The WLAN LEDs are only present on the SSG 20-WLAN device.
Figure 3: Status LEDs
When the system powers up, the POWER LED changes from off to blinking green,
and the STATUS LED changes in the following sequence: red, green, blinking green.
Startup takes approximately two minutes to complete. If you want to turn the
system off and on again, we recommend you wait a few seconds between shutting
it down and powering it back up. Table 2 provides the name, color, status, and
description of each system status LED.
