Unpacking and Mounting the EX4200 Switch

Unpacking an EX4200 Switch

The EX4200 switch chassis is a rigid sheet-metal structure that houses the hardware components. EX4200 switches are shipped in a cardboard carton, secured with foam packing material. The carton also contains an accessory box.

CAUTION:

EX4200 switches are maximally protected inside the shipping carton. Do not unpack the switches until you are ready to begin installation.

To unpack the switch (see Figure 1):

  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 EX4200 Switch.
  7. Save the shipping carton and packing materials in case you need to move or ship the switch later.

You can mount an EX4200 switch on two posts of a 19-in. rack (either a two-post or a four-post rack) or a 19-in. 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 EX4200 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 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 switches on a rack, mount a switch in the bottom of the rack first and proceed to mount the rest of the switches from bottom to top.

To mount the switch on two posts in a rack:

  1. Place the switch on a flat, stable surface.
  2. Align the mounting brackets along the front, rear, or center 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 side panel. See Figure 3.
    Figure 3: Attaching the Mounting Bracket to the Side Panel of the SwitchAttaching the Mounting Bracket to the Side Panel of the Switch
    Note:

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

  3. Align the bottom holes in the mounting brackets with holes on the side panels of the switch chassis.
  4. Insert mounting screws into the aligned holes. Tighten the screws.
  5. 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.
  6. 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 both the mounting brackets with a hole in each rack rail, making sure the chassis is level. See Figure 4.
    Figure 4: Mounting the Switch on Two Posts in a RackMounting the Switch on Two Posts in a Rack
  7. Have a second person secure the switch to the rack by using the appropriate screws. Tighten the screws.
  8. 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.
Note:

You can mount the switch on two posts in either a two-post rack or a four-post rack by using the mounting brackets provided with the switch. See Mounting an EX4200 Switch on Two 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:

If you are mounting an EX4200 switch on four posts, ensure that the rack is 27.5 in. through 30.5 in. deep if you will mount the switch flush with the rack front and that the rack is 29.5 in. through 32.5 in. deep if you will mount the switch 2 in. recessed from the rack front, thus ensuring that the protective earthing terminal is accessible through the opening in the rear mounting-blade.

Note:

One person must be available to lift the switch while another secures it 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 four posts in a rack:

  1. Attach the front-mounting brackets (either the flush or the 2-in.-recess brackets) to the side mounting-rails using six 4-40 flat-head Phillips mounting screws. See Figure 5.

Mounting an EX4200 Switch in a Recessed Position in a Rack or Cabinet

You can mount an EX4200 switch in a rack or cabinet such that the switch is recessed inside the rack from the rack front by 2 inches. You can use the 2-in.-recess front 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 will not close completely unless the switch is recessed.

  • The switch you are mounting has an uplink module with transceivers installed in it—the transceivers in the uplink module 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 EX4200 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 EX4200 Switch on Two Posts in a Rack or Cabinet.

Mounting an EX4200 Switch on a Wall

Before mounting the switch on a wall:

Ensure that you have the following parts and tools available:

  • Phillips (+) screwdriver, number 2

  • 2 wall-mount brackets (provided with the wall-mount kit)

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

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

  • Dust covers for ports (for EX4200-24F switches only; optional)

  • Hollow wall anchors capable of supporting the combined weight of two fully loaded switches, up to 44 lb (20 kg) (not included)—if you are mounting the switch in sheetrock (wall board with a gypsum plaster core) or in wall board not backed by wall studs

Warning:

When mounted in a vertical position, an EX4200 switch must be oriented with the front panel of the chassis pointing down in order to ensure proper airflow and meet safety requirements in the event of a fire.

Note:

For easier lifting, install any additional power supplies only after you mount the switch on the wall.

You can mount an EX4200 switch on a wall by using the separately orderable wall-mount kit.

To mount the switch on a wall:

  1. Attach the wall-mount brackets to the sides of the chassis using four of the wall-mount bracket screws on each side, as shown in Figure 9.
    Figure 9: Attaching Wall-Mount Brackets to the Switch ChassisAttaching Wall-Mount Brackets to the Switch Chassis
  2. If you are mounting two switches together, line the second switch on top of the first and attach it to the mounting brackets using two wall-mount bracket screws on each side (see Figure 10).
  3. Insert the mounting screws in the wall. Insert the top pair of mounting screws 474.35 mm apart, and insert the second pair of mounting screws 151.81 mm directly below the first set.

    If the mounting screws are inserted in wall board with no stud behind it, you must use dry wall anchors rated to support 75 lb (34 kg). Insert the screws into wall studs wherever possible to provide added support for the chassis.

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

  4. Grasp each side of the switch or switches, lift the switch or switches, and hang the brackets from the mounting screws as shown in Figure 10.
    Figure 10: Mounting the Switch on a WallMounting the Switch on a Wall
  5. Tighten the mounting screws.
Note:

If it is an EX4200-24F switch, we recommend you insert dust covers in unused SFP ports.
