I am looking at going over to a gigabit LAN but I'm not sure about my cabling. I know that Cat5 is no good for gigabit and cat5e is the minimum, but my question is how can I tell if my current cable is cat5 or cat5e?
Some of my fly-leads have cat5e printed on them but some don't explicitly say cat5 or cat5e. And my installed cable?????
To be sure there are only two ways I know of:
1) Get someone with the appropriate test gear to test your cabling (I presume you could replace the leads you are unsure about).
2) Get the product numbers from the cabling and look it up.
With regard to suggestion #2, not fool-proof, if you have it terminating in wall plates the cable can be higher specd than the termination quality.
Of course you could alway lemon engineer, get your new switch, plug it all in and see what sort of auto negotiation and ultimately throughput you get!

5e works good for me, I am trying to avoid 5 for gigabit as it is clear from some testing results done for VMWARE and they are not good, as they and EMC told me when I have asked about iSCSI and cabling. We use CAT6 at work.
CAT6 would be ideal, but I have 5e so I use them. How long are your cables?

Hopefully theres a cable guru here who can help.
GlenR...
Cat5 can operate up to 100Mhz
Cat5e (e stands for enhanced) can operate up to 350Mhz
Cat6 can operate up to 600Mhz
Now all they gotta do is make equipment that can fully utilise these operating capabilities. FYI, they currently can only utilise the Cat5... great marketing me thinks...

I just ducked over to Wikipedia to look at cable categories and giabit LAN. An article on gigabit LAN said the specification allowed gigabit over Cat 5, the one on cable categories said Cat 5 may be unstable for gigabit.
Don't you love it when there is agreement on technical specs?
