WARNING!
The Summit WM200/2000 Controller should not be operated in a LAN wherein a DC voltage is overlaid on the data
lines, since there may be switches that still connect directly without checking the supply voltage. Depending on the
transformer at the LAN interface, voltages of up to 500 V can be induced. Such peak voltages usually lead to
destruction of the physical LAN controller's logic.
The Summit WM200/2000 Controller consists of a cassette with a cPCI backplane, NP4000 Blade,
MF1000 card, Blade module, SC1100 module, power supply unit and redundant fan modules.
Depending on the power supply module used, it can operate with either 110 or 230V AC.
There is no electrical connection between the Altitude APs and the Summit WM200/2000 Controller.
The Summit WM200/2000 Controller and the Altitude APs communicate with each other exclusively
via the IP network. For more information, see the Summit WM User Guide.
