4-Port Gigabit Ethernet Layer 3 Switching Module (GBIC) Quick Start Guide

Verifying Module
Operation
After you install the 4-port Gigabit Ethernet Layer 3 Switching Module
(GBIC), you must wait for the module to complete a successful
initialization process before you can proceed to configure it according to
the needs of your network. This initialization process includes power on
verification tests, diagnostic self-tests, and a software boot cycle.
Front Panel LEDs
The front panel of the 4-port Gigabit Ethernet Layer 3 Switching Module
(GBIC) contains one Module Status LED and four Port Status LEDs that
flash and change color during the module initialization process and
provide status information thereafter.
Port numbers
5 – 8 on the rear of the module do not have Port Status
LEDs on the front panel. After the module initialization process is
complete and the module is ready to manage, you can use the portState
field in the
ethernet detail
display to determine the status of these
ports.
Initial Activity
Whether you power on the chassis after you install the 4-port Gigabit
Ethernet Layer 3 Switching Module (GBIC) or whether you hot insert or
hot swap the module, the EME controls what happens next. The EME
reads the module inventory data that is stored on the module and
determines whether the chassis has sufficient power available to support
the module. The Module LED and Port Status LEDs remain off during this
short evaluation period (approximately 3 seconds).
If the EME does not enable power to the slot, the module initialization
process does not begin. All LEDs remain off until the available power
increases or the power configuration changes.
