Unpacking and Mounting the EX6210 Switch

 

Unpacking an EX6200 Switch

After you prepare the installation site as described in Site Preparation Checklist for an EX6210 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 EX6200 switch:

  • A 7/16-in. or 11-mm open-end or socket wrench to remove the nuts from the bracket bolts (the side of the attached to the chassis).

  • A 10-mm open-end or socket wrench to remove the nuts from the bracket bolts (the side of the attached to 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 EX6210 chassis ships with one Switch Fabric and Routing Engine (SRE) module, fan tray, an AC or DC power supply, and two line cards for the configuration you ordered already installed. Any additional SRE modules, line cards, or power supplies ordered ship separately. See EX6210 Switch Configurations for information about different shipping configurations.

To unpack the switch (see Figure 2):

  1. Move the shipping box to a staging area as close to the installation site as possible. For the 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.

  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 (on the chassis side).
  10. Use a 10-mm open-end or socket wrench to remove the four sets of bracket bolts that secure the chassis to the shipping pallet (on the pallet side).
  11. Unpack the accessory box and lay out the contents so that they are ready for use.
  12. Verify that your order includes all appropriate parts. See Parts Inventory (Packing List) for an EX6210 Switch .
  13. Store the brackets and bolts inside the accessory box.
  14. Save the shipping box, pallet, and packing materials in case you need to move or ship the switch at a later time.

Installing Adjustable Mounting Brackets in a Rack or Cabinet for an EX6200 Switch

Note

The adjustable mounting brackets are optional for four-post rack and cabinet installations of EX6200 switches.

The adjustable mounting brackets do not ship with the EX6200 switches. You can purchase them separately.

To mount the switch on a four-post rack or cabinet, you can install the optional adjustable mounting brackets in the rack or cabinet. (The remainder of this topic uses “rack” to mean “rack or cabinet.”) The four-piece set of adjustable mounting brackets support the EX6200 chassis in a four-post 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 5):

  1. Remove the adjustable mounting brackets from the 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 4):
    1. Insert 6 of the screws provided with the mounting brackets into the overlapping bracket holes.
    2. Tighten the screws fully (to 12–16 in.-lb torque) using a number 2 Phillips screwdriver.
    Figure 4: 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 4):
    1. Insert 6 of the screws provided with the mounting brackets into the overlapping bracket holes.
    2. 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 EX6200 Switch

Note

The power cord tray is optional for four-post and two-post rack or cabinet installations of EX6200 switches.

The power cord tray does not ship with the EX6200 switches. You can purchase it separately.

The power cord tray provides a place to organize and tie down the power cords for the power supplies. It also provides support for the front of the EX6210 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 uses 1 U of rack space (the remainder of this topic uses “rack” to mean “rack or cabinet” ) , so the total space occupied by an EX6210 switch chassis and power cord tray is 15 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 6 and Figure 7):

  1. Remove the power cord tray from the shipping 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.
  3. Position the power cord tray in the rack space immediately below the position in which you want to install the switch or where the switch is installed (see Figure 6). 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.
