Opmode and Radio Management Concepts
Proper connections to the radios, and careful IP/routing and planning, will enable the network administrator to access and
manage the radios remotely over the network.
Radio management through TCP/IP can be performed from a PC connected to the Ethernet port of the radio.
Furthermore, PCs connected to the AP can manage SUs over the wireless connection. However, a PC connected to an
SU cannot gain direct TCP/IP access to the AP over the wireless connection.
To fully understand radio management for the Access5830 system, it is important to be familiar with the concept of
operation mode or “Opmode.”
APs can be in one of two Opmodes: Opmode “OFF” or Opmode “AP.” When in Opmode “OFF,” the radio is not
transmitting, and is not attempting to associate with the SUs. Alternatively, when in Opmode “AP,” the radio is
transmitting, and is attempting to associate with the SUs. Similarly, SUs have two Opmodes: Opmode “SU” and
Opmode “OFF.”
Certain functions, such as the site survey function and the SU RSSI function can only be performed while the radio is in
Opmode “OFF.” See Appendix D – Command Set Reference for a complete listing of commands, and the appropriate
Opmode(s) for each command.

Notes about Switch Settings
Access5830 firmware includes several “switches” that are used to set certain operational parameters of the radios. Switch
settings can be changed using the HTTP browser interface or the Command Line Interface. For purposes of TCP/IP radio
management, the following three switches are important:
SU Switch 6 - TCP/IP access direct to SU from SU side of network requires that switch 6 (SW 6) be “ON.” SW 6 was
introduced with the FOX series subscriber units and v1.11 firmware for the M5830 Series SU. Default setting for SW
6 (from factory) is “ON.” If SW 6 is off, TCP/IP access to the SU from the SU side of the network is possible only if
the SU’s Opmode is “OFF.”
SU Switch 2 - TCP/IP access to the SU from the AP side of network requires that the SU’s switch 2 (SW 2 – TCP/IP
for AP) be “ON.” Default setting for SW 2 (from factory) is “ON.”
AP and SU Switch 5 – In order to utilize the radio’s HTTP Browser interface, switch 5 (SW 5) must be “ON.”
Default setting for SW 5 (from factory) is “ON.”
