This section describes the operational features of the Compaq StorageWorks
RAID 4000.
Before applying power to the RA4000, all components of the storage system
must be installed and connected to the Storage Hub. Hard drives should be
installed in the RA4000 so that they can be identified and configured at power
up.
The StorageWorks RAID 4000 components must be powered up in the
following order:
1. Storage Hub(s)—Power is applied when the AC power cord is
plugged in.
2. RA4000(s)—Powered on with the power switch located in the upper left
corner of the front panel on tower systems or upper right on rack
systems.
3. Server(s).
The RA4000 is equipped with a series of LEDs located on strategic
components. With the exception of the LEDs located on the front panel, these
LEDs relate only to individual components.
