet (see Figure 14 and Figure 15):

Caution

If you are installing more than one switch in a rack or cabinet, install the first one at the bottom of the rack. Do not attempt to install a switch manually in an upper position in a rack or cabinet.

  1. Ensure that the rack or cabinet is placed in its permanent location and is secured to the building.
  2. Position the switch in front of the rack or cabinet, centering it in front of the adjustable mounting brackets. Use a pallet jack if one is available.
  3. With one person on each side and one person in the rear, hold the bottom of the chassis and carefully lift it onto the adjustable mounting brackets installed in a four-post rack or onto the power cord tray installed in a two-post rack. See Figure 13.Warning

    To prevent injury, keep your back straight and lift with your legs, not your back. Do not twist your body as you lift. Balance the load evenly and be sure that your footing is firm.

    Figure 13: Lifting an EX8208 Switch Chassis Without Using a Mechanical Lift

Chassis Without Using a Mechanical Lift
  4. In a four-post rack, carefully slide the switch onto the adjustable mounting brackets until the front-mounting brackets attached to the chassis contact the rack rails. The adjustable mounting brackets ensure that the holes in the front-mounting brackets attached to the chassis align with the holes in the rack rails.

    In a two-post rack, carefully slide the switch over the lip of the power cord tray and into the rack. Push the bottom of the chassis so that the front-mounting bracket is flush with the front of the rack.

  5. Install a mounting screw into each of the open front-mounting holes aligned with the rack, starting from the bottom.
  6. Visually inspect the alignment of the chassis. If the chassis is installed properly in the rack, all the mounting screws on one side of the rack are aligned with the mounting screws on the opposite side and the switch is level.
  7. After ensuring that the switch is aligned properly, tighten the screws.
