Cisco Systems Cisco 12008 manual GRP Console Port Signals, Pin Signal Direction Description

Connecting Route Processor Cables

Note You must provide the EIA/TIA-232 cables to connect the terminal to the GRP console port or other devices to the auxiliary port. Cisco Systems does not provide console and auxiliary port cables; cables are available from other vendors. For compliance with GR- 1089 (intra-building surge), you must use shielded cables on the GRP console and auxiliary ports.

Because the connectors on some standard cables are tall enough to interfere with the front covers installed on the card cages, Cisco includes a lower-profile cable adapter that permits you to connect a flat cable with modular RJ-45 plugs to the GRP console port.

For console and auxiliary port pinouts, refer to Table 3-1 and Table 3-2, respectively.

GRP Console Port Signals

Both Data Set ready (DSR) and Data Carrier Detect (DCD) signals are active when the system is running. The console port does not support modem control or hardware flow control. The console port requires a straight-through EIA/TIA-232 cable. Table 3-1 lists the signals used on this port

1	GND	–	Ground
2	TxD	Output	Transmit Data
3	RxD	Input	Receive Data
6	DSR	Input	Data Set Ready (always on)
7	GND	–	Ground
8	DCD	Input	Data Carrier Detect (always on)
20	DTR	Output	Data Terminal Ready
