SGPIO Headers
There are two Serial Link General Purpose Input/Output (I-SGPIO1, I-SGPIO2) headers
located on the motherboard. The SGPIO headers are used to communicate with the enclosure
management chip on the back panel.
I-SGPIO 1/2
I-SGPIO1 I-SATA 3.0 Ports 0-3
I-SGPIO2 I-SATA 3.0 Ports 4-5
Onboard Buzzer
The Onboard Buzzer (SP1) is used to provide audible indicators for various beep codes. See
also Speaker Header, JD1.
Speaker Header
JD1 is used to connect an extra speaker. By default, pins 3-4 are closed with a cap to enable
the onboard buzzer at SP1. To use an extra speaker instead, connect the speaker connector
to pins 1-4.
Disk-On-Module Power Connector
Two power connectors for SATA DOM (Disk-On-Module) devices are located at JSD1 and
JSD2. Connect appropriate cables here to provide power support for your Serial Link DOM
devices.
