IXWLAN SED-MR+
The IxWLAN SED-MR+ chassis has two LEDs associated with each WLAN
port (wport) or Radio (that is, six LEDs in all).
During power-up, the left LED blinks briefly, while the right LED goes off solid.
After booting, the left LED turns on solid, while the right LED turns off solid.
In the idle state (in which no wports are joined and there is no activity), the left
LED turns solid on, while the right one goes off solid.
In the joined state (in which the wport has joined with an AP), both LEDs blink
briefly, yet faster than while power-up. To show network activity (from a joined
state), both LEDs blink proportional with the tx/rx bit rates.
Radio
Characteristics
IxWLAN conforms to the IEEE 802.11a, 802.11b and 802.11g specifications. In
the 802.11a mode, it operates in the 5GHz UNII band. Data is transmitted over a
half-duplex radio channel, operating at up to 54 Mb/s using OFDM. In the
802.11b mode, IxWLAN operates in the 2.4 GHz band and sends data at up to 11
Mb/s. In the 802.11g mode, IxWLAN operates in the 2.4 GHz band, using
OFDM at rates of up to 54 Mb/s.
Antennas
The IxWLAN SED chassis provides two antennas, one each for the 802.11 b/g
mode and 802.11a mode. On the IxWLAN SED-MR+ chassis, there is a single
antenna for each of the 3 independent wports, each handling 802.11b/g, as well
as 802.11a mode.The antennas can be swiveled 180 degrees and angled up or
down to optimize signal gain.
Please note that the antennas are shipped separately and need to be attached to
the chassis. For more details about the installation, please refer to Chapter 2,
Installation .
General Usage Notes
1. Intermixing of CLI, Web-Based User Interface, and SDK operations is not
supported.
2. You can access IxWLAN using the serial port or an Ethernet connection. For
a serial port connection, the serial port must be configured as follows: 115200
baud, 8 data bits, no parity, 1 stop bit, no flow control. For an Ethernet con-
nection, the IxWLAN default IP address is
192.168.0.50 . To establish first
communications between the command PC and IxWLAN using an Ethernet
connection, you must set your PC's IP address and network mask to match
this default address (for example, IP address: 192.168.0.2, Netmask:
255.255.255.0). After you establish communications using the default IP
address, you can change the IxWLAN and your command PC address to
match the addressing scheme used in your network.
3. IxWLAN can operate in the 802.11a, 802.11b, or 802.11g wireless mode. The
IxWLAN wireless mode affects the devices that you can select as a System
Under Test. For example, an IxWLAN that is operating in the 802.11a wire-
