CHAPTER 4: INTERFACES
G500 SUBSTATION GATEWAY INSTRUCTION MANUAL GE INFORMATION 39
External Interfaces
These interfaces are directly accessible from front or rear of the Unit.
USB Slave
The front of the unit includes a USB B port. The G500 behaves as a USB Serial device on this
port. This is to connect a debug device, for example a service personnel laptop. If enabled
this port can show boot and OS output to Serial console. Configure the Host device to the
same parameters as the G500.
The USB serial port can, when enabled in UEFI-Setup, redirect the UEFI-Setup screen. This is
useful in cases where no display is available or the Display Port is disabled.
The USB serial port default settings are 115 kBaud, 8 data bits, no parity and 1 stop bit
(abbreviated as 1
15000 8N1).
Ethernet Port
The front of the unit includes a single RJ45 Ethernet connector, used to connect the
management network. If enabled the DASH functionality is available via this connection.
DASH: • SOL port
• Remote USB
• Remote power control
• Remote board info
The port uses an RTL8111EP network. Drivers are freely available for several operating
systems on the Realtek website.
