Choosing modules and transcievers for 3Com SuperStack 4 Switch 5500G-EI.

[Boris-Emelyanov]

Hi everyone!

I have a small network mainly built on 3com 5500. Uplinks are 10G optical links.

Now i have to add a new segment to lan, and i allready have a brand new 3com 5500 (3CR17255-91).

I chose an appropriate connectivety module: Switch 5500G-EI 2-Port 10G Module (3C17268) or HP 2-port 10GbE XFP E5500 Module (JE085A).

The problem is, that i dont  know which transcievers to use. 

On existing 5500 i type 

> display interface TenGigabitEthernet 1/1/1
…............
Port hardware type is XFP_10GBASE_LR
…......................

 But then

>display transceiver-information interface TenGigabitEthernet 1/1/1
…........
Serial Number          : 3CXF96L003

….........

  In description to 3CXFP96 on hp.com i find  : ER XFP TRANSCEIVER, but display interface says: 

XFP_10GBASE_LR

So....  96 - ER or LR?   What should i take to make a new segment compatible with others?
