When POST completes successfully, the port LEDs return to the status mode
display, indicating that the switch is operational. If a test fails, the port LED
associated with the test turns amber, and the system LED turns amber. If POST
fails, refer to Chapter 3, "Troubleshooting,"
POST failures are usually fatal. Call Cisco Systems immediately if your switch
does not pass POST.
The switch 10/100 Ethernet ports configure themselves to operate at the speed of
attached devices. If the attached ports do not support autonegotiation, you can
explicitly set the speed and duplex parameters.
Connecting devices that do not autonegotiate or that have their speed and duplex
parameters manually set can reduce performance or result in no linkage. To
maximize performance, choose one of these methods for configuring the 10/100
Ethernet ports:
Let the ports autonegotiate both speed and duplex.
•
• Set the port speed and duplex parameters on both ends of the connection.
You can configure the 10/100 ports on the Catalyst 3524-PWR XL switch to
either automatically provide inline power when a Cisco IP Phone is connected or
to never provide inline power even if a Cisco IP Phone is connected. The default
setting is Auto.
It takes a Catalyst 3524-PWR XL 10/100 port up to 10 seconds to
initially detect, power, and link to a Cisco IP Phone. If you
disconnect the Cisco IP Phone before link has been established, you
must wait 10 seconds before connecting another network device
(other than another Cisco IP Phone) to that switch port. Failure to do
so can result in damage to that network device.
