1720 won't boot and question about simulating WAN using T1 WICs

wweboy

Hey everyone,

I was given some equipment from work to help with labbing. I was able to flash the proper .bin file to two of the three routers. I did the final router and I flashed it and it all seemed to go good but I can't get to the "Press RETURN to get started!" menu

Hitting enter does nothing I can get into ROMMON but confused as heck as why I can't get past this point. Also all 3 routers have 1 or more T1 WICs is there anyway to use them rather then purchasing some serial WICs and buying hte cables to simulate wan connections?

Thanks everyone for your assistance. Also I hope this isn't posted in the wrong section. If so please move.

My first thought was that maybe 32 MB of DRAM was too little, but Cisco's Feature Navigator says 32/8 for your IOS, so I don't know. But, as for the T1 WICs, you can absolutely use them for creating WANs. You would connect them together with a T1 Crossover Cable. You can either buy one on eBay (They're cheap compared to Serial Cables) or make your own. It's just like a regular crossover cable except you reverse the Orange and Blue pairs (1,2 and 4,5) instead of Orange and Green (1,2 and 3,6). You can google for a pinout diagram.

Configuring is relatively easy:

R1(config)#int s0/0/0
R1(config-if)#ip address 10.0.0.1 255.255.255.252
R1(config-if)#service-module t1 timeslots 1-24 (1-24 = Full T1/1.544 Mbps; You could use less timeslots for a Fractional T1/64 Kbps and up)
R1(config-if)#service-module t1 clock source {line | internal} (line = DTE and internal = DCE)
R1(config-if)#no shutdown

You can also set the encapsulation to PPP, Configure Frame Relay, anything you would normally do for Serial.



The two longer cables from the 2821 to 2 x 1760s are T1 Crossovers (that I made myself) from a WIC-1DSU-T1 V2 (2821) to a WIC-1DSU-T1 (1760). They function just as if I had used a back-to-back serial cable between two WIC-1Ts.

You could try reinstalling the old IOS from ROMMON.

ROMMON 1>IP_ADDRESS=192.168.1.201
ROMMON 2>IP_SUBNET_MASK=255.255.255.0
ROMMON 3>IP_DEFAULT_GATEWAY=192.168.1.1
ROMMON 4>TFTP_SERVER=192.168.1.5
ROMMON 5>TFTP_FILE=c1700-y-mz.123-1.bin
ROMMON 6>tftpdnld

Obviously, you would substitute an IP Address, Subnet Mask, TFTP Server, and Default Gateway on your network. You would also substitute the image you want to install for TFTP_FILE. Connect Fa0/0 to your home network before starting and make sure you have a TFTP Server running with a copy of the IOS image you want to install in the root directory.

Thanks I actually did what you asked and the print out is what happens after it tries to boot up. I'm going ot look into the T1 cross over cables that is awesome I won't need to purcahse much.

Thank you again.
