Timing Input

The timing input LED is mainly used to quickly visualize the status of the external
reference timing source (see
detection of PPS/10MHz inputs on the front-panel. Blinking behavior in this con-

SFP Ports

The network ports of the device are arranged in a dual stack SFP cage. The fol-
lowing table represents only the two first ports but can be extrapolated to the

as it does not differentiate TX/RX but utilizes the arrows to indicate the upper-
/lower port and their corresponding states:
