due to some Exchange server problems we've been having I've been asked to replace all the ethernet cables (UTP Cat 5e) that connect the servers to the switch (Cisco 6509). Each server has 2 NICs and each one of these connections to the switch goes from patch panel to patch panel (i.e. there's 3 cable lengths between server and switch). There would be 18 calbes to replace in total.
The cable lengths are only about 15 metres or so in total. I was wondering if this is necessary. The server team are clutching at straws as they don't know what's causing the problem. There are no errors on any of the switch ports connecting the servers to the 6509.
Basically my question is this, if there are no errors of any type on a switch port is there any possibility of a problem with the cabling? Do cable problems always generate interface errors? If the fact that there are no errors means that the cabling is definitely fine then I can tell them that there's no point in replacing the cables.
