Verifying the Installation
To verify the hardware installation, observe the front panel indicators.
In normal operation:
 The POWER A LED and/or the POWER B LED are in the ON state (green).
— If you are using dual power sources, both Power LEDs must be ON.
— If you are using a single power source, the appropriate Power LED (either
Power A or Power B) must be ON.
 The FAN ALARM LED must be OFF.
 If you installed an SCP card, verify that the SYSTEM ACTIVE or STANDBY
LED is cycling off and on.
 If you installed an MCP or SCM card, verify that the SYSTEM OK LED is
cycling off and on.
 Verify that the SYSTEM OK LEDs on any line cards are cycling off and on.
If these LEDs fail to appear as described, see Troubleshooting Table and LEDs in
Chapter 6, Troubleshooting, for more information.
