Converting a Single-System Configuration to a DSSI VAXcluster Configuration
C.2 Conversion Procedure
C.2.4 Powering Up the DECarray
Once the DECarray has been converted to the DSSI VAXcluster configuration
and is labeled, you are ready to apply power.
CAUTION
Ensure that the ac power switch on each SF7x storage enclosure and
magazine tape ISE installed is in the off position.
1. At the rear of the storage array, turn the power controller on. Ensure that
the BUS/OFF/ON switch is in the down position.
2. At the rear of the storage array, turn on each magazine tape ISE installed
(if present). Power up position 5, then 6. Observe the front panels for fault
indications.
3. At the rear of the storage array, turn on each SF7x storage enclosure
starting with position 1 and continuing in numerical order.
4. Press each drive dc power switch for each SF7x storage enclosure. Start
with position 1 and continue in numerical order.
5. Observe the OCP indicators (Figure C–10).
a. Check that the TERM PWR indicator (behind the door of the OCP) is
on for all positions installed.
b. Check that the SPLIT indicator (behind the door of the OCP) is off for
all positions.
c. Ensure that all DSSI ID switches on all OCPs are set to left-rear
(ID = 1), left-front (ID = 2), right-front (ID = 3), and right-rear (ID =
4).
6. Press the Ready button on the OCP (Figure C–10). The green Ready
indicator flickers, then lights steadily once the ISE is on-line.
