Cable Connections: Dell® PowerEdge®
Rack-Mountable Solutions Installation Guide
Overview | Safety Information | Connecting the Equipment
This file provides general instructions on connecting the
power and data cables to the equipment in the rack.
When connecting equipment in the rack to a power source, Dell
recommends that you follow these guidelines:
- If you have installed servers or storage systems with
redundant power supplies, connect each power supply to a
separate dedicated service outlet. If a UPS is installed
in the rack, Dell suggests that you connect one power
supply in a system to a UPS connected to a dedicated
circuit, and the other power supply in the system to a
power strip connected to a separate dedicated circuit. To
avoid a single source of failure, do not connect both
power supplies in a system to the same UPS.
- Do not use one dedicated service outlet to power more
than two systems.
|
CAUTION: Ensure that the total
power requirements of equipment in the rack (see Table 1,
UPS Power Ratings) are
distributed properly to avoid exceeding the 15-A rated
capacity of each power strip.
|
|
WARNING: You must plug the power
input cable of the UPS or power strip into a two-pole,
three-wire grounding AC power outlet. Do not use an
extension cable or adapter plug.

| * The power factor of a system
determines how much output current is available from the
UPS. If the system's power factor is greater than 0.90,
use the lower output amp value for the UPS. If the
system's power factor is 0.60 to 0.70, use the higher
output amp value. |
Refer to the following sections when connecting power and data
cables to the equipment in the rack.
Preinstalled Cables for Servers and Storage Systems
If you are setting up a rack that has been preconfigured by
Dell, the power and data cables for any servers puchased with the
rack have been preinstalled on the cable-management arms in the
rack. For identification purposes, each end of a double-ended
cable (such as SCSI cables and serial cables leading from a
computer to the switch box) is labeled with a matching number.
Cable Connections for the Switch Box
Follow these steps to connect the switch box to the servers in
the rack:
- Connect the cables leading from the keyboard, mouse, and
monitor to the switch box's back panel (see Figure 1, Back-Panel Connections for the
Switch Box).

- For each server in the rack, connect the
server-to-switch-box interface cables to the appropriate
keyboard, mouse, and video cable connectors on the
server's back panel and the switch box's back panel.
The keyboard cable is marked with a red arrow, whereas
the mouse cable is marked with black arrows.
- Connect the switch-box power cable to a power source in
the rack.

Cable Connections for the UPS Power Management Software
If you want to use the UPS power management software, connect
the serial connector on the UPS back panel to the
"master" computer that will control the UPS power
management features. If a UPS interface card is installed in the
UPS, connect any other protected computers or storage systems to
the serial connectors on the UPS interface card.
