EVGA Z490 FTW (122-CL-E497)
22. Front Panel Audio Connector
This motherboard header is used to plug in the audio cable included with most
PC chassis. This connector is required for audio recording and/or playback
via the audio connectors on the chassis. This header has a connector that
looks similar to the USB2.0 header and uses the standard "HD Audio" jack.
Some chassis may provide two headers: one labeled HD Audio, and one
labeled AC'97 – an AC'97 cable is not compatible with this header on the
Z490 FTW.
23. PC Speaker
This is a small mono low-fidelity speaker, which is permanently attached to the
motherboard. Its primary use is for debugging purposes. A POST beep may
indicate a successful POST or various tones for USB initialization, while other
beeps may indicate an issue during the POST process. Please see Page 153 for
more details.
24. Front Panel Connectors
The Front Panel Connectors are the four main chassis connections. These
include the Power Switch, Power LED, Reset Switch, and HDD LED. The
Power and Reset switches are "Momentary Switches," rather than "Latching
Switches," which means the connection between two posts only needs a brief
moment to turn on the device, as opposed to requiring a constant connection.
For example, the Power and Reset switches can be triggered instantly with a
screwdriver by simultaneously touching the + and - posts.
The Power LED will power on with the system, indicating the system is on and
can blink in conjunction with CPU activity.
HDD LED will blink during access to the SATA ports; this is not activated for
M.2 SSDs.
25. CMOS Battery
The CMOS battery backup provides uninterruptable power to the BIOS/UEFI
to store all its settings; otherwise, each power on would act as if the BIOS was
just reset. These batteries typically last several years and rarely need to be
replaced.
26. USB 3.2 Gen2 Header (Type-C)
The USB 3.2 Gen2 header is used to connect additional USB interface plugs to
the motherboard; these headers are most often used to connect the
motherboard to the chassis to enable the USB 3.2 Gen2 ports on the chassis.
These will function similarly to the USB 3.2 Gen2 Type-C port sometimes
