2. Scans the backplane for configuration changes.
3. Initializes the newly inserted module. In addition, the system notes any removed modules and places those
modules in the administratively shutdown state.
4. Places any previously configured interfaces on the module back to the state they were in when they were
removed.
The router runs diagnostic tests on any new interfaces and the test results indicate the following:
• If the tests pass, the router is operating normally.
• If the new module is faulty, the router resumes normal operation but leaves the new interfaces disabled.
• If the diagnostic tests fail, the router stops operating, which usually indicates that the new module has a
Caution
To avoid erroneous failure messages, note the current configuration of all 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 standby RSP.
Installing the Power Supply
The Cisco ASR 907 Router router provides the choice of two different power supplies:
• 1200 W DC power: - 40.8VDC to -72VDC
• AC power: 85VAC to 264VAC
Caution
The power supply must be wired before plugging the power supply in the chassis. Ensure the branch circuit
breaker is turned off. Only after installing the power supply in the chassis, should the branch circuit breaker
be turned on. The branch circuit breaker must be turned off before unplugging the power supply.
Each power supply provides a single primary input power connection. You can install dual power supplies
for redundancy.
Warning
Read the installation instructions before connecting the system to the power source. Statement 10

problem in the bus and should be removed.
The DC power supply uses 3 position terminal block-style connector with positive latching/securing and
labeled connections for 48V, GRD, 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.
The AC power supply has an IEC-320-C21-type power receptacle and a 20 A 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.
