Mounting an EX 8208 Switch on a Rack or Cabinet Using a Mechanical Lift

Because of the switch's size and weight, we strongly recommend using a mechanical lift to install the switch.

Note: For instructions on installing a switch without using a mechanical lift, see Mounting an EX 8200 series Switch on a Rack or Cabinet Without Using a Mechanical Lift.

Caution: Do not install line cards in the chassis until after you mount the chassis securely on a rack or cabinet.

Caution: Before front-mounting the switch on a rack or cabinet, have a qualified technician verify that the rack or cabinet is strong enough to support the switch's weight and is adequately supported at the installation site.

Before you install the switch:

Ensure that you have the following parts and tools available to install the switch:

  • A mechanical lift
  • 24 mounting screws appropriate for your rack
  • A Phillips (+) screwdriver, number 2 or number 3, depending on the size of your rack mounting screws

Caution: If you are installing more than one switch in a rack or cabinet, install the first switch at the bottom of the rack.

To install the switch using a mechanical lift (see Figure 1):

  1. Ensure that the rack or cabinet is placed in its permanent location and is secured to the building. Ensure that the installation site allows adequate clearance for both airflow and maintenance. For details, see Clearance Requirements for Airflow and Hardware Maintenance for an EX 8208 Switch.
  2. Load the switch onto the lift, making sure it rests securely on the lift platform.

  3. Using the lift, position the switch in front of the rack or cabinet, centering it in front of the adjustable mounting brackets and/or power cord tray installed in the rack.
  4. Lift the chassis approximately 0.75 in. (1.9 cm) above the surface of the adjustable mounting brackets/power cord tray. Position the chassis in the rack as close as possible to resting on the support that the mounting brackets and/or power cord tray provide.
  5. In a four-post rack, carefully slide the switch onto the adjustable mounting brackets until the front-mounting brackets (“ears”) attached to the chassis contact the rack rails. The adjustable mounting brackets installed in the rack ensure that the holes in the front-mounting brackets align with the holes in the rack rails.

    In a two-post rack, carefully slide the switch into the rack ensuring that the front bottom of the chassis rests on the lip of the power cord tray. The front-mounting brackets (“ears”) prevent the chassis from tipping too far back.

  6. Move the lift away from the rack.
  7. In a four-post rack, slide the chassis so that the front-mounting bracket is flush with the front of the rack.

    In a two-post rack, push the bottom of the chassis so that the front-mounting bracket is flush with the front of the rack.

  8. Install a mounting screw into each of the open front-mounting holes aligned with the rack, starting from the bottom.
  9. Visually inspect the alignment of the switch. If the switch is installed properly in the rack, all the mounting screws on one side of the rack are aligned with the mounting screws on the opposite side and the switch is level.
  10. After ensuring that the switch is aligned properly, tighten the screws.
