12 Chapter 3 - Network Installation
Powering Up the Router
Power up any modem, CSU/DSU, or TA before powering up the router.
This allows the router to immediately sense whether its secondary inter-
face is connected. The exception to this rule is when connecting an
RS232 interface to a CSU/DSU. In such a case, you must power up the
router before powering up the CSU/DSU. At power-up, the router will
take approximately one minute to become visible to CompatiView.
v Note: If you want to use Telnet as a management method, you must
first configure an IP address into the router using an out-of-band
console, or reconfigure the IP address on an IP host or workstation on
the same Ethernet segment as the router. See Chapter 5 - Command
Line Management for more information.
