Configuring Administrative Access, System Timing, and Startup Settings
Making the initial administrative connection
Storing enough configuration information to restart the unit after clearing
nonvolatile RAM (NVRAM)
Note
All connections that are illustrated in this section depict the Stinger MRT 23.
Connections for the Stinger MRT 19 are identical, except for the location of the
connectors on the front of the chassis. Connector locations for both models are
shown Chapter 2, in Figure 2-3 and Figure 2-4.
Making the initial administrative connection
The serial port of a Stinger MRT is used for initial configuration from a console
device, or to reconfigure the unit from a console after NVRAM has been cleared.
After configuring the unit initially, you can connect as follows for dial-in
administrative access:
Connect an external modem to the serial port. (See "Connecting to and
configuring an external modem" on page 6-11.)
On a model MRT-AD-36S-56K unit, connect the internal modem to an analog
POTS line. (See "Connecting to and configuring an internal modem" on
page 6-12.)
For other types of administrative connections, see "Additional administrative
connections and configuration" on page 6-9.
Figure 6-1 shows a cable connection from the Stinger MRT to a console terminal.

USE OF
To connect the console terminal to the Stinger MRT, connect one end of a shielded
straight-through cable to the CONSOLE port on the chassis. Then connect the other
end of the shielded straight-through cable to the serial port on the console device.
The CONSOLE port on the Stinger MRT consists of a female DB-9 connector.
Examine the serial connector of your PC or dumb terminal to ensure that your
shielded straight-through cable has the proper connectors. If needed, you can use
DB-9-to-DB-25 converters or gender converters to complete this connection.
For detailed information about the pinouts on the CONSOLE serial port, see
"CONSOLE port and cable pinouts" on page C-1.
