I have a 1720 that I bought used and a WIC-1DSU-T1 module (that I bought from different source) installed in the first slot. When I power it up, the AL light eventually turns red and stays red. The CD light is green, and the "WIC 0 OK" light is green. Another, apparently identical, WIC works fine in this router. I sent the WIC back once and the replacement is doing the exact same thing. Is there something that needs to be configured in the WIC to make it work with my router? Could it need a firmware upgrade or something?
 
Create a loopback cable to test the WIC-1DSU-T1. RJ-45 pins 1-4, 2-5 connection. Set the framing to esf and linecode to b8zs, wri mem, plug the loopback cable and see the status of the LEDs.
 
Could you do a show version and post the output? That router has two slots....what results if put in slot 1?
 
With the loopback plug connected, the CD light comes on and the AL light goes out.

When I remove the cable to the T1 line, the AL light on the working WIC glows solid amber. However, when I do the same on the non-working WIC, the AL lamp glows solid red. Does this mean anything to anybody?

Is there any way to see the status of the WIC through the console?

Can you post the output from show interface ?

Also....why is your config register set for password recovery.....should be 0x2102

 
Nice catch!! The reason we're doing all this is because the password was lost to the original router. We decided to get a second router up and running before blowing the password out of the original. How do I reset the register back to normal?

The following "show interface" output was taken after having a loopback connector installed for 5 days. The AL lamp is solid red. That should not happen, right? Do I have another bad WIC?

That is the output from fast ethernet 0 which is shutdown. Can you post output from show interface serial0?
 
Duh! I'll send you two versions, one with the T1 and one with a loopback connector.

When we plug in the T1, the AL light goes out for a second or two, then comes back on.
When we plug in the loopback, the AL lights goes out after a few seconds, stays out for several minutes, but eventually comes back on.
Our old WIC had a yellow AL light, but the new one has a red one. Why?

What is this connecting to on the other side? You most likely need to change the encapsulation to ppp.
 
By the way:

router(config)#config-register 0x2102

This will change it back to std boot.
 
Remember to shut the interface down and bring it back up after you change the encap.
 
We spoke with the people at Qwest and they want the encapsulation to be HDLC.
At this point I'm just struggling to figure out if this WIC is bad so I can return it to the vendor. If the ALarm light is on with a loopback connector installed, what does that indicate?
 
Can you please post output from sh run...particularly the output of the config of the serial interfaces.....something caught my eye that concerns me......look at the bandwidth from the show interface. It reads 1536 which I recently ran into a problem with qwest. 1536 usually indicates AMI coding(robbed bit format) and should be 1544 if b8zs. Qwest had a bad niu at there CO that was supposed to automatically switch the line coding but was not functioning properly.
 
If you have a second wic you can test them by making a T1 xover cable and connecting them. The pinout is:
1 4
2 5
4 1
5 2

Configure both interfaces the same, bring them up, then connect the cable. If wics are good should only see green light on both.



Also double check with qwest as to the line coding they need.
 
I can get you that output when I go in there tomorrow afternoon. But, I keep going back to this fact: I have another WIC that I can plug in to this router and it works perfectly with no configuration changes. So, that means that the WIC is bad, or there is something I need to configure on the WIC, correct? Is there anything on the WIC that can be configured? Firmware? The only difference I can see between the two devices is that one has a red AL lamp and the other is amber. Anything else I should check? Would you like to see a show inferface with the good WIC? With or without loopback connector?
 
It does sound like the wic...some things just dont seem to make since though....like the 1536 bw....would not hurt to see the output both ways with the other wic for comparison. Would also suggest to get 12.3 IOS...12.1 pretty old.
 
wiley1, First check to see if the WIC card you have is a WIC-T1 or a WIC-T1-V2 (Version 2).

If it is a Version 2 card you will need to upgrade the IOS on your 1720 router to 12.3 (provided you have enough memory for it).
