EVGA Z390 FTW (123-CS-E397)
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 3.1 Gen2 Header (Type-C)
The USB 3.1 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 3.1 Gen2 ports on the chassis.
These will function similarly to the USB 3.1 Gen2 Type-C port sometimes
found on a motherboard's rear I/O hub, but can also be used for the chassis'
front panel USB, auxiliary ports that mount in the card slots, and certain
devices that directly connect to the header. The USB 3.1 Gen2 Header on the
Z390 FTW is a shielded USB 3.1 Gen2 Header and supports up to 10Gb/s
with USB 3.1 Gen2.
This USB 3.1 Gen2 Header has a power limit of 3000ma (3A) @ 5V.
27. USB 3.1 Gen1 Header
The USB 3.1 Gen1 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 3.1 Gen1 ports on the chassis.
These will function similarly to the USB 3.1 Gen1 ports found on the
motherboard's rear I/O hub, but can also be used for the chassis' front panel
USB, auxiliary ports that mount in the card slots, and certain devices that
directly connect to the header.
