The POWER LED on the front panel of a device either glows green or is off. Green
indicates correct function, and off indicates power-adapter failure or that the device
is off.
The SSG 20-WLAN contains two wireless connectivity radio transceivers, which
support 802.11a/b/g standards. The first transceiver (WLAN 0) uses the 2.4 GHz
radio band, which supports the 802.11b standard at 11 Mbps, the 802.11g standard
at 54 Mbps, and 802.11 SuperG standard at 108 Mbps. The second radio transceiver
(WLAN 1) uses the 5GHz radio band, which supports the 802.11a standard at 54
Mbps. For information on configuring the wireless radio band, see "Basic Wireless
Configuration" on page 37.
A one-hole grounding lug is provided on the rear of the chassis to connect the
device to earth ground (see Figure 6).
To ground the device before connecting power, connect a grounding cable to earth
ground and then attach the cable to the lug on the rear of the chassis.
