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

  • This procedure applies to direct-attached storage only. To view instructions for switch-attached storage, view our switch-attached cabling guide.

  • 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.

      NSM100 modules

      • 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.

      NSM100B modules

      • An NS224 shelf contains two NSM100B modules. The top module goes in slot A (NSM A) and the bottom module goes in slot B (NSM B).

      • Each NSM100B module includes 2 x 100GbE CX6/DX ports: e1a and e1b.

  • 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.
