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:
• 19-inch four-post rack. The provided rails fit both square-hole and unthreaded round-hole racks.
Racks with a depth of 1200 mm best accommodate the length of the array chassis, providing ample space for cabling and
ease of service. Racks with a depth of 1075 mm can be used but may provide limited space for cables and component
access.
• Four rack units (4U) of space available in the 19-inch rack
• At least two SAS cables, 1 m or 3 m (two 1 m cables are included) rack
CAUTION: Start-up current draw may exceed 6A. When attaching multiple shelves, attach and activate the shelves
one at a time.
• Before beginning, download and read the Release Notes, available on HPE InfoSight (https://infosight.hpe.com). If you do
not have an HPE account, click Sign up and provide the required information.
• The power supplies are 220V AC or 110V AC auto-detecting.
• This product is intended for installation in restricted-access locations only, such as a dedicated equipment room or an
electrical closet.
