Steps to Take
See the
"System-Wide Problems" section on page
See the
"System-Wide Problems" section on page
1.
Check the connection at the wire-wrap connector on the I/O module. See
on page C-3
for the pin assignments of the wire-wrap connector.
2.
Check the connection at the other end of the circuit.
3.
For a BITS problem, troubleshoot the E1 line at the other end of the circuit.
4.
Replace the I/O module (except in the case of a circuit breaker alarm problem).
Make sure the software release running on your system is compatible with the
1.
hardware. The Cisco 6260 requires Cisco IOS Release 12.1(4)DA or greater.
Enter the command show hardware chassis. In the resulting display, look for data
2.
from the I/O module EEPROM. If the system can read the contents of the EEPROM,
the I/O module is likely to be healthy.
If the I/O module is missing, install it.
3.
4.
If the I/O module is present, reseat it. First, turn off system power. Use a Phillips-head
screwdriver to unfasten the screws that secure the I/O module cover, and pull the card
off the connectors. Push it firmly back into place and tighten the screws.
If the problem persists, replace the I/O module.
