Switch Hardware
3.2.2.1 i960 Switch Control Processor
The front panel of an i960 SCP for the SFCS-200WG, SFCS-200BX, and the
SFCS-1000 includes the following features: a RESET button, an RS-232 serial
port, an Ethernet 10BaseT port, a NEXT pushbutton, a SELECT pushbutton, a
display LED, and a power LED. All of the features are illustrated in Figure 3.4
and are described in detail in the subsections that follow.

3.2.2.1.1 RESET Button
The RESET button allows the user to reset the switch control software on the
SCP. Using RESET “soft boots” the SCP and runs the initial power-on diag-
nostics. All open AMI sessions are ended by the SCP, and all ports lose any
active sessions and initially go off-line after a reset. The ports then return to
the configuration stored in the CDB. Because the RESET button is small (to
avoid accidental resets), it is recommended that you use a straightened paper
clip to push the RESET button.
3.2.2.1.2 RS-232 Serial Port
The RS-232 serial port provides terminal access for any VT100 (or similar) ter-
minal or terminal emulation package to the SCP. The serial port has a stan-
dard DB-9 female connector as shown in Figure 3.5.
