Component Description
This section provides the detailed illustration and description for each component.
System Subrack
The system subrack houses a midplane to provide reliable connections for interface modules and to distribute power and signals to inner modules.
Expansion Module
Each expansion module provides two PRI HD expansion ports and two EXP HD expansion ports. Expansion modules enable a high-density disk enclosure to communicate with a controller enclosure or another high-density disk enclosure.
Ports
Figure 4-206 shows the ports of an expansion module.
Only serial cables can be inserted into the serial port. Do not insert network cables into the serial port position.

Power Module
The storage system supports AC power modules that ensure that a high-density disk enclosure works correctly in maximum power consumption mode.
Indicator
Table 4-87 describes the indicator on a power module of a storage system that is powered on.
Fan Module
A fan module provides heat dissipation and supports the normal running of the disk enclosure in maximum power consumption mode.
Indicator
Table 4-88 describes the indicator on a fan module of a storage system that is powered-on.
