Application Gateway 2246 in a space with:

•sufficient backboard mounting space and proximity to the LAN access device (switched Ethernet switch), Call Server, and power source

•rack-mount unit (if using)

•easy access to the front panel, which is used for cabling

•for the WLAN Application Telephony Gateway 2246, a maximum distance of 325 feet (100 meters) from the Ethernet switch

IP address planning

The WLAN IP Telephony Manager 2245, the optional WLAN Application Gateway 2246, and each of the wireless handsets and APs associated with them, requires an IP address.

ATTENTION

IMPORTANT!

The master WLAN IP Telephony Manager 2245 must have an IP address statically configured.

If using DHCP for the rest of the network, the DHCP Server must have the static IP address of the master WLAN IP Telephony Manager 2245 configured on it. If using DNS, the DNS Server must have the static IP address of the master WLAN IP Telephony Manager 2245 configured on it.

The wireless handsets can be configured to use DHCP or can be assigned a static IP address. If there is no DHCP Server, the system administrator must determine what IP addresses are to be used for static addressing. As well, whether static IP addressing or DHCP is used, a pool of alias IP addresses must be configured on the WLAN IP Telephony Manager for the use of the wireless handsets. Ensure that the pool of alias IP addresses is reserved exclusively for the use of the wireless handsets.

For information about configuring a static IP address on a WLAN IP Telephony Manager 2245, see "WLAN IP Telephony Manager 2245 configuration" (page 99). For information about configuring a static IP address for a WLAN Application Gateway 2246, see "Configuring the WLAN Application Gateway 2246 IP address" (page 152). For information about configuring a static IP address on the handsets, see WLAN Handsets Fundamentals (NN43001-505). For information about assigning IP addresses to the APs, see the vendor-specific documentation.
