Step 6
Turn on power to the router by pressing the power switch to the ON ( | ) position.
On the Cisco MWR 1941-DC router, turn on power to the router by turning ON the DC power source at
the circuit breaker.
Step 7
Check that the CONN LED goes on, which indicates that the card’s serial port detects the WAN serial
connection.
Serial High Speed WICs
There are five Cisco serial high speed WICs (HWICs). This section describes the HWICs and tells how
to connect them to a network. It contains the following subsections:

4-Port Multiprotocol High Speed HWIC
The 4-port multiprotocol high speed HWIC (HWIC-4T) is illustrated in
Figure 37
. Protocols supported
are Async (SLIP), Async (PPP), HDLC, Bisync, and transparent.
