a. Verify that all communication and power cables are plugged into the back of
the FAStT900 Storage Server and to a properly grounded ac electrical
outlet.
b. Turn on the power supply switches on the back of the FAStT900 Storage
Server (see Figure 23). You must turn on both power-supply switches to
take advantage of the redundant power supplies.
c. Use the storage-management software and the Fault indicator lights to
check the overall status of the FAStT900 Storage Server and its
components. See “Checking the indicator lights” on page 20.
4. Depending on the type of operating system on the host server, perform either a
server power cycle, a server restart, or a rescan for hardware on the host
server.
Turning off the power
Attention: The FAStT900 Storage Server is designed to run continuously, 24
hours a day. Except in an emergency, never turn off the power even if any
FAStT900 Storage Server fault indicator lights are lit. Use the proper
troubleshooting or servicing procedure to correct the fault before you turn off the
power. This measure ensures that the FAStT900 Storage Server powers up
correctly later. Also do not power off the storage server to reset it. Use the Reset
Controller menu function in the Storage Manager Client program instead.
