3.2.2.1.1RESET 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.

3.2.2.1.2RS-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.
