Cisco 7507 and Cisco 7507-MX LEDs

Three system status LEDs on the front of the Cisco 7507 and Cisco 7507-MX (see Figure 8-4) indicate the status of the system and the power supplies. The normal LED goes on to indicate that the system is in a normal operating state. The normal LED is controlled by the RSP2, which contains an identical normal LED that provides system status on the rear of the chassis.

The upper power and lower power LEDs go on to indicate that a power supply is installed in the indicated power supply bay and is providing power to the system. The power LEDs go out if the power supply in the corresponding bay reaches an out-of-tolerance temperature or voltage condition. (For detailed descriptions of the show commands that display temperature and voltage information, see the “Cisco 7507 and Cisco 7507-MX Environmental show Command Examples” section on page 2-29.)

Cisco 7513, Cisco 7513-MX, and Cisco 7576 LEDs

Three system status LEDs on the front of the Cisco 7513, Cisco 7513-MX, and Cisco 7576 (see Figure 8-5) indicate the status of the system and the power supplies. On the Cisco 7513 and Cisco 7513-MX the normal LED lights to indicate that the system is in a normal operating state. The normal LED is controlled by the RSP, which contains an identical normal LED that provides system status on the rear of the chassis.

Note The Cisco 7576 front panel normal LED stays lit whenever there is a functioning RSP in either slot 6 or slot 7. This LED only goes out if there are no RSPs present, or if both RSPs are not functioning. If you need to troubleshoot the normal status of a Cisco 7576, view the normal LEDs on the RSPs instead of the normal LED on the front panel.

The power A and power B LEDs light to indicate that a power supply is installed in the indicated power supply bay and is providing power to the system. With the chassis oriented as shown in Figure 1-11, the power A bay is on the left and the power B bay is on the right.
