Replacing a fiber optic cable, switch, or hub

This section details how to replace a fiber optic cable, switch, or hub.

Removing a fiber optic cable, switch, or hub

Use the following steps to remove a fiber optic cable connected to either side of

your switch or hub, or to remove the switch or hub:

1. Shut down the host system (refer to applicable host documentation for more

details).

2. Shut down the array controllers:

■ In single-controller configurations, shut down “this controller” with the

following command:

SHUTDOWN THIS_CONTROLLER

■ In dual-redundant controller configurations, shut down the “other

controller” first, and then shut down “this controller” with the following

commands:

SHUTDOWN OTHER_CONTROLLER

SHUTDOWN THIS_CONTROLLER

Note: After the array controllers shut down, the Reset buttons and the first three LEDs

turn on (see Figure 23). This can take several minutes, depending on the amount of

data that needs to be flushed from the cache modules.

Proceed only after the Reset buttons stop flashing and remain solid.
