Chapter 2 Alarm Troubleshooting
2.7.273 MEA (EQPT)
Clear the MEA (BIC) Alarm
Step 1 Click the Provisioning > Inventory tabs to determine your backplane model. If the backplane is not a
15454-SA-HD, replace the backplane or do not attempt to use high-density DS-3 cards. Table 2-18 lists
the BICs that are compatible with various backplanes.
Step 2 If you determine that your BIC type and backplane are compatible despite the MEA alarm, or if the alarm
does not clear after you resolve the incompatibilities, log into the Technical Support Website at
http://www.cisco.com/techsupport for more information or call Cisco TAC 1 800 553-2447 in order to
report a Service-Affecting (SA) problem.
