Installing the SF7x Storage Enclosure in a DECarray Cabinet
6.6 Cabling the SF7x in a DECarray Cabinet
Note
The following step assumes that no storage enclosures are installed
internally in the system cabinet. If there are storage enclosures
installed in the system cabinet, then one of the KFMSA modules
installed in the system XMI backplane must be connected to those
storage enclosures. Do NOT use this KFMSA module or its DSSI
connections to connect the system to the DECarray.
8. Plug the other end of the 108-inch DSSI cables into the appropriate port on
the system I/O panel at the rear of the system cabinet. To determine which
of the two DSSI connectors on the system I/O panel to connect to:
a. Locate the DSSI connectors on the system I/O panel labeled YELLOW
and GREEN.
b. For port 3 on the DECarray I/O panel, connect the 108-inch DSSI cable
to the right DSSI connector (YELLOW) of the first system I/O panel.
c. For port 4 on the DECarray I/O panel, connect the 108-inch DSSI cable
to the right DSSI connector (GREEN) of the first system I/O panel.
CAUTION
Do not apply power to the storage enclosure at this time.
Note
Perform the next step if this is the only storage enclosure to be
installed on this particular DSSI bus. If not, then proceed to the
cabling instructions for the next storage enclosure that has been
installed.
9. Install a DSSI terminator in the leftmost DSSI connector at the rear of the
SF7x storage enclosure in position 4 or 7.
10. Replace the DECarray I/O panel to its original position and secure it by
tightening the two right captive screws.
