A power switch is located on the upper right-hand corner of the SFCS- 200WG. When the power is turned on, the power LED, located to the right of the display LED, illuminates green and the initial power-on diagnostics are run. When the power is turned off, the power LED is extinguished.

3.2.3 Network Modules

The network modules in a Cabletron switch board act as the physical input/ output ports to the switch board. A network module may have one, two, four, or six physical ports, depending on its configuration.

3.2.3.1Port Numbering

The individual ports on a network module are numbered according to the Board-Network Module-Port (BNP) notation.

Board Refers to the number of the switch board that contains the port being numbered. “Board” is always 1 in an SFCS-200BX, or an SFCS-200WG, since these switches each contain only one switch board. “Board” can be 1, 2, 3, or 4 in an SFCS-1000, depending on the number of the physical switch board that contains the port being numbered.

Network Module Refers to the slot (A, B, C, or D) in the switch board that contains the port being numbered.

Port Refers to the physical port (1 - 6) being num- bered on the individual network module.
