3.2.2.1.8 Power LED
The power LED that is located to the right of the display LED on the front
panel of the SCP reflects the current state of power to the SCP. Table 1.4 lists
the states of the power LED and their meanings.
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.
3.2.3.1 Port 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.
