Interconnecting Summit 48i and Summit 48si

Hello All,

Has anyone ever faced a problem with interconnecting
the above mentioned switches? There are ports 49 and
49R on the Summit48i but a single port 49 on the
Summit48si and I am not sure how the fibre cables may
be connected.

Please suggest.

Many Thanks.

Nitin

Just ignore the R ports on the 48i. Just connect cables from the 48si SFP
port to the 48i GBIC port making sure that TX goes to RX at the other end,
and it should work automatically.

The R ports are "redundant ports" and are not used if there is link on the
primary port. So basically the 48i can only have two working GBIC ports at
any given time.
