SL1100
Powering the AP20
The AP20 can only be powered using Power over Ethernet (PoE) 802.3af.
A PoE switch is a switched hub that also provides power over the spare pairs. The switch can be used
with other devices than the IP telephones and detects whether or not power is needed. Using a PoE
switch makes it easier to protect the IP telephones from loss of power (connection of the PoE switch to
an UPS).
Updating the AP20 and ML440 System Firmware
The firmware on base stations and handsets is updated remotely using the HTTP configuration
interface to download firmware files from a TFTP server. Updating base station firmware involves an
automatic reboot of the base station at the end of the firmware download. This will drop any active
calls and in addition updating the handset firmware can take several hours. It is recommended
I
updates are performed after normal business hours. Refer to the ML440 and AP20 System Installation
Guide for detailed information.
