Use the following procedure to install the HU in the equipment rack:

1. The HU is shipped with the mounting brackets installed for 19-inch rack installations. If

mounting the HU in a 19-inch rack, proceed to

Step 4. If mounting the HU in a 23-inch

rack, proceed to Step 2.

2. Remove both mounting brackets from the HU (requires TORX screwdriver with T20 bit)

and save screws (six-screws on each side) for reuse.

3. Reinstall both mounting brackets so the short side of the bracket is flush with the HU front

panel as shown in

Figure 10. Use the screws removed in Step 2 to re-attach the brackets to

the HU chassis.

4. Position the HU in the designated mounting space in the rack (per system design plan) and

then secure (but do not tighten) the HU to the rack using the four machine screws provided

(use #12-24 or M6 x 10 screws, whichever is appropriate).

5. Locate two vertical cable guides, not provided with the HU.

Warning: Wet conditions increase the potential for receiving an electrical shock when

installing or using electrically powered equipment. To prevent electrical shock, never install or

use electrical equipment in a wet location or during a lightning storm.

Note: To insure that all optical connectors remain dust-free during installation, leave all dust

caps and dust protectors in place until directed to remove them for connection.

Note: Provide a minimum of 3 inches (76 mm) of clearance space on both the left and

right sides of the HU for air intake and exhaust.

Note: A vertical cable guide kit is available separately as an accessory.
