2.8.5 MMC Firmware Upgrade Procedure
The upgrade procedure is compliant to PICMG HPM.1. MMC Firmware upgrades can be done by using
IPMITOOL from
sourceforge from the front board or remotely on the chassis. It has been designed to upgrade
through any IPMI interface without payload impact.
2.8.6 Boot Block Upgrade Procedure
Type the following to perform MMC firmware upgrade
ipmifwu -fb -P /dev/ttyS1 -M rtm -p
2.8.6.1 Hot-Swap Process
The RTM8050 has the ability to be hot-swapped in and out of the front board. The onboard MMC manages the
RTM's power-up and power-down transitions. The list below illustrates this process for power down request.
1 Ejector latch is opened. HOT_SWAP_PB# assertion. MMC firmware detects the assertion of this
signal.
2 MMC sends "Module Handle Open" event message to the front board. The corresponding M state of
the front board moves from M4-> M5.
3 The front board moves from M5 -> M6 if the SHMC grants the request. The front board IPMC sends
the FRU control requesting quiesced state to the RTM.
4 The firmware deasserts payload power and sends "Module Quiesced" event message to the front
board where it transitions from M6 to M1 state.
2.8.6.2 Hot-Swap LED
The RTM8050 and RTMDISK support a blue Hot Swap LED mounted on the front panel. This LED indicates when
it is safe to remove the RTM from the front board or the hard disk from the RTM. The on-board MMC drives this
LED to indicate the hot-swap state. The following states are possible:
Table 2-7:Hot-Swap LED Description
Note:
During boot block firmware upgrade the MMC is held in reset
Note:
Depending on your BIOS configuration, a hot-swap process might turn off the front board. Please
refer to the BIOS section
“Managed FRU Deactivation Policies” of the AT8050.
LED state Description
OFF M4 state; normal state when board is in operation.
ON M1 state; ready for hot swap.
Short blink M5 state; deactivation request
Long blink M2 state; activation request.
