Chapter 1 Introducing the Cisco Application Deployment Engine 2130 and 2140 Series Appliance

Hardware Features

On the rear-panel serial (console) port, Pin 7 can be configured with a jumper located on the appliance motherboard. This jumper allows you to set Pin 7 to either Data Set Ready (DSR) or Data Carrier Detect (DCD) as might be required when using a serial port concentrator. The default jumper configuration selects the DSR signal, which conforms to the Cisco serial port standard.

Table 1-12 on page 1-14shows the rear-panel serial (console) port pinout description.

Table 1-12	Rear-Panel RJ-45 Serial (Console) Port Pinout
Serial Port Pin		Signal	Description
1		RTS	Request to send
2		DTR	Data terminal ready
3		TXD	Transmit data
4		GND	Earth ground
5		GND	Earth ground
6		RXD	Receive data
7		DSR or DCD1	Data set ready or
			Data carrier detect
8		CTS	Clear to send

1.A jumper block on the appliance motherboard determines whether DSR or DCD is routed to Pin 7. The appliance motherboard has the jumper block preconfigured with DSR enabled.

Serial (Console) Port Cables

Use the thin, flat, RJ-45-to-RJ-45 rollover cable and the RJ-45-to-DB-9 female DTE adapter (labeled TERMINAL) to connect the console port to an ASCII terminal or a PC running terminal-emulation software. Table 1-13lists the pinouts for the asynchronous serial console port, the RJ-45-to-RJ-45 rollover cable, and the RJ-45-to-DB-9 female DTE adapter.
