General status LEDs (F):
These LEDs indicate the operating status of the ML-N4000.
LED
Meaning
Connect
Connection between ML-N4000 and XORAYASuite is established
Logging
Logging in progress
LED flashes as the logging stops, because the stopping process
may take longer depending on the queue fill level
int. SSD
Flashes when accessing the internal storage medium
ext. SSD
Lights up when cable connection to XORAYA ESU is established
▪ Red: connection enabled (locked)
▪ Green: connection disabled via button (unlocked)
Info
ML-N4000 is DHCP server
Service
Lights up constantly when the ML-N4000 is in firmware update or
recovery mode
Displays different error codes by flashing
USB H.

USB D.
(Currently not used)

10 Gbit Ethernet interface (G):
This interface can be used for data recording or as a faster alternative to the
1 Gbit host interfaces (H). A plugged-in SFP+ module is required. X2E
recommends the module FTLX8573D3BTL from Finisar.
LAN host interfaces (H):
The ML-N4000 features four ports to connect to a switch or directly to a PC.
This is necessary to control the ML-N4000 via software and exchange data.
ESU interface (I):
This port is used to connect the additional device XORAYA External Storage
Unit (ESU). If the ML-N4000 detects this device, the measurements in HDD
mode are saved there instead of to the internal storage medium.
(➔ HDD mode)
The LEDs in the following table are both on the front and on the back side of
the XORAYA ESU.
