Solution
M0 OFF OFF
No power. Board not inserted correctly.
1. Remove and re-insert board.
2. If board does not power-up after re-insertion,
try a different slot. If board continues to fail
in the new slot and the problem does not
affect other boards running in the chassis,
return the Ethernet Switch Blade board for
repair.
M1 ON ON
No Communication with the Shelf Manager. Make
sure the hot swap ejector handle is securely closed.
The Hot Swap LED may remain lit or blinking if
awaiting permission to activate from the ShMM
If the Hot Swap handle is closed, retrieve the Mstate
information from the ShMM. Use the tips in the
Accessing the ShMM section below to determine if
other FRUs are also encountering difficulty (could
indicate a chassis-wide failure of the IPMB bus)
M2 LONG
BLINK
OFF If the switch has reported critical sensor data for
temperature or voltage, the ShMM can prevent the
switch from booting. To determine if the critical
sensor events persist, it may be necessary to alter the
rules enforced by the ShMM to allow the switch to
boot (receive back-end power). See Accessing the
ShMM section, below, for more information
M3 OFF OFF
Check the Shelf Managers to see if the voltage and
temperature sensors are within threshold (see the
Accessing the ShMM section below for how to
retrieve these values or detect critical thresholds
exceeded events), this indicates an internal hardware
fault and inoperable IPMC. Replace the switch.
Follow the other troubleshooting tips in the
Accessing the ShMM section below to determine if
exceeded thresholds are specific to the switch, or
might indicate a chassis-level problem (if other FRUs
are also reporting similar events).
M4 OFF ON
Switch Operational State. Try connecting into the
Ethernet Switch Blade User's Guide release 3.2.2j page 151
