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:

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).
