Installing a CX200-Series DPE2
DPE2 Powerup and Initialization
Before applying power to a storage system, make sure all the disk
module slots in each disk enclosure contain either disk or filler
modules, for proper cooling and normal operation.
Do not power up a disk enclosure without at least one SP or LCC installed.
To power up the CX200-Series system:
1. Turn on the power to any DAE2 connected to the CX200.
2. Turn the CX200/CX200LC power supply/cooling module
switches to the on (
l
) position.
3. If present (CX200 systems only), turn the SPS power switch to the
on position.
4. In the cabinet, set the main circuit breaker switches to the on
position.
The CX200/CX200LC and any connected DAE2 in the cabinet
will power up.
The only power switches on a DPE2 or DAE2 disk enclosure are those on the
power supply, which are normally on. As a result, the units are always active.
When you initially apply ac power to a disk enclosure, the disk drives
power up according to their specifications, and spin up in a specified
sequence dictated by enclosure and loop id. The slot spin-up delays
range from 0 to 84 seconds. The slots use the same delays when you
insert a drive while the system is powered up.
The CX200-Series hardware monitor (FRU monitor) resets and begins
its control loop. The port bypass circuits enter the states indicated by
their associated drives. The monitor continues to run in this local
mode until it receives commands that dictate otherwise. In local
mode, the monitor maintains the port bypass circuits in the same
states as the drive command signals. When a drive fault occurs, the
corresponding drive fault light turns on. Firmware commands can
take control of the port bypass circuits and the drive status lights.
