subsystem.

The power supply LEDs located on each power supply in the rear of the chassis, and the upper power
and lower power LEDs on the front of the chassis, should come on as follows:
The green AC power LED on the AC-input power supply (or the green input power LED on the
–
DC-input power supply) should come on immediately when you turn the power supply switch
to on (|), and should remain on during normal system operation. On the front of the chassis, the
LED for the corresponding power supply bay (upper power or lower power) should also come
on.
–
The DC fail LED on the AC-input power supply (or the out fail LED on the DC-input power
supply) should remain off. This LED comes on only when the power supply loses input power
or when it is shutting itself down because it detected an out-of-tolerance power or temperature
condition within the power supply. If the LEDs for AC power (or input power), upper power, or
lower power do not come on, or if the DC fail (or out fail) LED on any power supply does come
on, proceed to the
"Troubleshooting the Cisco 7507 and Cisco 7507-MX Power Subsystem"
section on page
8-10.
When you turn on the system power, the LEDs on the RSP (see
Figure 1-8
for the Cisco 7507-MX) should operate as indicated in the RSP installation and
configuration note. The Cisco 7507 and Cisco 7507-MX are compatible with an RSP2, RSP4, and
RSP8. See the installation and configuration note for the RSP model that is installed in your Cisco
7507 or Cisco 7507-MX for detailed operating information.
The enabled LED on each interface processor comes on when the RSP has completed initialization
of the interface processor for operation. This LED indicates that the interface processor is receiving
power and has been recognized by the RSP; it does not indicate the state of the individual interfaces
on the interface processors. It does, however, indicate that an interface processor contains a valid
microcode version. If an enabled LED fails to come on, proceed to the
Interface Processors" section on page
When all LEDs come on to indicate that the system has booted successfully, the initial system
banner should be displayed on the console screen. If it is not displayed, see the
Console Terminal to the RSP" section on page 3-32
that it is properly connected to the RSP console port.
On the lower power supply, is the AC power or input power LED on?
–
If yes, the power source is good, and the power supply is functional.
–
If no, first suspect the power or interlock switch. Loosen the captive installation screw, turn the
power switch fully counterclockwise to the off (O) position, pull the supply out of the bay a few
inches, then push it firmly back into the bay, and ensure that the front of the power supply is
flush with the back of the chassis.
Tighten the captive installation screw, and then turn the power switch clockwise until it is
completely turned to the on (|) position and the interlock tab is fully extended into the interlock
slot in the chassis. (See the
on page
3-14.)
