Figure 9 ARMC/3P Reset/Power Connection Pinout
Note: On the ARMC/3P the pin for the power connector is tagged with “ATX”.
Intelligent Management Platform Bus Connector (IPMB)
The IPMB connector on an IPMI capable motherboard allows direct access to
power control functions. Connecting the IPMB connector of the ARMC/3P with
such a port using our IPMB cable makes it possible to use the IPMI over IPMB
function of the ARMC/3P. Refer to
Appendix D: Pin Assignment for the pin
assignment details of the IPMB connector.
The Set to Default (S2D) Pins
These pins may be used to reset the ARMC/3P to its factory settings. See Chapter
3: Resetting the ARMC/3P to its Factory Settings for a detailed description on
how to reset the ARMC/3P.
Serial 1, Serial 2 and PS/2
If your server does not support USB keyboard and/or mouse in all states but only
PS/2 mouse and keyboard, you need the PS/2 system cable to connect the
ARMC/3P. The proprietary PS/2 to Sub D9 cable enables the control over the host
system. The following steps describe how to use this PS/2 system cable.
1. The flat cable from the serial port (Sub D9 connector) of the High-Profile
Bracket has to be connected to the PS/2 pins on the ARMC/3P (see Figure 10).
2. Connect the PS/2 cable to the serial port (Sub D9) (see Figure 11 PS/2 System
Cable).
