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 
Table 25.   Switch Initialization Phases

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.

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 
forwarding traffic across the backplane, to 
provide the full 400Mbps of bandwidth.
