ML440 Wireless IP DECT Installation Checklist
Step 1. Before Going On-Site
1. You must have 802.3af-2003 PoE (Power over Ethernet) capability at the installation site.
The site must be equipped with a PoE Ethernet switch or a DSX IPA (IP Phone Adaptor P/N 1091045B) to
power the AP20 Access Point. The AP20 does not have a separate external power supply and obtains power
only from PoE.
2. The router at the installation site must be set up as a DHCP server.
By default, the AP20 Access Point is set as a DHCP client and can obtain an IP address for programming
only from a DHCP server.
3. Make sure at least one of the ML440 handsets is adequately charged.
Once the site AP20 Access Point is up and running, you'll use an ML440 handset to find the AP20 IP address
for programming.
Step 2. Connect the AP20 Access Point to the Site Router
1. Verify that the PoE switch or DSX IPA is plugged into the site LAN.
2. Using a CAT5 (or higher) Ethernet cable, plug the AP20 Access Point into the PoE switch or DSX IPA.
Refer to the installation instructions that came with your switch or IPA for more.
3. Monitor the AP20 Access Point Status LED.
•
When you first plug in the AP20 Access Point, the Status LED on the front of the unit will briefly flash
orange.
•
The Status LED will go out and the AP20 Access Point will start to boot.
•
After about one minute, the Status LED will turn green. The AP20 Access Point is now operational and ready
for programming.
