What means (2 LRM Capable) in 220 Series Description?


Hello, team,

"220-Series 48 port 10/100/1000BASE-T, 4 10GbE unpopulated SFP+ ports (2 LRM Capable), 1 Fixed AC PSU, 1 RPS port, L2 Switching with RIP and Static Routes, 1 country-specific power cord"

Does it mean that only two SFP+ ports could be used for 10Gb transceivers simultaneously?

Hi Ilya,I'm just going to guess, but I imagine it means of the four 10GbE SFP+ ports, only two of them can effectively power LRM optics.

there are 4 SFP+ ports. each is capable of 10G.
Issue is with LRM = consume a lot of energy and there are only two SFP+ ports what can deliver enough of energy for LRM.

hope it is easier to understand now.
