Chapter 3 - Network Installation
Connecting the Router to the Ethernet
If your twisted-pair hub is already in place, you can connect the router
to an active network without interrupting network activity. The router
must be powered off.
Connecting to Twisted-Pair Ethernet
Before connecting the router to twisted-pair cabling you need an
unshielded twisted-pair cable that is already connected to your
10BaseT-compatible twisted-pair hub.
To connect the router to the twisted-pair network, simply plug the
twisted-pair cable into the RJ-45 Ethernet connector on the back of the
unit.
Connecting the Router to a T1 Line
To connect the router to the T1 line, you need a four wire jumper cable
that is already connected to the RJ-45 jack which was installed by your
telephone company. The router must be powered off. Simply plug the
jumper cable into the RJ-45 WAN 0 connector on the back of the
MicroRouter 2250R.
Connecting a Line Device to the Secondary Port
The MicroRouter 2250R supports lower speed synchronous/asynchro-
nous operation over a secondary RS-232 connector (WAN 1). This port
independently supports the PPP and Frame Relay link protocols.
Connecting Devices to the RS-232C Interface
This interface -- WAN 1 -- can be used to connect to synchronous or
asynchronous line communications devices at rates up to 256Kbps
(sync), or 230.4 Kbps (async). Examples include modems, leased or
switched 56K CSU/DSU’s, and ISDN Terminal Adapters.

Note:
If connecting to a synchronous device such as a CSU/DSU,
the router must first be configured for synchronous operation before
connecting to the device. See Chapter 6 - Basic Configuration Guide
for configuration information.
You may select either dial-on-demand, always up (i.e., redial if down),
or leased line operation. This interface may also be set to receive ISDN
or switched-56 incoming calls.
To connect a device, first make sure that both units are powered off.
Then, simply connect the supplied RS-232 cable between the router and
the device.
