card and other technical information are:
Description
The MegaRAC™ Express card has an Intel 80L960JA 3.3V
embedded 32-bit processor running at 16 MHz. This processor
includes 2 KB of instruction cache and 1 KB of data cache with
write-through operation. The MegaRAC™ Express card has an
AMI MG9063 ASIC that interfaces between the host PCI bus and
the local i960JA processor.
MegaRAC™ Express includes 2 MB flash ROM that contains the
firmware image and DRAM for operational memory. The
MegaRAC™ Express card includes 16MB DRAM cache memory.
The firmware will operate from this memory. The firmware will
maintain adequate stack and heap for all internal processing. A
128 KB NVRAM area provides storage for configuration
information, event logs, and captured text screens.
Out-of-band access is established through a path other than the
system's LAN or WAN connection, such as a telephone line or the
onboard network line. It uses the onboard 10 Mbps LAN, or
onboard serial port, or an external serial Modem.
Monitors hardware health parameters (voltages, temperatures, fan
status, and chassis intrusion.)
Used to initiate an immediate server boot. The MegaRAC™
Express card can detect when the server has lost power or has
been reset by using a watchdog timer.
The BIOS on the server motherboards allows you to capture video
text sequences the firmware stores in NVRAM. The boot
sequences and I/O Port 0080h outputs are captured and stored in
NVRAM.
