Again a simple question for 99% of Network Engineers, therefore it is expected that this should be configured correct. The ports are edge ports and should move into STP forwarding state immediately. In other words STP portfast needs to be configured.
Rack1SW2(config)#int fa0/2
Rack1SW2(config-if)#spanning-tree portfast
Rack1SW2(config-if)#int fa0/4
Rack1SW2(config-if)#spanning-tree portfast
Verify by either looking at the config or:
Rack1SW2#sh spanning-tree interface fa0/2 portfast
VLAN0002 enabled
Rack1SW2#sh spanning-tree interface fa0/4 portfast
VLAN0004 enabled
