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.
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 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.
Attach the rails to the rack: Engage the back end of the rail until it fully seats on the vertical rack flange and the hook latch locks in place (see Figure 14). Pull the rail toward the front. Push the front end of the rail until it fully seats on the vertical rack flange and the hook latch locks in place.
Slide the cabinet into the rack (see Figure 15). Repeat for any additional cabinets. Figure 15. Installing the Cabinet Secure the front of the cabinet to the rack using the four thumbscrews on the mounting brackets (see Figure 16). Tighten by hand; do not use power tools. Repeat for any additional cabinets. Figure 16.
Install the UPS battery tray (see Figure 17). NOTE: A small amount of arcing may occur when connecting the batteries. This is normal and does not damage the unit or present any safety concern. Connect the internal battery connector and reclip the right battery connector. Close the metal battery cover.
Install the UPS front cover (see Figure 18). Figure 18. Installing the UPS Front Cover Tower Setup CAUTION: The UPS and EBM are heavy (see page 65). Lifting the cabinets into the pedestals requires a minimum of two people. To install the 2700/2300W 3U UPS model in a tower configuration: ®...

NOTE: Dell recommends a minimum of 63.5 mm (2.5”) free space behind the UPS rear panel, and a minimum of 127 mm (5”) between cabinets. Place the cabinet horizontally so that the right end of the cabinet is accessible (see Figure 24).
Installing the EBM NOTE: A small amount of arcing may occur when connecting an EBM to the UPS. This is normal and will not harm personnel. Insert the EBM cable into the UPS battery connector quickly and firmly. An optional EBM can be installed for 1920–2700W UPS models. To install the optional EBM: Remove the battery connector cover from the rear panel as shown in Figure 26.
Install the battery connector cover under the EBM cable to provide strain relief (see Figure 27). Rotate the battery connector cover on its side and position under the EBM cable. Figure 27. Installing the Battery Connection Cover Plug the EBM cable into the UPS battery connector (see Figure 28). Secure the battery connector cover to the UPS rear panel using the screws removed in Step 1.
Installing the UPS To install the UPS: If you plan to use Dell UPS Management Software, connect your computer to the USB port using the supplied cable. For more information about communication options, see page 56. If your rack has conductors for grounding or bonding of ungrounded metal parts, connect the ground cable (not supplied) to the ground bonding screw.

When the UPS has a critical alarm, the backlight changes the text to dark amber and the background to amber. See Figure 30. Figure 30. Dell Line-Interactive Rack UPS Control Panel There are three buttons on the control panel:...
Startup Screen During startup, the Dell logo is the default screen. This startup screen displays for five seconds and then defaults to the UPS status summary screen. The display automatically returns to the UPS status summary screen when no button has been pushed for 15 minutes and no other screen has been locked by a user.
Screen Locked To lock a screen, press the button. The current view stays locked and does not automatically return to the default screen after time-out. When the screen is locked, the image of a key appears on the UPS status summary screen just to the left of the status icon. See Figure 31. Pushing any button returns the normal button function, unlocks the screen, and removes the lock symbol.

Configuring Load Segments Load segments are sets of receptacles that can be controlled by the Dell UPS Management Software, the Dell Network Management Card, or through the LCD display, providing an orderly shutdown and startup of your equipment. For example, during a power outage, you can keep key pieces of equipment running while you turn off other equipment.
Configuring Automatic Start Delay You can configure the load segment to turn on automatically after the utility power returns, if it was shut down by: S The button S An external command with auto-restart option S Battery under voltage state S Automatic on battery shutdown command You can specify the restart delay time for each load segment: select zero seconds (0s is the default) to restart immediately, select 1–32767 seconds to delay for the specified time, or select Off.
Configuring Automatic on Battery Shutdown If set to Off (default), the load segment turns off only when commanded manually by the button, an external command, or through the display (Control > Load Segments). If set to zero seconds (0s), the load segment turns off automatically when the UPS on Battery state activates.
Configuring Battery Settings Configure the UPS settings for an installed EBM, including whether to run automatic battery tests and automatic restart configuration. Configuring the UPS for an EBM If the UPS is not configured for the EBM, the UPS reports less battery time remaining on the UPS front panel and to any remote software.
Running Automatic Battery Tests The automatic discharge test, enabled by default, runs during the transition from Float to Rest mode. After the test completes, the charge cycle restarts to completely charge the batteries and then continues to Rest mode normally. The automatic test runs approximately once every three months and does not run again until after three more Float to Rest mode transitions.

It also gives you a complete record of critical power events, and it notifies you of important UPS or power information. If there is a power outage and the Dell Line-Interactive Rack UPS battery power becomes low, the software can automatically shut down your computer system to protect your data before the UPS shutdown occurs.
UPS Maintenance This chapter explains how to: S Care for the UPS and batteries S Transport the UPS S Store the UPS and batteries S Test the batteries S Update the UPS firmware UPS and Battery Care For the best preventive maintenance, keep the area around the UPS clean and dust‐free. If the atmosphere is very dusty, clean the outside of the system with a vacuum cleaner.
Transporting the UPS NOTE: The internal UPS batteries MUST be disconnected before transportation. CAUTION: The following procedure should be performed or supervised by personnel knowledgeable about batteries and the required precautions. Keep unauthorized personnel away from batteries. If the UPS requires any type of transportation, the batteries must be disconnected (but not removed) before the unit is transported: Verify that the UPS is off and unplugged.
Open the metal battery cover. Loosen the thumbscrew on the metal battery cover, slide the cover to the right, and open (see Figure 35). Figure 35.
