I have a Dishnetwork 500 system. I have 4 receivers hooked up to a SW64 Switch.

All of a sudden my Dish 6000 receiver fails to recognise the switch. All the other 3 5000 receivers are working fine.

Dishnetwork sent out a man to troubleshoot who said the receiver was bad. So, I got a new 6000 receiver.
The new receiver too cannot detect the SW64 switch. On every attempt it detects a different switch.

Can anybody help me with my problem?

Have you tried moving the 6000 to another room that works on another IRD? You can also have this problem if you don't have latest firmware. On the info screen it will tell you the firmware version. Check with Dish to see if that is the most current version. It gets updated from the stream. If it needs an update make sure the reciever is off (led off) and in the menu tell it to accept upgrades without your permission. Give it about a half hour then turn it back on see if that helps. It will not upgrade unless you have it powered off. If that doesn't work and moving it to a known working location does then it would be a bad port on the switch,cable to that location or cable end.

Also if you are hooked up to all 3 birds don't put a check on the Dish 500 in the menu. If you are only seeing 2 sats then go ahead and check Dish 500 then do your check switch.

Thanks for the advise. I will take the steps you suggest and pass on the results
