What GIG Modules

For the life of me, I cannot find what GIG modules I need to chain my 2950 to my 3650 when it comes in. I have dug through the whitepapars, etc and cannot find a reference. I was just wanting the gig ethernet model numbers. Fiber can be used later - or is it worth it now?

Re: What GIG Modules

Are you referring to Interface cards to connect the two switches via GigEthernet with Copper?

If so and assuming a short haul link, then for the 2950, you'll need a WS-G5483, and for the 3560, you'll need a GLC-T

Refer to the following document for the Gig Ethernet Transceiver compatibility matrix:

Re: What GIG Modules

hi i feel u can better look out for 1000BASE-SX or 1000BASE-LX/LH GIG modules.

on 3560 it will SFP type and on 2950 it will be of GBIC-based Gigabit Ethernet .

i think u better can check out for LX/LH module which is support in both the modules.

when it comes to fiber u can make use of multi mode or single mode here.

the connectors would be LC on one side which connects to 3560 and SC on the other which connects to 2950

the basic difference between SX,LX,ZX is the distance it can hold off the signal...

Re: What GIG Modules

If you interconnect adjacent machines via fiber, be aware of the minimum cable distance spec. For SFPs and GBICs it's 2M. Probably a similar restriction for Cat 5, but I don't know what it is -- dependent on the transceiver.
