Usb Type-C Console Port; Fans - NETGEAR GSM4248PX Hardware Installation Manual

switch to a DB9 port on a VT100-compatible terminal or a Windows-based computer
that runs VT100 terminal emulation software.

USB Type-C console port

The switch provides one USB Type-C console port for console access only. The product
package includes one USB console cable with a USB-A connector and a USB-C connector.
You can use this cable to connect the USB Type-C console port on the switch to a USB
port on a VT100-compatible terminal or a Windows-based computer that runs VT100
terminal emulation software.
Note: For you to be able to use the USB Type-C port and access the switch from a
Windows-based computer that runs VT100 terminal emulation software, you must install
the USB driver on the computer. To download the VT100 terminal emulation software
and Windows USB driver, visit netgear.com/support.

Fans

The switch includes internal fans that support intelligent operation, which enables the
switch to automatically start the operation of the fans, gradually increase the speed of
the fans, and either halt PoE or block traffic if the temperature exceeds a critical level.
The fans support the following modes:
• Off : The fans are off and produce no noise. This mode is not supported on all
models. For models that support this mode, you can only manually set the fans in
Off mode (see below).
• Quiet: The fans function with variable speeds, depending on the temperature, traffic
load, and use of the PoE budget. The fan speed can temporarily reach 100 percent.
Quiet mode is the default mode. At 25 or 30 percent speed, the fans produce minimal
noise. Fan noise increases at 50 percent speed and even more so at 75 percent
speed. At 100 percent speed, the fans produce considerable noise.
• Cool: The fans consistently function at 100 percent speed, provide maximum cooling,
and produce considerable noise.
In Quiet mode, the switch might automatically change back and forth between Cool
mode and Quiet mode until a temperature, PoE budget, or traffic load condition
returns within thresholds.
You can manually control the fans through either the audio-video (AV) local browser
user interface (UI) or the command-line interface (CLI). For more information about
