Follow these workflow steps to hot-add your NS224 shelf.

Before you begin

To hot-add an NS224 shelf, your HA pair must meet certain requirements. Review the hot-add requirements and best practices.

OnePrepare to hot-add your shelf

Depending on your platform model, you might need to install additional RoCE-capable PCIe cards or I/O modules, configure the non-dedicated RoCE-capable Ethernet ports for storage use, recable an existing shelf across two sets of ports in different slots for resiliency against slot failure, and disable automatic drive assignment if you are manually assigning drive ownership.

TwoInstall your shelf

To install the shelf, install the rail kit for the shelf, and then install and secure your shelf in the telco rack or cabinet. Next, connect the power cords to power on the shelf and then assign a unique shelf ID to ensure the shelf is distinct within the HA pair.

ThreeCable your shelf

Cable the shelf you are hot-adding so that it has two connections to each controller in the HA pair.

FourComplete your hot-add

If you disabled automatic drive assignment as part of the preparation for the hot-add, you need to manually assign drive ownership and then reenable automatic drive assignment, if needed.
