Cable the base enclosure to the expansion enclosure
Follow these guidelines to cable the base enclosure to an expansion enclosure.
Prerequisites
NOTE:
One cabinet requires four SAS cables, two cabinets requires six SAS cables, and three cabinets require eight SAS
cables. Verify that you have the correct amount of cables before you start.
CAUTION:
If you observe incorrect cabling between expansion enclosures or to the base enclosure, do not
attempt to correct the cable connections. To avoid a potential service disruption, gather support materials and
contact your service provider for guidance.
CAUTION:
Incorrect cabling could cause all new drives to be locked.
Apply cable labels at each end of the following cables:
● Node to first expansion enclosure
● Node to last expansion enclosure
● Expansion enclosure to expansion enclosure if you are installing more than one
Steps
1. Cable SAS port B from each node on the base enclosure to the link control card (LCC) on the first expansion enclosure in
the stack:
a. Connect node A, SAS port B to LCC A, port A on the expansion enclosure.
b. Connect node B, SAS port B to LCC B, port A on the expansion enclosure.
2. Cable SAS port A from each node on the base enclosure to the LCCs on the last expansion enclosure in the stack:
a. Connect node A, SAS port A to LCC B, port B on the last expansion enclosure.
b. Connect node B, SAS port A to LCC A, port B on the last expansion enclosure.
3. If you are installing more than one expansion enclosure, cable expansion enclosure to expansion enclosure:
a. Connect LCC A, port B on the first expansion enclosure to LCC A, port A on the next expansion enclosure.
b. Connect LCC B, port B on the first expansion enclosure to LCC B, port A on the next expansion enclosure.
