HP 1420-24G-2SFP Switch FO connection related problem

[mks412]

I have a  HP 1420-24G-2SFP Switch. It has 2 FO ports. can i use these two FO cables from these  FO ports to connect to a similar switch FO ports.whether it will create any data loop and create any problem or  my system network will be healthy.

To use both SFP Interfaces as uplink(s) to a same Switch and concurrently avoid loop you need to setup them as part of an aggregated interface (Port Trunking, AKA LAG Link Aggregation Group), that must be done on both ends in a equal way (same settings).

Since the HP 1420 isn't a managed switch - namely it is unmanaged and plug&play - I seriously doubt you can manage any Port Trunking feature (indeed it is not a supported feature if you check Switch's QuickSpecs)...exactly because, at higher level, you can't manage the switch as well...so you're stuck and, at best, you can use only one SFP Interface - per Switch - for the uplink you want to setup (no loop).
