Connecting 3750X-48T-S to 3PAR

[Patrick McHenry]

Hey,

I'm going to connect a 3750X to a 3PAR using 2, SFP-H10GB-ACU10M. I noticed that shorter distances are called 'SFP-H10GB-CU2M' - the "A" is missing in the name. Does

signify anything different?

Thank you

Hi, 

yes there is a difference. 

The longer cables (7 and 10 metres) are called Active cables. 

The shorter cables (1 to 5) are called Passive. 

The Active cables require an "internal boost" to support or push the signal from one end to another.
