Switch number
Description
Definition
SW5-1 Password override The default position is Off. Changing this switch to the On
position overrides the power-on password.
SW5-2 Trusted Platform Module (TPM)
physical presence
The default position is Off. Changing this switch to the On
position indicates a physical presence to the TPM.
SW5-3 CMOS memory The default position is Off. Changing this switch to the On
position indicates to clear CMOS memory.
After clearing the CMOS memory, change the switch back to
Off position to turn on the compute node (see
“Power on the
compute node” on page 65
for instructions).
SW5-4 Reserved The default position is Off.
KVM cable
Use this information for details about the KVM cable.
Use the KVM cable to connect external I/O devices to the compute node. The KVM cable connects through
the KVM connector (see
“Compute node controls, connectors, and LEDs” on page 15). The KVM cable has
connectors for a display device (video), two USB 2.0 connectors for a USB keyboard and mouse, and a serial
interface connector.
The following illustration identifies the connectors and components on the KVM cable.
