Hi,
I have just now plugged in a SFP into a new test setup (connectX-3 card) and plugged the other end of the fibre cable into a Cisco switch. Here's what the setup looks like right now by way of the self test -
# hca_self_test.ofed
---- Performing Adapter Device Self Test ----
Number of CAs Detected ................. 1
PCI Device Check ....................... PASS
Kernel Arch ............................ x86_64
Host Driver Version .................... MLNX_OFED_LINUX-2.3-2.0.0 (OFED-2.3-2.0.0): 2.6.32-504.el6.x86_64
Host Driver RPM Check .................. PASS
Firmware on CA #0 NIC .................. v2.32.5100
Firmware Check on CA #0 (NIC) .......... PASS
Host Driver Initialization ............. PASS
Number of CA Ports Active .............. 1
Port State of Port #1 on CA #0 (NIC)..... DOWN (Ethernet)
Port State of Port #2 on CA #0 (NIC)..... UP 1X QDR (Ethernet)
Error Counter Check on CA #0 (NIC)...... NA (Eth ports)
Kernel Syslog Check .................... PASS
Node GUID on CA #0 (NIC) ............... 00:02:c9:03:00:3c:98:40
------------------ DONE ---------------------
At this point you probably think - cool it works. Port one on the card does not.
If I move the SFP to port one (no cable plugged in) I immediately get a flashing green light\LED. So I looked up the manual. It states:
Green - physical link
• Constant on indicates a good physical link
• If neither LED is lit, then the physical link has not been established
mmmmmm
So what does a flashing green LED mean?
