SFP question

[allanc16]

Hello we have the following switch that needs to be replaced:

WS-C3750G-12S

SWITCH#sh int g 1/0/1 | inc Base
Full-duplex, 100Mb/s, link type is auto, media type is 10/100/1000BaseTX SFP
SWITCH#sh int g 1/0/2 | inc Base
Full-duplex, 1000Mb/s, link type is auto, media type is 1000BaseLX SFP
SWITCH#sh int g 1/0/5 | inc Base
Full-duplex, 1000Mb/s, link type is auto, media type is 1000BaseLX SFP
SWITCH#
SWITCH#sh int g 2/0/1 | inc Base
Full-duplex, 100Mb/s, link type is auto, media type is 10/100/1000BaseTX SFP
SWITCH#sh int g 2/0/2 | inc Base
Full-duplex, 1000Mb/s, link type is auto, media type is 1000BaseLX SFP
SWITCH#
SWITCH#sh int g 2/0/5 | inc Base
Full-duplex, 1000Mb/s, link type is auto, media type is 1000BaseLX SFP

We are going to purchase 1 WS-C3650-24PS

1. Based on the output from the 3750 I have 6 SFPs connected to that switch, am I correct? 2 for regular UTP and 5 for Fiber?
2. Can I use these same SFPs on the new switch?

Hi,

WS-C3750G-12S has 12 fiber ports and WS-C3650-24PS is a copper switch with 4 1Gig fiber uplink ports. Is that what you are trying to do or you are looking for a 3650 fiber switch?

Can you clarify?

#1 Yes, it appears you have 6 SFPs, 4 fiber (not 5) and 2 copper.

#2 Generally, SFPs will work on other switch SFP or SFP+ ports.

As Reza notes, your selected 3650 only supports 4 SFP ports, but you should be able to connect the copper SPF links to directly to the 3650's copper ports (w/o the copper SFPs).
