600W DC-Input Power Supply Replacement Instructions 13
Power Supply Replacement
Step 12
If you removed the ground wire, reattach it now. (See Figure 4d on page 9.)
Step 13
Tighten the captive screws on the terminal block cover. (See Figure 4a on page 9.)
Warning
To prevent a short-circuit or shock hazard after wiring the DC-input power supply,
replace the terminal block cover.
Step 14
To replace the chassis cover panel, follow Steps 4 through 7 in the section “Removing and
Replacing the Chassis Cover Panel” on page 6.
This completes the new power supply installation.
To restart the system, connect the three DC-input power cable leads to the DC power source, turn on
power to the chassis, and check the installation by proceeding to the following section,“Checking
the Installation.”
Checking the Installation
To complete the installation perform the following steps to verify that the new component is
installed correctly and functioning properly. These steps will also help you verify that all the active
components that you removed or disconnected as part of this replacement procedure are returned to
their previous state, when all router components (except the power supply you replaced) were
operating properly.
Step 1
Before you turn the system power switch back ON, first ensure the following:
•
The DC-input power cable is attached to the terminal block and the terminal block cover
is installed.
•
The power cable is properly connected to the DC power source.
•
The nylon cable tie is installed as strain relief.
•
The tape (that you applied earlier) is removed from the circuit breaker switch handle and
power is restored by moving the circuit breaker handle to the on position.
Step 2
Turn ON (|) the chassis power.
Step 3
About 10 seconds after you turn ON the power, verify that the normal LED on the RP or
RSP1 goes on, which indicates that the system software booted successfully. If it does go
on, proceed to the next step. If it does not go on, do the following:
•
Check the ejector levers and captive installation screws on the processor modules. If any
appear loose, use the ejector levers to reseat the processor, then tighten the captive
installation screws to secure it. Turn the power OFF and back ON again.
•
While the system starts up, observe the behavior of the LEDs on the RP or RSP1 (so
that you can report the behavior to a service representative if you need to call for
technical assistance). If the RP or RSP1 normal LED still remains off, note whether the
boot fail LED (on the RP) or CPU halt LED (on the RSP1) go on, and contact a service
representative for further instructions.
Step 4
After the system initializes, use the various show environment commands to display the
status of the power supply, and ensure that it is operating within normal specifications. (For
descriptions and examples of these commands, refer to the section “Prerequisites” on page
4.)
