Note these additional items:

■The linkState up or down settings apply to Ethernet and Fast Ethernet ports, not to FDDI ports, and only when the stpState for the bridge is enabled. If the stpState on the Bridge menu is disabled, the State for the port remains in forwarding state.

■When the bridge port is in the Removed state, the State remains in forwarding state.

■If STP is disabled on an individual port, the State remains disabled.

Table 1 describes the port states and how they relate to the linkState. This table is valid only when the stpState for the bridge is enabled.

Table 1 Port States When stpState Is Enabled

If STP is	and linkState is	Then Port State is
enabled	up	blocking or forwarding*
enabled	down	disabled
disabled	up	disabled
disabled	down	disabled

*The Port State is either blocking or forwarding. The final state depends on the Spanning Tree configuration of the network.

CoreBuilder 6000 12-Slot Chassis

The CoreBuilder 6000 12-slot chassis is the latest generation of the CoreBuilder 6000 chassis. This chassis and the 8.2.3 software release allow you to remove and replace the power supplies and fan trays in case of failure.

Hot-swappable Power Supplies. The LED on each power supply lights green when the power supply is running correctly. If the power supply fails, the system generates a sound and the power supply LED does not light. You can remove and replace either of the two power supplies at the back of the chassis. (Turning off one of the power supplies generates a sound, and the control panel LCD displays Input Failure.)
