The functional definitions of the Summit WM20 Controller’s LEDs are provided below:
● ACTIVITY LED – Indicates the CPU activity, including the amount of traffic carried to and from the
Wireless APs.
● STATUS LED – Indicates the normal state of the Summit WM Controller as seen by the system’s
software. This LED covers all stages of the Summit WM Controller, ranging from restarting, to
shutting-down. As long as the Summit WM Controller is running normally, this LED will remain lit.
● HDD Activity LED – Is hardware controlled to report Hard Drive Device (HDD) activity.
● Hot Swap LED – Indicates that the hot swap lever on the Summit WM Controller has been pulled.
For information, see “Summit WM20 Controller front panel” on page 23.
NOTE
The hot swap lever is not enabled in the current release. Pulling the hot swap lever will not affect the normal
operation if the Summit WM20 Controller is already running. However, if you attempt to reboot the Summit WM20
Controller with the hot swap lever pulled out, the controller will fail to reboot. If you pull the hot swap lever while
the Summit WM20 Controller is in operation, the Hot Swap LED will light up.
