ACCESSING THE CYBERSWITCH

Making Connections

6.Turn on the CyberSWITCH by pressing the POWER-ON button.

7.Turn on the monitor.

8.After a few seconds, power-on initialization will begin. Proceed to Establishing an Administrative Session.

NULL-MODEM CONNECTION TO A PC

If you wish to use an IBM-compatible PC to locally administer your system, you will need to establish a null-modem connection between PC and CyberSWITCH. You will also need the optional Manager diskette which includes Carbon Copy software. Carbon Copy allows you to manage and configure your CyberSWITCH as if it were a direct connection, and additionally provides a means for file transfer. Refer to the Carbon Copy discussion in the Remote Management chapter for more information.

Physical Connections:

1.Use a null-modem cable (with 9-pin female RS232 connectors) to connect the 9-pin, male RS232 port on the CyberSWITCH to the 9-pin, male RS232 port on the PC. Depending on the type of administration console PC you use, the null modem pin-outs may vary. The following are appropriate connections:

CyberSWITCH to IBM ATCyberSWITCH to IBM PC

DCD	1	4	DTR	DCD	1	20	DTR
DSR	6	2	RCV	DSR	6	3	RCV
RCV	2	3	XMIT	RCV	2	2	XMIT
XMIT	3	1	DCD	XMIT	3	6	DCD
DTR	4	6	DSR	DTR	4	8	DSR
GND	5	5	GND	GND	5	7	GND
RTS	7	7	RTS	RTS	7	4	RTS
CTS	8	8	CTS	CTS	8	5	CTS

2.On the PC, execute the Manager software from diskette, or install the software on your PC’s hard disk and execute from hard disk. (1 MB of free space needed for installation.) Note that hard disk operation is more efficient.

Note: You do not need to change Carbon Copy’s port parameters. The default values are sufficient for null-modem connection.

Powering On:

1.Verify that the line voltage select switch is set for the correct AC input power source.

2.Plug the standard power cord into the CyberSWITCH’s AC input power socket.

3.Ensure that the POWER-ON button on the CyberSWITCH is in the OFF position.
