Yes, when configuring GigaStack ports in a redundant loop it is normal to have one LED amber. This indicates which port has gone into spanning-tree blocking mode in order to prevent a bridging loop. Even if you enter the global config command "no spanning-tree" the GigaStack ports will still have spanning-tree enabled. Also note that when using both ports on a GigaStack GBIC they will operate at half-duplex.
So if I had 5 switches and no redundancy then 2 of them could operate at full duplex? Do I really need the redundancy - I can't see many problems with the GBIC stuff.
Does it matter which cable I disconnect in order to 'insert' the 2 new switches? The reason I ask is because the amber connection is not the cable which is showing as the redundant link in the Cluster Manager sofware - slightly confusing...
