The following procedure addresses two situations:
vThe entire storage subsystem has been shut down (the main circuit breakers for the rack cabinet are off).
vSome storage expansion enclosures are being
Attention:
1.Repeatedly turning the power off and on without waiting for the drives to spin down can damage the drives. Always wait at least 70 seconds after you turn off the power before you turn it on again.
2.If you are connecting a power cord to a DS3200 or storage expansion enclosure, turn off both of its power switches first. If the main circuit breaker is off, make sure that both power switches are off on each storage expansion enclosure in the rack cabinet before you turn on the main circuit breakers.
1. Are the main circuit breakers turned on?
vYes: Turn off both power switches on each enclosure that you intend to connect to the power.
vNo: Turn off both power switches on all enclosures in the storage subsystem.
2.Make sure that all power cords are connected.
Note: If the power cords are not connected, turn off both power switches on all modules in the configuration before you connect power cords or turn on the main circuit breakers.
3.If the main circuit breakers are turned off, turn them on.
Attention: You must turn on power to each attached storage expansion enclosure before you turn on power to the DS3200 so that the controllers recognize all drives in the configuration during the startup process.
4.Turn on both power switches on the rear of each storage expansion enclosure that is attached to the storage subsystem. While each storage expansion enclosure powers up, the green and amber LEDs on the front and rear of the storage expansion enclosure turn on and off intermittently. Depending on the configuration, it can take several minutes for each storage expansion enclosure to
Check the LEDs on the front and rear of all the storage expansion enclosures. Make sure that no amber LEDs are lit on any of the storage expansion enclosures.
5.Turn on both ac power switches on the rear of the storage subsystem. Figure 33 shows the locations of the ac power switches on the DS3200.
