Installing a DECarray with a VAX 4000 System
D.1 Single-System Installation of a DECarray
D.1.2 Cabling the DECarray (Single-System)
Start at the rear of the DECarray cabinet.
1. Plug the main power cable of the DECarray into its power receptacle.
WARNING
Hazardous voltages are in the DECarray and in the components of the
DECarray.
When performing any operation involving the power source, turn off
the power controls of all components and on the power controller.
Disconnect the power cable from the source outlet. Perform the
operation, then reconnect the power cable to the source.
2. Connect the 108–inch DSSI cable or cables (PN BC22Q–09) from the
DECarray DSSI I/O panel to the appropriate system DSSI connector.
a. At the system DSSI connector, remove the terminator or terminators
(PN 12–29258–01). See Figure D–3. Store these terminators in the
ESD pouch on the rear door of the DECarray cabinet.
b. The system DSSI connectors are (Figure D–3):
• DSSI Bus 0 (embedded adapter, also connects to internal TF and
RF ISEs)
• DSSI Bus 1, Model 300 only (embedded adapter, TF and RF ISEs)
• KFQSA 1 (first installed adapter in the Q-bus backplane, RF ISEs
only)
• KFQSA 2 (second installed adapter in the Q-bus backplane, RF
ISEs only)
Note
Only ports 1 through 4 are used on the DECarray in a single-system
configuration.
