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 AC power (or input power), upper power, or lower power LEDs do not come on, or if the
DC fail (or out fail) LED on any power supply does come on, proceed to the next section,
"Troubleshooting the Power Subsystem."

The LEDs on the RP, which is located in the far right slot (RP slot) in the rear of the chassis, and
the normal LED on the front of the chassis, should come on as follows:
— The RP boot error LED comes on for 1 to 2 seconds when the system boot sequence is
initialized, but it should otherwise remain off. If the system software is unable to start up,
this LED will come on and remain on.
— The RP normal and front panel normal LEDs come on after the system has completed a
successful boot to indicate normal system operation. Once these LEDs come on they should
remain on.
— The CPU halt LED should always remain off. This LED comes on only if the system detects
a processor hardware failure.
If the normal LEDs on the RP and chassis front panel do not come on, or if either the boot error
or CPU halt LED comes on and remains on, proceed to the section "Troubleshooting the RP
Subsystem" later in this chapter.
•
The enabled LED on the SP (or SSP) and on each interface processor comes on when the RP has
completed initialization of the interface processor or SP (or SSP) for operation. This LED
indicates that the SP (or SSP) or interface processor is receiving power and has been recognized
by the RP; it does not indicate the state of the individual interfaces on the interface processors. It
does, however, indicate that an interface processor or SP (or SSP) contains a valid microcode
version. If an enabled LED fails to come on, proceed to the section "Troubleshooting the SP (or
SSP) and Interface Processor Subsystem" later in this chapter.
— 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, refer to the
section "Connecting the Console Terminal" in the chapter "Installing the Router" to verify
that the terminal is set correctly and that it is properly connected to the RP console port.
