Fibre Link Down [SOLVED]

[gmiller]

Hi Folks,

 

First day back in after holiday and yes you guessed it straight into problems.. welcome back!

 

A lot of client pcs cannot connect to the network. Traced it to the switch, netgear GS748TS. On the switch it looks like one of the fibre links is down. I have disabled and reenabled the port, swapped over the modules and it appears to be one of pair fibre cables, which will be fun to trace as its an old building and it goes up stairs!

 

Anyway. my question, why would some clients connect to the network ok and get an ip address ok that are patched in to this switch ghile others wouldnt? For example in the library there are 7 pcs. 2 get an ip and 5 others dont. would the fibre link being down have this kind of impact? I would have thought, the clients would have continued to pick up a connection but the speed would be impacted as data is going over one pair instead of the two pair?

 

I dont get why some ports\clients are ok and others are not. Any suggestions? Please enlighten me as switching and fibre are not my strong points..

 

Thanks

Miller

Well, what's on the other end of this broken fibre?

[gmiller]

the fibre on this switch links to the main core switch, tracing the connection on the switch (an hp 4104 gl) the fibre at the other end reports dead aswell.

The fibre issue was not the cause of the problem. DHCP problem was!.. Restarted the dhcp service, all clients now being allocated an ip address..
