Install a drive shelf for a hot-add
Installing a new NS224 drive shelf involves installing the shelf into a rack or cabinet,
connecting the power cords (which automatically powers on the shelf), and then setting
the shelf ID.
Before you begin
• You must have met the system requirements.
Requirements for a hot-add
• You must have completed the applicable preparation procedures.
Prepare for a hot-add
Steps
1. Install the rail mount kit that came with your shelf by using the installation flyer that came in the kit box.
Do not flange-mount the shelf.
2. Install and secure the shelf onto the support brackets and rack or cabinet by using the installation flyer.
A fully loaded NS224 shelf can weigh up to 66.78 lbs (30.29 kg) and requires two people to
lift or use of a hydraulic lift. Avoid removing shelf components (from the front or rear of the
shelf) to reduce the shelf weight, because shelf weight will become unbalanced.
3. Connect the power cords to the shelf, secure them in with the power cord retainer, and then connect the
power cords to different power sources for resiliency.
A shelf powers up when connected to a power source; it does not have power switches. When functioning
correctly, a power supply’s bicolored LED illuminates green.
4. Set the shelf ID to a number that is unique within the HA pair:

then release the button.
