Front Panel Description
• SFP port LEDs 3 and 4 on the Catalyst 3750-48TS switch show the status for
StackWise ports 1 and 2, respectively.
• SFP port LEDs 27 and 28 on the Catalyst 3750G-24TS switch show the status
for StackWise ports 1 and 2, respectively.
• The 10/100/1000 port LEDs 23 and 24 on the Catalyst 3750G-24T switch
show the status for StackWise ports 1 and 2, respectively.
• SFP port LEDs 11 and 12 on the Catalyst 3750G-12S switch show the status
for StackWise ports 1 and 2, respectively.
Note If both the port LEDs are green on all the switches in the stack, the stack is
operating at full bandwidth (32 Gbps). If any of the port LEDs are not green, the
