3Connect the Inner Rail to the UNS
4Connect the Outer Rail to the Rack
5Insert the UNS into the Rack
1.2.1 Prepare the Installation Requirements
• A rack with 2U space.
• Two sliding rails.
• 10 M6 screws for attaching both outer rails to the rack.
• The rack depth can be from 71.12 cm to 91.44 cm (28 to 36 inches).
Note: Failure to use the proper screws may damage the unit.
1.2.1.1 Precautions
• Make sure the rack will safely support the combined weight of all the equipment it contains. The
weight of the UNS with 12 hard drives installed is about 22.8 KG. The maximum load the rails can
hold is 33.56 Kg.

• Make sure the position of the UNS does not make the rack unstable or top-heavy. Take all
necessary precautions to anchor the rack securely before installing the unit.
1.2.2 Separate the Slide Rails
A slide rail consists of an inner rail and an outer rail. Release the lock (1) and slide out out the inner
rail completely to separate the rails.
1.2.3 Connect the Inner Rail to the UNS
1Connect the inner rail to the UNS by latching it onto the screws on the UNS body.
2Repeat this procedure for the other inner rail on the other side of the UNS.
1.2.4 Connect the Outer Rail to the Rack
Find a space in the rack that is 2U high. The space between two triangles is 1U high.
1Adjust the length of the outer slide rail to the depth of the rack. The front of the outer rail can slide
out. This is the side that should be at the front of the rack.

2Screw the outer rail onto the side of the rack using the M6 screws and nuts. Repeat for the other
side of the rack.
1.2.5 Insert the UNS into the Rack
It is recommended that two people insert the UNS (with inner railings attached) into the rack.
The inner rail (attached to the UNS) has two locks. Use the inner lock to slide the inner rail into the
outer rail (already attached to the rack).
1Release the inner lock and slide the UNS with inner rail attached onto the outer rail already fastened
to the rack.
2Push the inner rail all the way into the outer rail.

Push the latch on the right (1) to release the front handle of the hard drive tray (2). Gently slide out
the hard drive tray (3).
This is the empty hard drive tray.
Place a compatible hard drive into the hard drive tray as shown.
Turn the tray over while holding the hard drive inside and fasten the hard drive to the tray with the
provided screws. The screw positions for 3.5 inch hard drives and 2.5 inch hard drives are shown in
the figure.

Note: Make sure the screws are fastened tightly as protruding screws will impede
insertion of the hard drive tray into the UNS.
Put the hard drive tray back into the UNS by sliding it gently all the way in, and then closing the
front.
Note: Do NOT close the front handle before you slide the hard drive tray all the way back
in.
1.4 About the Power Modules
There are two power module slots with two power modules. One module is redundant, so if one
power module fails the system can operate on the remaining module. It is recommended that you
use two power modules.

1.9 Configure the UNS Using the Web Configurator
The web configurator is a HTML-based program you use to configure the UNS with your web
browser.
The default login name and password is ‘admin’ and ‘1234’.
Use the menus on the left to configure the UNS. See the User’s Guide or the web help to find more
information on these screens.
1.9.1 Choose a RAID Configuration
It is important that you choose your RAID carefully. Changing RAID later requires that you back up
all the data first and then restore it after your new RAID has been configured.

Chapter 1 Hardware Installation
