Hello, I aquired a couple of antminers s3+ an one is working fine but the other is not

the log says:
Can anybody help me please

Make sure network is set to DHCP .... also what firmware are you running (you can get this from the intial web UI page when you log in)
I am using Load: 0.06 0.10 0.07 | Auto Refresh: on and DHCP is on
Go to status - overview for the firmware date ...
Can you also be more explicit about the "not working". Is it not hashing at all or is it not hashing well?
Ok sorry, this is what I got
Firmware Version Tue Aug 26 10:43:10 CST 2014
Kernel Version 3.10.12
By not working I mean that I plugged it, pointed it to my pool, tarted to mine for like 10 seconds and then started to beep.
After that I get no hash at all and the page system->miner status shows no information available
