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.
Use the following procedure to install the DHU in the equipment rack:
1. The DHU is shipped with the mounting brackets installed for 19-inch rack installations.
If mounting the DHU in a 19-inch rack, proceed to step 4. If mounting the DHU in a 23-
inch rack, proceed to step 2.
2. Remove both mounting brackets from the DHU (requires TORX screwdriver with T20 bit)
3. Reinstall both mounting brackets so the long side of the bracket is flush with the DHU
front panel as shown in Figure 13. Use the screws removed in step 2 to re-attach the
brackets to the DHU enclosure.
4. Position the DHU in the designated mounting space in the rack (per system design) as
shown in Figure 14.
