Cable The Base Enclosure To The Nvme Expansion Enclosure - Dell EMC PowerStore 500T Installation And Service Manual

Figure 14. Installing the cable management arms

Cable the base enclosure to the NVMe expansion enclosure

Prerequisites
Determine how many expansion enclosures you are installing. Use the cable label diagrams that shipped with your system to
determine the end-to-end locations for the back-end cables.
NOTE: Use QSFP28 to SFP28 cables to connect the base enclosure to the NVMe expansion enclosure. Use QSFP28 to
QFSP28 cables to connect an NVMe expansion enclosure to another NVMe expansion enclosure.
Steps
1. Apply the provided cable labels to each end of the cables.
NOTE: The system ships with three sheets of labels. All three sheets contain the same information. They are just
different colors. You only need to use one label sheet per expansion enclosure. The different colors are to identify which
expansion enclosure the cables belong to. For example, you could use the pink label sheet for the first enclosure, and
then use the green sheet for the second enclosure.
2. Ensure that the cable management arms (CMAs) are fully open and in the service position.
3. Open the CMA baskets and loosen the velcro straps.
4. Based on the following illustrations, route the data cables through the CMAs. The cables represented by yellow lines route
through the upper CMA, and the cables represented by blue lines route through the lower CMA.
Follow these guidelines when routing cables:
● Gently route the cables into and around the arms without excess bending.
● Ensure that the data cables are oriented correctly to latch into the ports.
● There should not be any more slack between the expansion enclosure and the CMA than is needed to direct the cable.
Any excess length should be outside of the CMA and dressed when cabling is complete.
● In two or three expansion enclosure configurations, route the data cables between the expansion enclosures through the
CMA for one expansion enclosure and into the CMA of the other expansion enclosure.
