all the ports of my new sw300 remain in the state of 'no_sync', i have checked all kinds of possibility but failed to figure out. So i am trying to upgrade firmware, who can tell me how and where to download latest firmware? However, any advice or suggestion for this problem will be a appreciated.

No_sync means port is receving light but out off sync, which i don't think will be resolved by an FOS upgrade.
What did you try anyway (steps command)
Can you post the output of switchshow and portshow off a afected port

Hi Dion, Thank you for your response.
Actually we have 2 new sw300, named sw-a, sw-b, and sw-b is abnormal while the other one (sw-a) works very well. If hba from host connects to sw-a, it will sync immediate with sw300 port and change to 'online' soon, but it will fail to sync if connects to sw-b. All the ports on sw-b remain in 'no_sync', and I have rebooted many times, even rebooted after removing all the sfps, but not any improvement. The health checks show hardware is good, and i remember sbdy has told me maybe fos imcompatible, so i'm trying to upgrade.
Here is the commands output:

given a number of ports in No_Sync, the first thing I'd check would be device connectivity.
What is connected to these ports?
What kind of SFPs your end devices use?
What kind of cables are used?
Are end devices configured already?
One common case for No_Sync is when your switch receives the signal but the other device does not.

emc cx front-end / qlogic hba ports connected to sw300.
sfps are from brocade, 850nm, 200,400,800_MB/s M5,M6 sw Inter_dist.
lc_lc fiber cable.
the other end devices are all configured.
Acturally, we can exclude external possibilities, 'cause, as i have mentioned, the same hba from a host will fail to sync with this sw, while working well if connected to the other good sw.
thank you for response.

okay then, let's get back to the roots. If you connect a patch cord to switch ports (say 1 and 2, creating a loopback), does it detect a loopback connection?
Could you compare fill word mode on this switch vs working one?
Note that there are two ports in the In_Sync state which means they receive light from another device, which is different from the rest of the ports.
Would you mind uploading supportShow from that switch?
More precisely, I'd like to have a look at the output of the following commands, among others:
