To avoid erroneous failure messages, note the current configuration of all the interfaces before you remove
or replace an interface module, and allow at least 2 minutes for the system to reinitialize after a module
has been removed or replaced. This time is recommended in order to allow for synchronization between
components within the interface module and for synchronization with the RSP.
Caution
Installing the Power Supply
The Cisco ASR 902 Router provides the choice of two different power supplies:
•
DC power
◦
550 W Power Supply
—
19.2VDC to -72VDC
The DC power supply uses 3 position terminal block-style connector with positive latching/securing and
labeled connections for +24/48V, GRD, -24/48V. The terminal block connector is of suitable size to carry
the appropriate AWG wire size to handle the input current of the power supply. No ON/OFF switch is provided.
•
1200 W Power Supply
—
40.8VDC to -72VDC
◦
The power supplies are hot-swappable. They are enclosed to prevent exposure to high voltages, and therefore,
no power cable interlock is required. However the power supplies are automatically shut down when removed
from the chassis. The power supplies are rated to deliver 975 W (~81 A) to the other FRUs in the system, and
are rated for operation at 5ºC above the chassis operating temperature
•
AC power
◦
550 W Power Supply
—
85VAC to 264VAC
◦
1200 W Power Supply
—
85VAC to 264VAC
The power supplies are hot-swappable. They are enclosed to prevent exposure to high voltages, and therefore,
no power cable interlock is required. However the power supplies are automatically shut down when removed
from the chassis. The power supplies are rated to deliver 975 W (~81 A) to the other FRUs in the system, and
are rated for operation at 5ºC above the chassis operating temperature.
The AC power supply has an IEC 320-type power receptacle and a 15 Amp service connector. You can use
standard right angle power cords with the AC power supply. The power supply includes a power cord retainer.
No ON/OFF switch is provided.
LEDs are also provided on each power supply to indicate the status of the input power and the health of the
power supply. Each power supply also includes a board ID EEPROM which is accessible by the active RSP.
Each power supply provides a single primary input power connection. You can install dual-power supplies
for redundancy.
Read the installation instructions before connecting the system to the power source. Statement 1004
