Installation guide

The KDM70 and KDB50 adapters support RA disk drives. The KDM70
can support eight devices, with a maximum of two of these being TA tape
drives. The KDB50 supports up to four RA disks. Cabling is the same for
both adapters.
At the rear of the main cabinet:
1. Open the door.
2. For each RA or ESE20 disk, install one external SDI cable to one of the
disk controller ports (see Figure 5–3). SDI cables are packaged in the
bottom of the disk cabinet. Using a small Phillips screwdriver, install
the two screws that secure each cable to the I/O panel.
The adapters run self-test during power-up. A yellow LED on the module
lights to indicate that the module passed self-test. The system self-test
display reports the status of all controllers (see Section 7.2 and Section 7.3).
For troubleshooting information, refer to the KDM70 Controller User Guide
or the KDB50 Disk Controller User’s Guide.
