Verifying the Installation

This section describes how to verify the modular port adapter (MPA) installation by observing the MPA LED
states.
When the system has reinitialized all interfaces, the MPA STATUS LEDs should be on (green). The port
LEDs (C/A and A/L) may be on (green), depending on your connections and configuration.
To verify that a MPA is installed correctly:
Procedure
Step 1 Observe the console display messages and verify that the system discovers the modular line card (MLC),
while the system reinitializes each interface, thus:
• As the MPA is initialized, the STATUS LED will first be amber, indicating that power is on. When the
Step 2 When the MPA STATUS LEDs are green, all associated interfaces are configurable.
• If a MPA is replaced with a module of the same type (as in an OIR or hardware swap), the previous
• If a MPA was not previously installed in the same slot or subslot, then the configuration for all associated
Note
Step 3
If the modular port adapters (MPAs) do not become active within three minutes, refer to the system console
messages. If there is no indication that a field-programmable device (FPD) upgrade is underway, see
