Unpacking and Mounting the EX4650 Switch

Unpacking the Switch

EX4650 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:

EX4650 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 marked on the carton are pointing up.
  3. Open the top flaps on the shipping carton.
  4. Pull out the packing material holding the switch in place.
  5. Verify the parts received against the inventory on the label attached to the carton.
  6. Save the shipping carton and packing materials in case you need to move or ship the switch later.

Mounting an EX4650 Switch on Four Posts of a Rack or Cabinet

Before mounting the switch on four posts of a rack:

Ensure that you have the following parts and tools available:

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

  • 6 flat-head 4-40 Phillips mounting screws (provided with the four-post rack-mount kit)

  • 12 flat-head 4x6-mm Phillips mounting screws (provided with the four-post rack-mount kit)

  • One pair each of flush or 2-in.-recess front-mounting brackets (provided with the four-post rack-mount kit)

  • One pair of side mounting-rails (provided with the four-post rack-mount kit)

  • One pair of rear mounting-blades (provided with the four-post rack-mount kit)

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

You can mount an EX4650 switch on four posts of a 19-in. rack or a 19-in. cabinet by using the separately orderable four-post rack-mount kit. (The remainder of this topic uses rack to mean rack or cabinet.)

Note:

To ensure that the protective earthing terminal is accessible through the opening in the rear mounting-blade:

  • Ensure that the rack is 27.5 in. (70 cm) through 30.5 in. (77.5 cm) deep if you are mounting the switch flush with the rack front on four posts of a rack.

  • Ensure that the rack is 29.5 in. (75 cm) through 32.5 in. (82.5 cm) deep if you are mounting the switch 2 in. recessed from the rack front.

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 of a rack:

  1. Place the switch on a flat, stable surface.
    Note:

    The four-post rack-mount kit ships with the short front-mounting brackets attached to the side mounting-rails. If you want to recess the switch in the rack, you must unscrew the short front-mounting brackets from the side mounting-rails by using the Phillips (+) screwdriver and attach the long front-mounting brackets to the side mounting-rails.

  2. Align the side mounting-rails along the side panels of the switch chassis. Align the two holes in the rear of the side mounting-rails with the two holes on the rear of the side panels.
  3. Insert 4x6-mm Phillips flat-head mounting screws into the two aligned holes and tighten the screws by using the screwdriver. Ensure that the remaining four holes in the side mounting-rails are aligned with the four holes in the side panel. See Figure 1.

  4. Insert the 4x6-mm Phillips flat-head mounting screws into the remaining four holes in the side mounting-rails and tighten the screws by using the screwdriver.
  5. Have one person grasp both sides of the switch, lift the switch, and position it in the rack, aligning the side mounting-rail 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 2.

  6. Have a second person secure the front of the switch to the rack by using the appropriate screws for your rack.
  7. Slide the rear mounting-blades into the side mounting-rails. See Figure 3.

  8. Attach the rear mounting-blades to the rear post by using the appropriate screws for your rack. Tighten the screws.
  9. 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.
Note:

We recommend that you install cover panels in the unused power supply slots.
