Product Overview
The 10/100 ports on the Catalyst 3512, 3524, 3524-PWR, and 3548 XL switches
provide protocol support for Cisco IP Phones. The Catalyst 3548 and
3524-PWR XL switches also support per-port priority override. Refer to the Cisco
IOS Desktop Switching Software Configuration Guide for more information about
these features.
Cisco IP Phones—connected to the 10/100 ports on the Catalyst 3512, 3524, and
3548 XL switches—must be connected to an AC power source. However, the
Catalyst 3524-PWR XL 10/100 ports can:
•
•
On a per-port basis, you can control whether or not a Catalyst 3524-PWR XL
10/100 port automatically provides power when a Cisco IP Phone is connected.
CMS and the CLI provide two inline power settings for each 10/100 port: Auto
and Never. When you select the Auto setting for inline power on a port, the port
only provides power if a Cisco IP Phone is connected to it. The Auto setting is the
default. However, when you select the Never setting for inline power on a port,
the port does not provide power even if a Cisco IP Phone is connected to it.
You also can connect the Cisco IP Phone to a Catalyst 3524-PWR XL 10/100 port
and to an AC power source for redundant power. The power source to which the
Cisco IP Phone is first connected becomes its primary power source, and the
second power source is its backup. If the primary source fails, the second power
source becomes the primary power source to the Cisco IP Phone. During the
power transfer, the phone might reboot or reestablish link with the switch.
For information about Cisco IP Phones, refer to the documentation that came with
your Cisco IP Phone.
