Installing a DECarray Cabinet
4.5 Installing the DECarray Cabinet in a Stripeset Configuration
4.5.1 Cabling the DECarray Cabinet
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 (PN BC21Q–09) from the array
DSSI I/O panel to the system I/O panel.
a. At the system I/O panel, remove the terminator or terminators. Store
these terminators in the ESD pouch on the rear door of the storage
array cabinet.
b. To determine which of the two DSSI connectors on the system I/O panel
to connect to:
• Open the system I/O panel.
• Find the KFMSA module with the lowest XMI node number in the
card cage.
• Follow the cabling from the backplane to the system I/O panel.
• While viewing the front of the I/O panel, note that the DSSI
connector on the right is KFMSA DSSI bus 1 and on the left is bus
2.
a. Connect the DSSI cable from DSSI port 1 on the DECarray I/O
panel to the DSSI bus 1 connector on the system I/O panel.
b. Connect the DSSI cable from DSSI port 2 on the I/O panel to
the DSSI bus 2 connector on the system I/O panel.
• Find the KFMSA module with the next lowest XMI node number.
Repeat step 4 except this time, connect DSSI port 3 to the DSSI
bus 1 connector and DSSI port 4 to the DSSI bus 2 connector.
