Hi Experts

I have cisco 6509 with the following modules.The issue i am facing is that the LR optics are not lighting up.As per the software advisor i tried the following software images.The SR modules within the same chassis works.The issue is there with my other switches like cisco 4900M,Cisco 3750-E all of which have the LR modules and they dont lit up whereas the SR does.Kindly help me out.

  • Cisco Employee,

I suggest you not to look at it. This is a powerful laser and it can damage your eye. Also, the wave length is very small (1310nm), you might not able to see if if you decide to look at it. The best way to do it is to use an optical power meter to check if there is any power coming out from the XENPAK.

jerry

The table said Minimum Software Release Required. Any IOS above that in the same train, SX, will support that module.

Your IOS

What is the issue? The remote end, XENPAK-10GB-LR (or any 10G-LR) with SMF, is not detecting the link or you are still trying to look at the light?

Hi Jeye,


the issue is the 6509  XENPAK-10GB-LR - link is not coming up while connecting to 4900 cisco XENPAK-10GB-LR in which is located in one of the HUB-Rooms

Just for a quick L1 test, you can use a single strand SMF and connect the same XENPAK TX and RX together to check if it is working or not. The good XENPAK should give you a green light if you look at the front when connecting the TX and RX together.

I would follow Jerry's advice and not try to look at the light.


Jerry, does the loopback test you proposed require the use of an attenuator? I think I see that in the asterisks of Table 1 in the document included in your first post.

Hi Jerry,


Looks like my eye got confused with the number of asterisks. I guess me trying to look at the light wouldn't have been more successful, even if it wasn't dangerous.


Thanks,

Maria

Once again, I will not look at it and it is your choice to look at it. Hence, I will not confirm if you can see it or not. I will use optical power meter to check the power of the XENPAK.


Also, 12.2(33)SRA is for 7600's, the module is detected with your IOS software and it should be fine. The WS-X6704-10GE is supported since IOS 12.2(17a)SX or CatOS 8.1.2.
