Unpacking and Mounting the EX3400 Switch

Unpacking an EX3400 Switch

The EX3400 switches are shipped in a cardboard carton, secured with foam packing material. The carton also contains an accessory box.

CAUTION:

EX3400 switches are maximally protected inside the shipping carton. Do not unpack the switches until you are ready to begin installation.

To unpack the switch:

  1. Move the shipping carton to a staging area as close to the installation site as possible, but where you have enough room to remove the system components.
  2. Position the carton so that the arrows are pointing up.
  3. Open the top flaps on the shipping carton.
  4. Remove the accessory box and verify the contents in it against the parts inventory on the label attached to the carton.
  5. Pull out the packing material holding the switch in place.
  6. Verify the chassis components received against the packing list included with the switch. An inventory of parts provided with the switch is provided in Parts Inventory (Packing List) for an EX3400 Switch.
  7. Save the shipping carton and packing materials in case you need to move or ship the switch later.

Installing and Removing EX3400 Switch Hardware Components

The EX3400 switch chassis is a rigid sheet-metal structure that houses the hardware components. The field-replaceable units (FRUs) in EX3400 switches are:

  • Power supplies

  • Fan modules

  • Transceivers

The power supplies and fan modules are hot-removable and hot-insertable: You can remove and replace them without powering off the switch or disrupting switch functions.

See these topics for instructions for installing and removing components:

Mounting an EX3400 Switch on a Desk or Other Level Surface

Before mounting the switch on a desk or other level surface:

Ensure that you have the following parts and tools available:

  • 4 rubber feet to stabilize the chassis on a desk or other level surface (provided in the accessory box in the switch carton)

You can mount an EX3400 switch on a desk or other level surface by using the four rubber feet that are shipped with the switch. The rubber feet stabilize the chassis.

To mount a switch on a desk or other level surface:

  1. Remove the switch from the shipping carton (see Unpacking an EX3400 Switch).
  2. Turn the chassis upside down on the desk or the level surface where you intend to mount the switch.
  3. Attach the rubber feet to the bottom of the chassis, as shown in Figure 1.
  4. Turn the chassis right side up on the desk or the level surface.
  5. Ensure that the switch rests firmly on the desk or the level surface.

Before mounting the switch on two posts in a rack:

Ensure that you have the following parts and tools available:

  • Phillips (+) screwdriver, number 2 (not provided)

  • 2 mounting brackets and 8 mounting screws (provided)

  • Screws to secure the chassis to the rack (not provided)

  • 2-in.-recess front-mounting brackets (from the separately orderable four-post rack-mount kit) if you will mount the switch in a recessed position

You can mount an EX3400 switch on two posts of a 19-in. rack or cabinet by using the mounting brackets provided with the switch. (The remainder of this topic uses rack to mean rack or cabinet.)

You can mount the switch on four posts of a four-post rack by using the mounting brackets provided with the separately orderable four-post rack-mount kit. See Mounting an EX3400 Switch on Four Posts in a Rack or Cabinet.

Note:

If you need to mount the switch in a recessed position on either a two-post rack or a four-post rack, you can use the 2-in.-recess front-mounting brackets provided in the separately orderable four-post rack-mount kit.

Note:

One person must be available to lift the switch while another secures the switch to the rack.

CAUTION:

If you are mounting multiple units on a rack, mount the heaviest unit at the bottom of the rack and mount the other units from the bottom of the rack to the top in decreasing order of the weight of the units.

To mount the switch on two posts in a rack:

  1. Remove the switch from the shipping carton (see Unpacking an EX3400 Switch).
  2. Place the switch on a flat, stable surface.
  3. Align the mounting brackets along the front or rear of the side panels of the switch chassis depending on how you want to mount the switch. For example, if you want to front-mount the switch, align the brackets along the front of the chassis. See Figure 2.

    Note:

    If you need to mount the switch in a recessed position, use the 2-in.-recess front-mounting brackets from the separately orderable four-post rack-mount kit.

  4. Align the bottom holes in the mounting brackets with the holes on the side panels of the switch chassis.
  5. Insert the mounting screws into the aligned holes.
  6. Ensure that the other holes in the mounting brackets are aligned with the holes in the side panels. Insert a screw in each hole and tighten the screws.
  7. Have one person grasp both sides of the switch, lift the switch, and position it in the rack, aligning the mounting bracket holes with the threaded holes in the rack or cabinet rail. Align the bottom hole in each mounting bracket with a hole in each rack rail, making sure the chassis is level. See Figure 3.
    Figure 3: Mounting the Switch on Two Posts in a RackMounting the Switch on Two Posts in a Rack
  8. Have a second person secure the switch to the rack by using the appropriate screws. Tighten the screws.
  9. Ensure that the switch chassis is level by verifying that all screws on one side of the rack are aligned with the screws on the other side.

Mounting an EX3400 Switch in a Recessed Position in a Rack or Cabinet

You can mount an EX3400 switch in a rack or cabinet such that the switch is recessed inside the rack from the front of the rack by 2 inches. You can use the 2-in.-recess front-mounting brackets provided in the separately orderable four-post rack-mount kit to mount the switch in a recessed position.

Reasons that you might want to mount the switch in a recessed position include:

  • You are mounting the switch in a cabinet and the cabinet doors do not close completely unless the switch is recessed.

  • The switch you are mounting has transceivers installed in the uplink ports and the transceivers in the uplink ports protrude from the front of the switch.

To mount the switch in a recessed position on four posts, follow the instructions in Mounting an EX3400 Switch on Four Posts in a Rack or Cabinet. To mount the switch in a recessed position on two posts, follow the instructions in Mounting an EX3400 Switch on Two Posts in a Rack or Cabinet.

Mounting an EX3400 Switch on a Wall

Before mounting the switch on a wall:

Ensure that you have the following parts and tools available:

  • 2 wall-mounting brackets (provided in the wall-mount kit)

  • 12 wall-mounting bracket screws (provided in the wall-mount kit)

  • 6 mounting screws (8-32 x 1.25 in. or M4 x 30 mm) (not provided)

  • Hollow wall anchors rated to support up to 75 lb (34 kg) if you are not screwing the screws directly into wall studs (not provided)

  • Phillips (+) screwdriver, number 2

You can mount an EX3400 switch on a wall by using the separately orderable wall-mount kit.

To mount one or two switches on a wall:

  1. Remove the switch from the shipping carton (see Unpacking an EX3400 Switch).
  2. Attach the wall-mounting brackets to the sides of the chassis using four wall-mounting bracket screws on each side, as shown in Figure 8.
    Figure 8: Attaching Wall-Mounting Brackets to a Switch ChassisAttaching Wall-Mounting Brackets to a Switch Chassis
  3. Install six mounting screws in the wall for the wall-mounting brackets at the location shown in Figure 9:
    Note:

    Tighten the screws only part way in, leaving about 1/4 in. (6 mm) distance between the head of the screw and the wall.

    1. Drill a hole A and install a mounting screw.
    2. Drill a hole B at a distance of 5.98 in. (15.2 cm) from screw A on a level line to the right and install a mounting screw.
    3. Drill a hole C at a distance of 18.67 in. (47.43 cm) on a plumb line down from screw A and install a mounting screw.
    4. Drill a hole D at a distance of 18.67 in. (47.43 cm) on a plumb line down from screw B and install a mounting screw.
      Figure 9: Measurements for Installing Mounting ScrewsMeasurements for Installing Mounting Screws
  4. Place the switch against the wall such that the front panel of the switch faces to the right side and the holes in the mounting brackets heads align with the mounting screw heads.
  5. Slide the switch chassis to the left or right a bit so that the mounting screws are pushed into the channels of the holes in the mounting brackets until the switch rests firmly in place as shown in Figure 10.
  6. Tighten all mounting screws.
