Install the Expansion Shelf

Use this procedure to install and activate up to six ES3 expansion shelves, depending on the model of your HPE Nimble Storage
array.
CAUTION:
When you activate the expansion shelf, there is a momentary pause in data services from the array. You might
need to activate the expansion shelf during a maintenance window.
The chassis weighs over 52 kg (115 lb). Always use at least two people or a server lift when lifting the chassis.
Before you begin
What you need for each expansion shelf:

ease of service. Racks with a depth of 1075 mm can be used but may provide limited space for cables and component
access.
