7G-6MGBIC-A
Changes
Installed 7G-6MGBIC(-A)
Symptoms
Expansion module not recognized
Uplink not being seen by local management
No connectivity through gigabit uplink
Continually reboots
"Empire Initialization Failed"
Won't boot
"Cnx Based Internal Serpentine 10/1000 Mbps PHY Lpbk"
"Function Name: lpbkDiag"
Cause
If a 7G-6MGBIC(-A) is improperly installed, a DFE switch either may not properly boot, or will not properly recognize the 7G-6MGBIC(-A) ports.
The following three sets of symptoms have been observed, though this should not be considered to be an all-inclusive list:
- The host switch fully boots, but the 7G-MGBIC(-A) ports are not listed in the results of a 'show port' command, and they do not function.
- The host switch enters a constant reboot cycle, with the error message
Empire Initialization Failed
- The host switch fails to fully boot, with the error sequence
Running Initialization Diagnostics... FAILED.
Device Name: Switch Ports
Test Name: Cnx Based Internal Serpentine 10/1000 Mbps PHY Lpbk
Test Result: Failed
Function Name: lpbkDiag()
Error Description: Timeout (loop=1, data=012, block=0, port=0, len=64).
Ucast pkt count error on MAC 2, port 0 (Rx=0, Tx=0).
Solution
If
any boot anomalies or 7G-6MGBIC(-A) functionality issues are seen, after recently installing a 7G-6MGBIC(-A) or its host DFE switch, check the installation of the 7G-MGBIC(-A):
- Remove the DFE switch from the chassis (using proper removal procedure 5036)
- Using ESD (electro-static discharge) precautions, examine the two rectangular black connectors where the 7G-6MGBIC(-A) connects electrically with the host switch's circuit board
- Ensure that these connectors are fully engaged and locked
- Ensure that the three securing screws are properly seated
- Reinstall the DFE switch into the chassis
