<br><font size=2 face="sans-serif">Hi,</font>
<br>
<br><font size=2 face="sans-serif">I am using Mellanox MHES18 HCA connecting
with Qlogic 9024 unmanaged switch. Sometime after system reboot I get 1x
link width on two ports between HCA and the switch. The cable is good.
It's supposed to be 4x, and usually after one more system reboot it will
go back to 4x. My question is, can I simply change the port's physical
state to polling and let it do link training again to get 4x link without
reset the HCA? Is it possible?</font>
<br>
