Stacking Switches

[nathan]

Just looking into some netgear gs752tsb stackable switches, am i correct in saying that you have to use SFP's to stack them?

 

I'm looking at the ones listed on broadband buyer > NETGEAR GS752TSB ProSafe 48-Port Smart Stackable Gigabit Switch w/ 6x Combo SFP Ports

 

I'm just trying to work out how the stacking works, how do you link them together to provide the high availability?

 

As you can tell, i'm pretty new to stackable switches.

having quickly looks at the manual http://www.downloads.netgear.com/files/GDC/datasheet/en/GS728TS-GS728TPS-GS752TS-GS752TPS.pdf

4 of the SFP's are used for stacking if im reading it correctly.

id imagine if 4 SFP are used they work as 2 pairs.

So if there are more than 2 switches how do link together? in a daisy chain? If that's the case and one switch fails would that break the daisy chain?

[hallb15]

There are two 2.5Gb SFP ports on each switch so you can daisy chain them, but yes if one switch fails, then any above it in the stack will also fail.

You can stack up to 6 switches, using the netgear direct SFP cable AGC761.

There's more info on this FAQ, GS7xxTS-TPS FAQ's | Answer | NETGEAR Support

brill, thanks

I can't attest to these specific switches, but usually you create a ring on stacked switches, so the top of the stack connects to the bottom of the stack. that way if one switch fails the stack can still operate

 

ie SW1>SW2>SW3>SW4>SW1
