Dell PowerStore Installation and Service Guide for PowerStore 1000, 1200, 3000, 3200, 5000, 5200, 7000, 9000, and 9200

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: If you are installing more than one NVMe expansion enclosure, use the 2M cables (PN 038-004-928-00) to connect the base enclosure to the NVMe expansion enclosure. Use the 2M cables (PN 038-004-928-00) to connect an NVMe expansion enclosure to another NVMe expansion enclosure with PowerStore version 3.2.0.1 or earlier. Use the 2.5M cables (PN 038-004-986-00) to connect an NVMe expansion enclosure to another NVMe expansion enclosure with PowerStore version 3.2.1 or later. Contact your service provider if you need different cable lengths.

Steps

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, but they are 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.
Ensure that the cable management arms (CMAs) are fully open and in the service position.
Open the CMA baskets and loosen the velcro straps.
Based on the following figures, 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.

Route the power cables through the CMAs. The power cables for power supplies on the left route through the upper CMA. The power cables for power supplies on the right route through the lower CMAs.
Plug each power cable into the expansion enclosure power supply and secure the cord with the retention bail at the connector.
NOTE:If the power source PDU is energized, do not connect the power cables to the PDU until the system is ready to be brought online. If you connect the power cables sooner, the system may power on during the installation.
NOTE:It is recommended that you plug in the black power cables on the left and the gray power cables on the right. The power cables work in either power supply, but a consistent cabling method makes it easier to troubleshoot issues.
Close all the baskets and tighten the Velcro on the arms to prevent the cables from slipping.
