Network Connection Considerations
Console Port Connections
Each access server system includes an EIA/TIA-232 (RJ-45) console asynchronous serial
port. This port connects to a terminal using an RJ-45 cable and an RJ-45-to-DB-25 adapter.
Depending on the cable and the adapter used, this port will appear as a data terminal
equipment (DTE) or data communications equipment (DCE) device at the end of the cable.
To connect to a console terminal, use an RJ-45 rollover cable with a female DTE connector
(labeled “Terminal”) for connection to the console port. For detailed information on
installing the console terminal see the section “Connecting to the Console Port” in the
chapter “Installing the Cisco 2500 Series Access Server.”)
The appendix “Cable Specifications” lists the pinout for the console port. The default
parameters for the console port are 9600 baud, 8 data bits, no parity, and 2 stop bits. The
console port does not support hardware flow control or modem control.
Auxiliary Port Connections
An EIA/TIA-232 (RJ-45) auxiliary asynchronous serial port is included on all access
servers. This port can connect to a modem for remote maintenance, or terminal services.
Use an RJ-45 rollover cable with a male modem (MMOD) adapter (labeled “Modem”) for
this connection. For detailed information on connecting devices to the auxiliary port, see
the section “Connecting a Modem to the Auxiliary Port” in the chapter “Installing the Cisco
2500 Series Access Server.” See the appendix “Cable Specifications” for the pinout for this
auxiliary port.
Network Connection Considerations
This sections describes important cabling information that must be considered before
making your network connections. The Ethernet or Token Ring ports are used to connect
to a LAN; the synchronous serial ports are used to connect to a WAN; and the asynchronous
ports are used to provide remote access to the access server.
Ethernet Connections
The Ethernet port is located on the left of the rear panel of the access server. The port is
labeled AUI. Use an Ethernet transceiver to connect the access server directly to the
network.
