A6795A tachyon XL2

Q1 A6795A currently installed but not connected, displays "Topology is Unkown" in stm. When connected needs to be in Arbitrated Loop, is there a setting to alter Topology or is this Automatic?
Q2 Already answered as to whether the speed can be locked to 1 or 2 Gbps? - as it is Autosense speed depends on connection at other end.

Q1 & Q2 - its up to Brocade (or else vendor)
switch settings.a6795a itself supports autosensing (sets its speed 1gbit or 2gbit).It can't be locked.More details on vendor's (Brocade?) site for specific switch settings.

Re: A6795A tachyon XL2

It's fully automatic, topology and speed are determined by the card and driver themselves, there're no any switches/software to lock them.
If you use switch you can lock switch's port into quickloop (thus FC card will be working in provate loop) and if you have 2GB/s switch lock ort in 1GB/s mode (instead of 2GB/s or auto-negotiation).
More questions?
