IPMB-L Address
See
TABLE 5-1
for the IPMB-L addresses.
Reset_MMC#
IPMC also provides individual reset (ENABLE# pin on the AMC connector) to the
AMC slot by logically AND-ing the Reset_MMC# with the AMC PS1 input.
Reset_MMC# is driven by the H8S GPIO pins.
AMC Module Presence
The PS1# signal on the AMC connector provides presence indication. This signal is
wired to an H8 GPIO pin.
AMC Hot-Plug, Module Insertion (PCI-E)
When an AMC module is installed, the IPMC is signaled and will initially enable
management power (3.3V) to the module. The IMPC will then have the ability to
communicate with the module through the IPMI interface (IPMB_L). If the shelf
manager controller (ShMC) determines that the module is supported, it signals the
IPMC to enable payload power (12V) to the module. The IPMC controller will also
assert
HP_PRSNT#
and
HP_BUTTON# (ATTN#
) inputs to the PCI-E switch hot-plug
controller. This assertion will cause the switch to generate a hot-plug interrupt (or
Presence detect change) to the processor to indicate that the blade server is hot
inserted. This triggers a system event in the Solaris OS which causes an automatic
connect/configure operation. When this operation completes, the processor asserts
the
HW_PWR_LED#
output pin of the PCI-E switch hot-plug controller. This output is
wired to the H8 GPIO pins.
AMC Hot-Plug, Module Removal (PCI-E)
An operator can initiate module removal by opening the module handle, which
deactivates the hot-swap switch. When the hot-swap switch on the module is
deactivated, the MMC in the module sends a module hot-swap (Module Handle
Opened) event to the IPMC. If the ShMC permits blade server removal, the IPMC
asserts the
HP_BUTTON#
input pin to the PCI-E switch hot-plug controller, which
