What is the best way to connect two HP 2530-48G (J9775A) switches using the SFP ports? The switches are a few inches apart in the same rack. Is there a SFP direct attach cable?

  • The cable required depends on the particular SFPs you are using, and the SFPs must match on each switch.

Checking the webpage of accesories for HP 2530-48G (J9775A) I could not find any Direct Attach Cable for this switch, neither 10G fiber based SFPs.

Among the SFPs compatible with this switch:

  • If you want to use the SFP ports for interconection and would like/need to avoid optical fiber cables you can use the HP X121 1G SFP RJ45 T Transceiver (J8177C) which is 1G and suitable for your distance.
  • If you don´t have a restriction forcing you to avoid fiber links, take into account that HP X121 1G SFP LC SX Transceiver(J4858C) is a bit cheaper than the copper one (at least in list price for the USA) and also suitable for your distance

You can use whatever pair of SFP's you want (SR, LR, T.)

Direct Attach Cables do exist, but I'm only aware of ones for 10/40Gbe -- i.e. SFP+.
