AC-Input Power Supply Overview
The Cisco uBR7225VXR router is equipped with the 300W AC-input power supply and the maximum
AC-input power with single or dual power supply configuration is 300W.
The Cisco uBR7246 and Cisco uBR7246VXR routers are equipped with the 550W AC-input power
supplies and the maximum AC-input power with single or dual power supply configuration is 800W.
Note To ensure adequate airflow across the Cisco uBR7225VXR, Cisco uBR7246VXR, and Cisco uBR7246
universal broadband routers’ power supplies, a power supply or a power supply filler plate (with its
attached air dam) must be installed in each power supply bay.
Do not mix AC-input and DC-input power supplies in the same Cisco uBR7246VXR or Cisco uBR7246
chassis.
Cisco uBR7225VXR
The power supply contains a main power switch, the OK LED, and the AC-input power receptacle. The
grounding lug at the rear-bottom portion of the Cisco uBR7225VXR chassis provides a ground
connection for electrostatic discharge (ESD) equipment.
The Cisco uBR7225VXR supports an optional, second power supply for load sharing and power
redundancy. If you purchased a Cisco uBR7225VXR and you want to install a second power supply, you
must order the second power supply separately.
A handle on the AC-input power supply unit provides a grip point for removing and replacing the power
supply. (Figure 1 shows the faceplate of the Cisco uBR7225VXR AC-input power supply.)
A single captive installation screw secures the power supply to the chassis and seats the power supply in
the router midplane. The AC-input power supply has a receptacle for an AC-input power cable. A
modular power cable connects the AC-input power supply to the site AC power source.
Note The AC-input power supply has an electrical current rating of 4A for the Cisco uBR7225VXR.

AC-Input Power Supply Overview
The Cisco uBR7225VXR power supply device does not have a cable retention clip.

The Cisco uBR7225VXR power supply shuts itself down when the input AC voltage, the output DC
voltage, or the internal temperature of the chassis exceeds allowable tolerances. When this occurs, one
or both of the power supply front panel LEDs will turn red. The Cisco uBR7225VXR power supply must
then be reset by manually switching the power switch off and then back on to allow it to recover.
Cisco uBR7246 and Cisco uBR7246VXR
The power supply contains a main power switch, OK LED, and either an AC-input power receptacle, or
two hardwired DC-input power leads and three M5 grounding connectors (depending on the type of
installed power supply). Adjacent to the lower power supply bay, two M5 chassis grounding receptacles
provide a chassis ground connection for electrostatic discharge (ESD) equipment or a two-hole
grounding lug for the AC-input power supplies.
The Cisco uBR7246VXR and Cisco uBR7246 support an optional, second power supply for load sharing
and power redundancy. If you purchased a Cisco uBR7246VXR or Cisco uBR7246 and you want to
install a second power supply, you must order the second power supply separately.
A handle on the AC-input power supply unit provides a grip point for removing and replacing the power
supply. (Figure 2 shows the faceplate of the Cisco uBR7246VXR and Cisco uBR7246 AC-input power
supply.)
Two captive installation screws secure the power supply to the chassis and seat the power supply in the
router midplane. A Power OK LED indicates that the power supply is delivering +5 VDC to the router
midplane.

The AC-input power supply has a receptacle for an AC-input power cable. A modular power cable
connects the AC-input power supply to the site AC power source. A cable-retention clip secures the
power cable to the AC-input power supply.
Note Each AC-input power supply has an electrical current rating of 7A.

Caution When the input power to Cisco uBR7246 universal broadband router power supply is disconnected or
lost, the power supply enters a reset cycle for 10 seconds. Wait at least 10 seconds or move the power
switch from one position to the other to restart the power supply. For example, if the power supply was
on when the power was disconnected or lost, move the power switch to the off position then back to the
on position. If you do not wait the full 10 seconds or move the power switch from one position to the
other, the power supply does not restart.

Electrical Equipment Guidelines
Follow these basic guidelines when working with any electrical equipment:
• Before beginning any procedures requiring access to the chassis interior, locate the emergency
power-off switch for the room in which you are working.
• Disconnect all power and external cables before moving a chassis.
• Do not work alone if potentially hazardous conditions exist.
• Never assume that power has been disconnected from a circuit; always check.
• Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
• Carefully examine your work area for possible hazards such as moist floors, ungrounded power
extension cables, and missing safety grounds.
Telephone Wiring Guidelines
Use the following guidelines when working with any equipment that is connected to telephone wiring or
to other network cabling:
• Never install telephone wiring during a lightning storm.
• Never install telephone jacks in wet locations unless the jack is specifically designed for wet
locations.
• Never touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
• Use caution when installing or modifying telephone lines.
