Summit WM Controller WM200/2000 maintenance
WARNING!
The Summit WM Controller WM200/2000 system may not be operated in a LAN in which a DC voltage is overlaid
on the data lines, since there are still switches that connect directly without checking the supply voltage first.
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.
Summit WM Controller WM200/2000 (Figure 9) consists of a cassette with a cPCI backplane, NP4000
Blade, MF1000 Blade module, SC1100 Module, a universal power supply unit, and redundant fan
modules.
There is no electrical connection between the access point and the Summit WM Controller WM200/
2000. The Summit WM Controller WM200/2000 and Altitude APs communicate with each other
exclusively via the IP network. For more information, see the Summit WM User Guide.
