Diagnostic tools
Use the following diagnostic tools to troubleshoot problems in the 
system, including problems with the ICB. When diagnosing ICB 
problems, use the following tools:
LED indicators
display codes
card self-tests
sanity monitoring
diagnostic commands (that is, overlay commands for the CS 1000 
and MAP commands for the CS 2100/Meridian SL-100)
history files
TCP/IP connectivity test
ICB status LED indicator
The ICB has a red LED indicator at the top of the faceplate that 
indicates the status of the card. If the LED is lit, the card can be faulty 
or manual busy (Man). The card goes through a series of tests. When 
inserted into the slot or reset, the card:
blinks three times during self-test
runs software files from the PCMCIA to the ICB card
blinks three more times
stays on until a return to service (RTS) occurs
This procedure takes approximately 45 seconds. If the card turns on 
and remains on without blinking, the card is not functioning correctly. 
The LED turns off when the card returns to service.
Power Up Self-test
The ICB card has testability features that aid in fault isolation. When 
inserted into an operating system module, when it is powered up, or 
when the system is reset, each ICB card automatically performs a 
Power Up Self-test. A Power Up Self-test can be performed on a card 
using software commands or menus.
