We have a stack of three WS-C3750-48TS-S with GLC-LH-SM= in it. We
must connect WS-C2960G-48TC-L to this port(s). The question is to get
a code for all equipment items to make this connection. Any help is
appreciated.

Serhiy.

P.S. Sorry for my English ;-)

As far as I remember, it's something like 12.2...

It's not ordered yet.

That is what I want to know: 1) model of SFP for WS-C2960G-48TC-L
and 2) model of cable to
connect'em

Thank you.

How afar apart will these switches be located ?

Are you using single-mode fiber to connect ?

In a neighbouring racks (have two racks only).

Not shure about it, but I can provide you with parts numbers for
SFP and Fibers used to connect another links:
SFP Prod.# GLC-LH-SM=, P/N: 30-1299-01, CLEI P/N: CN8ID42AAA
FO Patch 2xLC-2xFC 9um, UPC 3m, P/N: R126121

Thank you.

Serhiy.

my understanding is that the WS-C2960G-48TC-L has 2 dual-purpose ports
( for uplinks)
i.e. two RJ45 ports that are "paired" with two SFP ports - only one
of the two-paried ports can be used at a time.

so you should be able to copper cable the 2960G (CAT5E or better
cabling) which would mean you would get two copper SFP's for the
3750's if you want to have two links between the 2960 and the 3750

if you want to use fiber then you would use short-haul (SX) SFP's -
multimode would suffice for 1GE link

If you have a Cisco SE discuss with him/her or distributor SE
