Chapter 6 Configuring the MWR 1941-DC in a Cell Site DCN
Before You Begin
Note
If you skipped
Chapter 3, “First-Time Configuration,”
and you have never configured a Cisco router,
go back to that chapter and read it now. The chapter contains important information you need to
successfully configure your router.
Before You Begin
Before you configure the MWR 1941-DC in a Cell Site DCN, please note the following:
•
Cisco IOS Release 12.2(15)MC1a or later “mwr1900-is-mz” image must be installed on the Cisco
MWR 1941-DC router.
•
When using the NM-16ESW with the MWR 1941-DC router, shielded cables are required and IP
phone inline power is not supported.
•
When using the 1-port T3/E3 network module (NM-1T3/E3) in your MWR 1941-DC router
configuration, note that E3 mode is not supported with Cisco IOS Release 12.2(15)MC1a.
•
Network Time Protocol (NTP). NTP must be configured. The Cisco MWR 1941-DC router uses
NTP to maintain a clocking source for the proper time stamping of system messages and log files.
•
Redundancy—Standalone Mode. The MWR 1941-DC router must be configured to operate in
standalone mode. The standalone option must be configured from redundancy mode. To manually
set the relays to open or closed, do the following starting in global configuration mode:
Step 1
Enter redundancy mode.
Router(config)# redundancy
Step 2
Enter the y-cable mode.
Router(config-r)# mode y-cable
Step 3
Specify that the router is to be used as a stand-alone device. This command closes the relays.
Router(config-r-y)# standalone
Step 4
Exit y-mode configuration mode.
Router(config-r-y)# exit
To verify the status of the relays on an MWR 1941-DC router, use the
show controllers
command.
Timesaver
Before you begin configuring interfaces, disconnect all WAN cables from the router to keep it from
trying to run the AutoInstall process. The router tries to run AutoInstall whenever you power it ON,
if there is a WAN connection on both ends and the router does not have a valid configuration file
stored in nonvolatile random-access memory (NVRAM) (for instance, when you add a new
interface). It can take several minutes for the router to determine that AutoInstall is not connected to
a remote Transmission Control Protocol/Internet Protocol (TCP/IP) host.
