11. To connect additional PFC 500Es, attach a copper cable between the PFC 500E’s
LCC EXP connector and the next PFC500E’s PRI (primary) connector. If this
PFC500E and the next PFC500E have a second LCC, repeat this step for the
second LCC.
12. Make sure all the slots in the PFC 500 and each PFC 500E contain either CRUs or
filler modules. At least three disk modules (in slots 0, 1and 2) are required in the
PFC500.
13. In the cabinet, set the main circuit breaker switches to the on position.
The PFC 500 and any PFC500Es in the cabinet will power up.
PFC500/E powerup and initialization
The only power switches on a PFC 500/E are those on the power supply, which are
normally covered by the drive fan pack. As a result, a PFC 500/E is always active.
When ac power is initially applied to a PFC 500/E, the disk drives power up according
to their specifications, and spin up in a specified sequence. The slot spin-up delays are
multiples of 12 seconds. The maximum delay is 84 seconds. The same delays are used
when you insert a drive while a PFC500/E is powered up.
NOTE: Upon powerup, all LUNs are controlled by RAID Controller A if it is
operational. RC B controls LUNs only if RC A fails, and continues to control LUNs
until the next powerup.
PFC500/E powerdown
To turn off power correctly
1. Stop any I/O activity to the PFC 500/E.
2. Shut off power to the ac distribution strips that supply the PFC 500/E.
The power in the distribution strips may be controlled by a circuit breaker located
inside the cabinet (if the cabinet has such breakers) or may be controlled by a
circuit breaker located externally to the cabinet.
To turn on power, reverse the steps to powerup the PFC500/E.
Binding disk modules into groups
After cabling a PFC 500/E and any PFC 500Es, you must bind disk modules into LUNs
and create a file system using the Profile XP Disk Utility. Refer to the Profile XP System
Guide for more information on configuring your storage system.
