ICX 7250's & ICX 7450's
« on: May 11, 2016, 06:55:28 PM »
Interesting.  We were ordering some new user switches to replace older gear that is breaking down more and more often.  We were looking at the ICX 7250 and ICX 7450's switches.  The 7450's were nice with 2x40Gig dedicated stacking ports on the backs of the switches and pluggable modules on the front for different port configurations.  Plus they could hold a second power supply right in the switch for redundant power supplies and run PoE+ on 48 ports.  The 7250's are their much cheaper entry level enterprise switches.  No dedicated stacking ports, you use the 10Gig SFP ports on the front to stack the units and those 10Gig ports require licensing to run at 10Gig.  No second power supplies on-board, you need an external RPSU that would rack in below the switches and connect via a cable.  It can do PoE on all the ports and/or a mix with PoE+ on half the ports.

Of course I wanted the 7450's.  That's not what was ordered of course.  :(

As a side note, it seems that the buffering on these 7250/7450's is such that they shouldn't use their edge copper ports as uplink ports to other infrastructure gear.  Our SE with Brocade is adamant that the edge ports should not be used that way.  He says the SFP ports have 3x the buffering of the edge ports, so those should only ever be used for a LAG back to the core.
