Note: TheMicroRouter 1250i RS-232 interfaces require that your
asynchronousline communications device be set to supply the RS-232
DCDsignal when a connection has been made. Asynchronous RS-232
deviceshould be set to provide DSR.
Note: The MicroRouter1250i includes aspecial cable to facilitate
connectionsto RS-232 line communications devices. This cable
includessupport for several asynchronous and synchronous control
signals. Off-the-shelfcables generally do notsupport these signals.
Connecting an Out-of-Band Management Console
Ifyou wish to connect an out-of-band management console, use the
suppliedcabl e and connect to the Console interface on the back of the
MicroRouter1250i. Youcan use a dumb terminal or a computer
equippedwith VT100 terminal emulation.
Thed efaults ettings for theC onsoleinter faceare VT100 terminal
emulation,9600 bps, 8 bits, no parity, 1 stop bit,no Flow Control.
Powering Up the Router
Powerup any modem, CSU/DSU, or TA before powering up the router.
Thisallows the router to immediately sense whether its secondar yinter-
faceis connected. The exception to this rule is when connecting an
RS232interface to a CSU/D SU. Insuch a case, you must power up the
routerbefore powering up theCSU/DSU. At power-up, the router will
takeapproximately one minute to become visible to CompatiView.
Note:If you want to use Telnet as a management method, you must
first configurean IP address into the router using an out-of-band
console,or reconfigure the IP address on an IP host or workstation on
thes ame Ethernet segment as the router. See Chapter 5 - Command
Line Management for moreinformation.
