Reference Information

Reference Information

Following is reference information for console and auxiliary port pinouts, replacing DRAM SIMMs, configuring the software configuration register, recovering a lost password, and using the front-panel PCMCIA slots for additional Flash memory.

Console Port Signals

The console port on the RSP7000 is an EIA/TIA-232, DCE, DB-25 receptacle. Both DSR and DCD are active when the system is running. The RTS signal tracks the state of the CTS input. The console port does not support modem control or hardware flow control. The console port requires a straight-through EIA/TIA-232 cable. Table 2 lists the signals used on this port.

Table 2 Console Port Signals

Pin	Signal	Direction	Description
1	GND	–	Ground
2	TxD	<—	Transmit Data
3	RxD	—>	Receive Data
6	DSR	—>	Data Set Ready (always on)
7	GND	–	Ground
8	DCD	—>	Data Carrier Detect (always on)

Auxiliary Port Signals

The auxiliary port on the RSP7000 is an EIA/TIA-232 DTE, DB-25 plug to which you can attach a CSU/DSU or other equipment in order to access the router from the network. Table 3 lists the EIA/TIA-232 signals used on this port.

The asynchronous auxiliary port supports hardware flow control and modem control.

Table 3 Auxiliary Port Signals

Pin	Signal	Direction	Description
2	TxD	—>	Transmit Data
3	RxD	<—	Receive Data
4	RTS	—>	Request To Send (used for hardware flow control)
5	CTS	<—	Clear To Send (used for hardware flow control)
6	DSR	<—	Data Set Ready
7	Signal Ground	–	Signal Ground
8	CD	<—	Carrier Detect (used for modem control)
20	DTR	—>	Data Terminal Ready (used for modem control)
