I/O Module
The HPE 3PAR StoreServ 7000 Storage I/O modules are located at the rear of the system. I/O modules
have two Mini-SAS universal ports, which can be connected to Adapters or other ports and each port
includes External Port Activity LEDs, labeled 0–3. The I/O module also includes a Power and Fault LED.
IMPORTANT:
Notice that the I/O Modules are installed differently between the SFF Drive Enclosure and the LFF
Drive Enclosure.
• In the SFF Drive Enclosure, the I/O Modules in the enclosure are inverted 180° from each other,
as well as the SAS ports.
• In the LFF Drive Enclosure, the I/O Modules in the enclosure are installed in the same direction,
as well as the SAS ports.

Description
supply and an independent electrical source capable of supporting of the entire power
load of the enclosure and controlled by its own circuit breaker.
The Power Cooling Module (PCM) is an integrated power supply and cooling fan. One
PCM can supply enough power for the enclosure. Each PCM must draw power from
different mains. If one main fails, operation of the other PCM continues.
The I/O modules connect the Controller Nodes to the Drive Enclosures using mini-
SAS cables, enabling the transfer of data between the Controller Nodes, drives,
PCMs, and enclosures.
I/O Module 0 has a red label.
The SAS ports connect the I/O Modules to the Controller Nodes using mini-SAS
cables.
