For detailed information on restoring a default or partial default configuration, see Configuring
System Settings on page 4-2 .
1.2.22 DHCP Support
The access point can use Dynamic Host Configuration Protocol (DHCP) to obtain a leased IP address
and configuration information from a remote server. DHCP is based on the BOOTP protocol and can
coexist or interoperate with BOOTP. Configure the access point to send out a
DHCP request searching
for a DHCP/BOOTP server to acquire HTML, firmware or network configuration files when the access
point boots. Because BOOTP and DHCP interoperate, whichever responds first becomes the server
that allocates information.
The access point can be set to only accept replies from DHCP or BOOTP servers or both (this is the
default setting). Disabling DHCP disables BOOTP and DHCP and requires network settings to be set
manually. If running both DHCP and BOOTP, do not select BOOTP Only. BOOTP should only be used
when the server is running BOOTP exclusively.
The DHCP client automatically sends a DHCP request at an interval specified by the DHCP server to
renew the IP address lease as long as the access point is running (this parameter is programmed at
the DHCP server). For example: Windows 2000 servers typically are set for 3 days.
1.2.23 Multi-Function LEDs
The access point houses seven LED indicators. Four LEDs exist on the top of the access point and are
visible from wall, ceiling and table-top orientations. Three of these four LEDs are single color activity
LEDs, and one is a multi-function red and white status LED. Two LEDs exist on the rear of the access
point and are viewable using a single (customer installed) extended light pipe, adjusted as required
to suit above the ceiling installations.
For detailed information of the access point LEDs and their functionality, see AP-5131 LED Indicators
on page 2-21 .
1.3 Theory of Operations
To understand access point management and performance alternatives, users need familiarity with
access point functionality and configuration options. The access point includes features for different
interface connections and network management.
