LEDs
Module Management
LEDs
• LED1 (red): Out-of-Service LED
• LED2 (red/green/amber): Health LED
• HS LED (blue): The hot swap indicator provides basic feed-
back to the user on the hot swap state of the
module. The HS LED states are off, short
blink, long blink, and on.
User-Specific LEDs
• ULED3 (red/green): AMC Ethernet port A link signal status or
POST code LED
• ULED2 (red/green): AMC Ethernet port B link signal status or
POST code LED
• ULED1 (red/green): Freely configurable or POST code LED
• ULED0 (red/green): Freely configurable or POST code LED
Timer
Watchdog Timer • Software-configurable, two-stage Watchdog with programmable timeout
ranging from 125 ms to 256 s in 12 steps
• Serves for generating IRQ, hardware reset or both in cascaded mode
System Timer
• Two groups of four global 32-bit timers clocked with MPX clock or RTC
clock input
• Timers within each group can be joined to time longer durations
• Hardware delay timer for short reliable delay times
IPMI
Module Management
Controller
• Renesas H8 microcontroller with 40 kB RAM and redundant 512 kB
MMC Firmware Flash with automatic roll-back strategy
• The MMC carries out IPMI commands such as monitoring several on-
board temperature conditions, board voltages and the power supply sta-
tus, and managing hot swap operations.
• The MMC is accessible via a local IPMB (IPMB-L) and Keyboard Style
Interfaces (KCS).
Hot Swap The AM4101 has full hot swap capability.
Thermal Management CPU and board overtemperature protection is provided by:
• Four temperature sensors for monitoring the board temperature
• CPU internal sensors
• Specially designed heat sinks
