UPS Setup

The Dell Line-Interactive Rack UPS can be installed in 19-inch racks and needs only 2U of valuable rack

space (3U for 2700/2300W UPS models).

NOTE:

No tools are needed to attach the rack rails to a round- or square-hole EIA rack.

The 2700/2300W UPS models are designed for flexible configurations and can be installed in a rack or

as a standalone cabinet.

If you are installing the UPS in a rack, continue to the following section, “Rackmount Setup.” To install

the 2700/2300W UPS as a standalone cabinet, continue to “Tower Setup” on page 24.

Rackmount Setup

CAUTION: The cabinet is heavy (see page 65): 1) Dell strongly recommends to remove the battery tray from the

UPS before lifting. 2) Lifting the cabinets into the rack requires a minimum of two people.

CAUTION: Removing the batteries should be performed or supervised by personnel knowledgeable about

batteries and the required precautions. Keep unauthorized personnel away from batteries.

CAUTION: If installing an optional EBM, install the EBM directly below the UPS.

NOTE: Mounting rails are required for each individual cabinet.

To install the UPS and optional EBM in a rack:

1 Remove the internal battery tray from the UPS:

Loosen the thumbscrew on the metal battery cover, slide the cover to the right, and open (see

Figure 12).

Figure 12. Opening the Metal Battery Cover

20

|

Installation

Unclip the right battery connector and move the connector out of the way.

Pull the battery tray out using the plastic tabs and remove the battery tray (see Figure 13).

Figure 13. Removing the Battery Tray

2 If installing additional UPSs, repeat Step 1 for each cabinet.

NOTE:

The instructions are the same for square-hole racks and unthreaded, round-hole racks. The rails fit both

rack styles. The square-hole rack is shown in the illustrations.

3 Select the proper holes in the rail for positioning the cabinet in the desired location in the rack.

The rails should be located at the bottom of the 2U (or 3U for 2700/2300W UPS models) space

allocated for the UPS or EBM.

4 Position the end of the left and right rails labeled FRONT facing inward.
