Hard Disk Module
The Hard Disk Module contains a 6 U (267 mm) x 80 mm card with a 4 HP (20 mm),
single-wide rear panel. The module installs from the rear of the chassis and is hot-swappable.
The Hard Disk Module contains the system nonvolatile memory implemented as a hard disk.
There must be one Hard Disk Module for each Chassis Control Module. It installs opposite the
Chassis Control Module in slot 6 or 7. The Hard Disk Module is keyed so that it can be
installed only in slots 6 and 7.
The serial port COM is identical to the serial port on the Chassis Control Module and can be
used as a local management port.
The Fast Ethernet port Eth is not used.
Figure 21 on page 56 shows the Hard Disk Module rear panel.
