Installation guide

D.1 Single-System Installation of an DECarray
Make sure that the DSSI ID numbers of each TF857 magazine tape ISE
installed in the array are set to 0 and that the Tape Mass Storage Control
Protocol (TMSCP) switch is enabled (down). Refer to the TF857 magazine tape
ISE documentation for the procedure to access the DSSI adapter module.
D.1.2 Cabling the Storage Array (Single-System)
Start at the rear of the DECarray cabinet.
1. Plug the main power cable of the storage array into its power receptacle.
WARNING
Hazardous voltages are in the storage array and in the components of
the storage array.
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 (part number BC22Q–09) from
the array DSSI I/O panel to the appropriate system DSSI connector.
a. At the system DSSI connector, remove the terminator or terminators
(part number 12–29258–01). See Figure D–3. Store these terminators
in the ESD pouch on the rear door of the storage array cabinet.
b. The system DSSI connectors are (see 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.
