• As soon as you turn on the power switch, you should immediately hear the blower operating. If you
are in an unusually noisy environment, such as an air-conditioned wiring closet with other
equipment noise, place your hand near the middle of the plastic panel on front of the chassis
(opposite the interface processor end of the chassis); you should feel the exhaust air that is being
forced out of the chassis.

of the interface processor for operation. This LED indicates that the interface processor is receiving
power and has been recognized by the RSPs; it does not indicate the state of the individual
interfaces. It does, however, indicate that an interface processor contains a valid microcode version.
If an enabled LED fails to go on, proceed to the

Note
When the LEDs indicate that the system has initialized successfully, the system banner (similar to
the following example) should be displayed on the console screen. If it is not displayed, refer to the
"Connecting a Console Terminal to the RSP" section on page 3-32
correctly and that it is properly connected to the RSP's console port.

If the AC (or DC) OK LED goes on and the system starts up as expected but then displays the
following message and shuts down after 2 minutes, there is a problem with the blower. Proceed

If the AC (or DC) OK LED stays off yet the system starts up correctly, displays the preceding
message, and shuts down after about 2 minutes, there is a problem with the +24 VDC line to the
blower module. Proceed to the

Do not mistake the power supply exhaust air coming from the bottom front panel.
If the AC (or DC) OK LED is on but the blower is not operating, there is a problem with the
blower. (The system will shut itself down if it detects that the blower is not functioning
properly.) Proceed to the "Troubleshooting the Cisco 7513, Cisco 7513-MX, and Cisco 7576
Cooling Subsystem" section on page
If the AC (or DC) OK LED is on at startup and the blower is operating but the system shuts
down after 2 minutes, there might be a problem with the blower control board. Proceed to the

While the system is starting up and initializing the individual interface processors, the status
LEDs on the interface processors will flash on and off or light intermittently; this is normal
behavior. The LEDs do not indicate the true status of the interfaces until the system has
initialized the interface processors and you have enabled the individual interfaces.
