Verifying the Installation
Route Switch Processor LEDs (Cisco 7507)
Figure 16 shows the two LEDs on the RSP2. They indicate the system and RSP2 status. The normal
LED goes on to indicate that the system is operational. During normal operation, the CPU halt LED
on the RSP2 should be off and stay off unless the system detects a processor hardware failure. A
successful boot is indicated when the normal LED comes on and stays on; however, this does not
necessarily mean that the system has reached normal operation. The slot 0 and slot 1 LEDs indicate
which PCMCIA slot is in use and blink when either slot is being accessed by the system, if a Flash
memory card is installed.
