At the rear, the chassis assembly contains two power and cooling modules, two I/O modules,
two 5V regulators, and two LEDs
(Figure 4)
. Refer to Section
3.1.2 "Enclosure Status LEDs"
for description of the color and status of the LEDs.

I/O Module
The two I/O modules are hot-swappable and provide a redundant path to the disks
(Figure 5)
.
Each I/O module provides five 4-wide SAS data links. These modules communicate inter-IO
information using Ethernet through the baseboard.
There are LEDs mounted on the I/O module to indicate the status of the module. Refer to
Section
3.1.4 "I/O Module LEDs"
for description of the color and status of the LEDs.
