ATCA-7370/ATCA-7370-S Installation and Use (6806800P54H) 109
5.6.4 Update Channel Ethernet
The ATCA-7370 supports one Gigabit Ethernet on update channel on P20 of Zone2 connector.
It uses SerDes interface and occupies the port 0 of update channels.
5.7 Storage
ATCA-7370 supports the following types of storage:
 Front panel USB DISK (up to two ports)
 On-board solid state disk at SATA, up to 256GB (optional)
 Hot-swappable hard disks on RTM
Hard disk drive options including Enterprise class disks (various capacity options)
5.8 IPMC
The blade features an Intelligent Platform Management Controller (IPMC) compliant to PICMG
3.0 and IPMI 1.5 and 2.0 (SOL only). The IPMC is a management subsystem providing
monitoring, event logging, and recovery control. The IPMC serves as the gateway for
management applications to access the payload hardware.
The IPMC firmware (FW) is stored in two independent memory images. Crisis recovery control
is provided to allow reboot of the IPMC from a second image if the upgraded FW image is
corrupted. FW images can be upgraded via HPM.1/IPMI using either IPMB or KCS interface.
The IPMC supports the initiation of a graceful shutdown of the host CPU. The IPMC can force
the CPU to reset. It also controls the power and reset of the payload.
The IPMC provides a watchdog that supervises the payload. If enabled, the payload software
needs to retrigger the watchdog to prevent time-out. A watchdog time-out can generate a
NMI, a payload reset or disabling/cycling of the payload power. The watchdog settings, which
includes enable/disable, is changed by payload software (setup menu). Time-out values must
be selected from as short as seconds to as long as minutes.
A separate hardware watchdog which cannot be disabled, supervises the IPMC. IPMC FW
retriggers the watchdog timer.
