Lights on the switch

[Conan Kelly]

Hello all,

We have a little LinkSys workgroup switch (5-port) mdl # EZXS55W. I having trouble finding documentation online for it.

We have a scanner from a Kyocer All-in-one office printer/copier plugged into port 1, my desktop in port 3, and then the main switch
in the server room plugged into the Up-link/port 5. The "Full/Col" light on port 3 is lit up steady orange. I know "Col" stands
for collision. What does "Full" stand for?

Should I be concerned that this light is lit?

"Full" means that the connection is using full duplex, so it can send
and receive data at the same time. That's better than the other
possibility, half duplex. You should be pleased.

Steve,

Thanks for the feed back.

If that is the case, then there is full duplex between the workgroup switch and my computer, but then it must be halfduplex between
the workgroup switch and the main switch. That doesn't seem very good.

How do I know when the light means Collision instead of Full? Is it a different color? Is it blinking? How?

Thanks again for all of your help,

Conan

You're welcome, Conan.

The FD/Col light is on when the corresponding port has a full duplex
connection, and it blinks when there are collisions.

What make and model is the main switch? Any chance that it's actually
a hub, not a switch? Hubs only connect in half duplex.

How long is the cable between the workgroup switch and main switch?
If it's too long or improperly wired, the cable might only support
half duplex.

Steve,

Thanks again for all of your help.

It is not a hub. It is an HP Procurve Switch 2626 (J4900B).

This is a small office (6 users) and I sit right across from the room being used as our server room. the lenght of the cable is
probably less than 20 ft. I'll have to bring in my wire map tester to see if it is wired correctly.

Is there any way that ports on the switch can be programed to connect in half duplex? I installed 3 new drops in my bosses office
and when I first connected these drops to ports 1 & 2 on the switch, the lights on the switch lit up but I couldn't access the
internet/network from the computer/VoIP phone I was connecting. As soon as I plugged into 2 other ports, everything worked fine.

Thanks again,

Conan

An inexpensive switch like the Linksys EZXS55W has no programming
options. The HP switch might -- check its documentation:
