Howdy,

Lots of stuff common across the 5500 range so quite confusing.

All are Gigagbit edge ports with Comware v5 OS and are IRF (cluster/stack) configurable with the right (10Gb) modules in the back. IRF between common types i.e. all "5500EI" models. Very capable, a bit noisy, quite deep 42-46cm (?) so watch the cabinet depth. CX4 cables make them even deeper with bend radius .Types = Standard 24 and 48 port, POE+  24 & 48, and SFP (24?) options available. All are wire speed and have dynamic buffering capability.

As for the suffixes:

SI = Basic Routing i.e. Static & RIP, 10G option modules inc IRF stacking.

EI = Dynamic routing protocols (OSPF, BGP), VPN instances (VRFs) and MPLS MCE, 10Gb option modules, SFP version available. Single PSU with RPS option - SFP has dual PSU.

HI = dual Hot Swap PSU's, can do full 30W POE,  full MPLS/VPLS feature-set, built in SFP+ ports, in service software update capability

Not a lot of difference in street price between 5500EI fully loaded with 10Gb modules and 5500HI using DACs to stack. I'd buy 5500HI's all day long.

As for the "S" = Standard, E = "Enhanced" & H = "High Availability" - I thought...

Hope that helps.
