SW4-1, SW4-2 (Software Configuration)
These switch segments provide configuration information to the user's software. The Switch
Monitor register (Port E3h Bits 0-3) monitors the status of SW4 segments as listed below. An open
switch reads back a 0; a closed switch reads back a 1. The factory default is open for both switches.
The switch segments correspond to register bits as follows:
SW4-1 = Bit 0;
See
Section C.1.5, "Switch Monitors (E3h)" on page 80
definition.
SW4-3 (Console Redirection)
Console Redirection provides a serial communication link (through COM1) between a terminal or
terminal emulation program and the ZT 5515. This feature requires specific parameters to be set in
the BIOS Setup utility before configuring SW4-3.
SW4-3
Open (Default)
Console redirection disabled.
Closed
Console redirection enabled.
Refer to the "Console Redirection" chapter in the Intel
before attempting to use this feature.
SW4-4 (BMC Dual Domain Mode)
The BMC on ZT 5515 is able to work as a Baseboard Management Controller or Satellite
Management Controller by toggling the SW4-4. Normally, the ZT 5515 expects there to be a
Baseboard Management Controller on the IPMI bus. Flip this switch when you do not have a BMC
in the chassis.
SW4-4
Open (Default)
ZT 5515 is a Satellite Management Controller.
Closed
ZT 5515 is a Baseboard Management Controller.
SW5 (Ejector Switch)
The ejector handles are used when ZT 5515 is inserted or removed (hot swapped) from a chassis
that is powered on. When a customer wishes to remove a board from a system that is powered on
then the ejector handles should be opened just enough to disengage the handles from the chassis,
but without fully disengaging the J-connectors from the back of the chassis. This will trigger a
shutdown of the operating system and then the BMC will power off the board and light the blue hot
swap LED on the front panel. Once the blue LED on the front of the board is lit, then it is safe to
remove the board from the chassis.
