Replacing a Fibre Channel Arbitrated Loop Hub
Follow these instructions to replace a
Fibre Channel Arbitrated Loop Hub (DS-DHGGA-CA)

NOTE
Before installing the replacement hub, turn OFF all ac power to the
subsystem and the server/host.

Install the Replacement Hub
Place the new hub in the same location that the failed hub had occupied. This will ensure that the existing cables will reach
all necessary system components.

Attach Data Cables
Connect all data cables to the hub. Any hub port position may be used, for either the subsystem or the server/host. Be sure to
tighten the cable connector jackscrews for all cables. The number of cables depends on your system configuration.

Power ON the HUB
Connect the ac power cord to the back of the hub and plug the other end into an ac outlet. There is no ON/OFF switch on the
hub, the hub is ON as soon as ac power is applied. You should see all hub indicator lamps illuminated. There is one green
power lamp and nine amber port lamps.

Power ON the Subsystem
Press the ac power switch to the ON position. It will begin to initialize.

Power ON the Server/Host
Press the server/host ac switch to the ON position. It will begin to initialize.

System Ready
The system is ready when the hub port lamps are extinguished at each cable connection.
