Description
1
Power connection
0
This power connection requires a power cable to be attached between the
power supply and an independent electrical source capable of supporting of the
entire power load of the enclosure and controlled by its own circuit breaker.
2
Power cooling
module 0
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.
3
I/O module 0
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.
4
SAS ports
The SAS ports connect the I/O modules to the controller nodes using mini-SAS
cables.
5
I/O module 1
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 1 has a green label.
