You cable each NS224 shelf you are hot-adding so that each shelf has two connections to each controller in the HA pair.

This cabling section describes how to cable the NS224 shelf to the following storage systems:

About this task

  • Familiarize yourself with proper cable connector orientation, and the location and labeling of ports on the NS224 NSM100 shelf modules.

    • Cables are inserted with the connector pull-tab facing up.

      When a cable is inserted correctly, it clicks into place.

      After you connect both ends of the cable, the shelf and controller port LNK (green) LEDs illuminate. If a port LNK LED does not illuminate, reseat the cable.

    • You can use the following illustration to help you physically identify the shelf NSM100 ports, e0a and e0b.

      An NS224 shelf contains two NSM100 modules. The top module goes in slot A (NSM A) and the bottom module goes in slot B (NSM B).

      Each NSM100 module includes 2 x 100GbE QSFP28 ports: e0a and e0b.

  • After you have cabled a hot-added shelf, ONTAP recognizes the shelf:

    • Drive ownership is assigned if automatic drive assignment is enabled.

    • NSM shelf firmware and drive firmware should be updated automatically, if needed.

      Note Firmware updates can take up to 30 minutes.
