WARNING!
Do not power off the Summit WM200/2000 Controller by using the power switches only. Instead, carry out the entire
procedure as described above. Failure to do so may corrupt the data on the hard disk drive.
Maintaining the Summit WM20 Controller
WARNING!
You should avoid operating the Summit WM20 in a LAN in which the DC voltage is overlaid on the data lines
because the LAN may have switches that connect directly without checking the supply voltage. Depending upon the
transformer at the LAN interface, voltages of up to 500 Volts can be induced. Such peak voltages can destroy the
physical LAN controllers logic.
NOTE
The Summit WM20 can operate with either 110 or 230 V AC.
No electrical connection exists between the Altitude APs and the Summit WM20. The Summit WM20
and the Altitude APs communicate with each other via the IP network. For more information, see the
Summit WM User Guide.
