with the active card does the inactive card begin to forward packets

across the backplane.

The phases of the initialization processes and their approximate times are

shown in Table 25.

Using the LEDs

to Monitor the

Initialization

Process

There are two ways to monitor the phases of the initialization process. One

way is to use the LEDs on the control card. For phase 1, examine the M/S

LED in the System Status LEDs on the control card. It flashes amber while

the card initializes its management software and changes to solid green at

the completion of the phase. If the chassis has two control cards, the M/S

LED continues to flash amber on the inactive card until the card has

synchronized its database with the active control card.

To monitor phase 2, watch the SBx Status LEDs. There are twelve LEDs

(numbered 0 to 11), one for each slot. The LED for a slot flashes green

while the card initializes its management software and configures its

settings in accordance with the settings from the active control card. The

LED changes to solid green when the corresponding line card completes

the initialization process and begins forwarding traffic.

If there are two control cards, you can monitor phase 3 by viewing the M/S

LEDs on the control cards. The LED on the active control card turns solid

green when the card is finished initializing its management software. The

same LED on the inactive LED continues to flash amber until it has

2 The line cards reset, initialize their

management software, and receive their

configuration settings from the active

control card. At the completion of this

phase, the Ethernet line cards begin to

forward traffic from their ports and the active

control card forwards packets across the

backplane. If the chassis has two control

cards, the inactive card does not begin to

forward traffic across the backplane until the

completion of phase 3.

3 The inactive control card matches its

database and load files with the active

control card. After completing this phase,

the inactive card joins with the active card in

provide the full 400Mbps of bandwidth.
