HP Alletra 2120 Installation

Install the Expansion Shelf
Use this procedure to install and activate up to six HPE Alletra 2120 expansion shelves, depending
on the model of your array. HPE Alletra 5010H arrays can add up to four shelves.
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.
What you need for each expansion shelf:
19-inch four-post rack. The provided rails fit both round-hole and square-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.

Install the rail assemblies into the rack.
Note: To ensure that the array thumbscrews align correctly, install the rail assembly in exactly 4U of
rack space. You should insert the bottom stud on the rail kit into the bottom hole of the bottom unit
of the allotted 4U of rack space.
a) Align the bottom stud of the rail at the position you want.
b) Press the keeper latch and position the front studs in the rack. When the studs are engaged, release
the keeper latch to secure the front of the rail in the rack.
c) Align the back of the rail at the same rack position as the front.
d) Position the back studs in the rack and press the keeper latch. When the studs are engaged, release
the keeper latch to secure the back of the rail in the rack.
e) Repeat steps a through d on the other side.
The following diagram shows where the rail assemblies should be correctly installed in a rack.

Expansion Shelf Installation - HPE Alletra 2120
Connect the Power to the Expansion Shelf
Before you perform this task, you must have already installed the expansion shelf in a rack or enclosure.
1
Plug the power cables into both power supplies on the back of the expansion shelf.
2
Plug the other end of the power cables into the power circuit.
To minimize the risk of both power supplies losing power simultaneously, connect each power cable
to a different circuit.
3
Verify that the SAS LEDs are green after connecting the power cables.
4
If the expansion shelf does not come online automatically, press the power button on the front
of the chassis.
If the expansion shelf still does not turn on, contact HPE Support.

Important!
Fully configure the array before you connect and activate the expansion shelf:
Update the array to the supported operating system. HPE Alletra 5010H requires Alletra

Do not shut down the array while connecting and activating a shelf.
1
Apply power to the expansion shelf.
a) Verify that the SSDs and HDDs are installed and fully seated.
Some slots might be empty.
b) Verify that expansion shelf power is on before connecting the SAS cables.
2
Cable the expansion shelf to the SAS expansion ports on the array.
Cables install into the ports with the retention tabs down.
a) Connect the SAS Out port P1 of controller A on the array to the SAS In port of expander A on
expansion shelf 1.
b) Connect the SAS Out port P1 of controller B on the array to the SAS In port of expander B on
expansion shelf 1.
