Verifying the Installation
Route Processor LEDs (Cisco 7000)
Figure 15 shows the LEDs on an RP installed in the chassis. The three LEDs on the RP indicate the
system and RP status. When the system is turned on or restarted, the boot error LED goes on for one
or two seconds, then goes out. The CPU halt LED, which goes on only if the system detects a
processor hardware failure, should never go on. If the boot error LED remains on for more than five
seconds, the system is unable to boot and should be restarted. A successful boot is indicated when
the boot error LED goes out; however, this does not necessarily mean that the system has reached
normal operation. During normal operation, the CPU halt and boot error LEDs should be off, and
the normal LED should be on.
