To seat the module, firmly push the module forward to engage the module
and backplane connectors. You will feel a slight resistance as the connectors
engage.
CAUTION:
If the resistance is too great, the module and backplane connec-
tors may not be aligned. Forcing the module forward could damage the
board or backplane connectors. If necessary, remove and reinsert the
module, ensuring that the connectors are properly aligned. You should not
have to seat the module by tightening the captive screws.

power on. During diagnostics, the module’s port status
Error
LEDs are lit
yellow. When diagnostics are successfully completed, the port status
Active
LEDs turn green for those ports that are cabled. If any port status
Error

remain yellow, the port is not operational. If the module’s
Board Error

is lit yellow, the module has failed a diagnostic test. To troubleshoot module
failures see Chapter 7:
