Unpacking and Mounting the EX4500 Switch

 

Unpacking an EX4500 Switch

The EX4500 switches are shipped in a cardboard carton, secured with foam packing material. The carton has an accessory compartment and contains the quick start instructions.

Caution

EX4500 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. Open the carton.
  2. Pull out the packing material holding the switch in place.
  3. Verify the parts received against the inventory on the label attached to the carton. See Parts Inventory (Packing List) for an EX4500 Switch.
  4. Save the shipping carton and packing materials in case you need to move or ship the switch later.

Mounting an EX4500 Switch

You can mount an EX4500 switch:

  • On two posts in a 19-in. rack or cabinet by using the mounting brackets provided with the switch.

  • On four posts in a 19-in. rack or cabinet by using the separately orderable four-post rack-mount kit.

  • In a position recessed 2 in. from the front of a 19-in. rack or cabinet by using the separately orderable four-post rack-mount kit. You can mount the switch in this recessed position on four-post racks and cabinets.

The holes in the mounting brackets are placed at 1 U (1.75 in. or 4.45 cm) apart so that the switch can be mounted in any rack or cabinet that provides holes spaced at that distance.

See the Related Documentation for detailed descriptions of the various rack or cabinet mounting options.

Mounting an EX4500 Switch on Two Posts in a Rack or Cabinet

You can mount an EX4500 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 EX4500 Switch on Four Posts in a Rack or Cabinet.

Before mounting the switch on two posts in a rack:

Ensure that you have the following parts and tools available:

  • Phillips (+) screwdriver, number 2

  • 2 mounting brackets and 20 mounting screws (provided in the accessory box shipped with the switch)

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

  • Dust covers for ports

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 the rack, mount the heaviest unit at the bottom and mount the others from bottom to top in order of decreasing weight.

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 or rear of the side panels of the switch chassis depending on whether you are front-mounting or rear-mounting the switch. See Figure 1.
    Figure 1: Attaching the Mounting Bracket Along the Front of the Switch
    Attaching
the Mounting Bracket Along the Front of the Switch
  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 2.

  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.
  9. We recommend that you insert dust covers in any unused ports.

Mounting an EX4500 Switch on Four Posts in a Rack or Cabinet

You can mount an EX4500 switch on four posts of a 19-in. rack or cabinet by using the separately orderable four-post rack-mount kit. (The remainder of this topic uses “rack” to mean “rack or cabinet.”)

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 EX4500 Switch on Two Posts in a Rack or Cabinet.

Note

If you are mounting the switch on four posts, ensure that the rack is 21.5 in. through 31.5 in. deep if you will mount the switch flush with the rack front and that the rack is 23.5 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.

Before mounting the switch on four posts in a rack:

Ensure that you have the following parts and tools available:

  • Phillips (+) screwdriver, number 2

  • 12 flat-head M4x6-mm Phillips mounting screws (provided with the four-post rack-mount kit)

  • One pair of front-mounting brackets

  • One pair of rear mounting-blades

  • Screws to secure the front-mounting brackets and the rear mounting-blades to the rack (not provided)

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. Place the switch on a flat, stable surface.
  2. Align a front bracket (either flush with the front of the chassis or 2-in.-recessed from the front of the chassis) along the side panel of the switch chassis. Align the two holes in the front of the brackets with the two holes on the front of the side panel.Note

    Each side of the chassis has twelve holes for attaching the front-mounting brackets to the switch.

    Six holes on the chassis side align with six holes in the front bracket when the front bracket is mounted flush with the chassis front or recessed 2 in. from the front of the chassis.

  3. Insert M4x6-mm Phillips flat-head mounting screws into the two aligned holes and tighten the screws. Ensure that the remaining four holes in the front bracket are aligned with the four holes in the side panel. See Figure 3.
    Figure 3: Attaching the Front-Mounting Bracket to the Switch Chassis

Front-Mounting Bracket to the Switch Chassis
  4. Insert M4x6-mm Phillips flat-head mounting screws into the remaining four holes in the front bracket and tighten the screws.
  5. Repeat steps 2 through 4 for attaching the front bracket to the other side of the chassis.
  6. Have one person grasp both sides of the switch, lift the switch, and position it in the rack, aligning the front bracket holes with the threaded holes in the front post of the rack. Align the bottom hole in both the front-mounting brackets with a hole in each rack rail, making sure the chassis is level. See Figure 4.

  7. Have a second person secure the front of the switch to the rack by using the appropriate screws for your rack.
  8. Slide the rear mounting-blades into the front-mounting brackets. See Figure 5.

  9. Attach the rear mounting-blades to the rear post by using the appropriate screws for your rack. Tighten the screws.
  10. Ensure that the switch chassis is level by verifying that all the screws on the front of the rack are aligned with the screws at the back of the rack.

Mounting an EX4500 Switch in a Recessed Position in a Rack or Cabinet

You can mount an EX4500 switch in a rack or cabinet such that the switch is recessed inside the rack from the rack front by 2 inches. Use the front brackets provided in the separately orderable four-post rack-mount kit to mount the switch in a recessed position.

Reasons 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 EX4500 Switch on Four Posts in a Rack or Cabinet.

Note

You cannot mount the EX4500 switch in a recessed position in a two-post rack or cabinet.
