Hub Board
The Hub board distributes the signals, data and power to other hardware components in the
cabinet, such as Receiving card, power supply and Pixel cards. Each Hub board has a Power
supply unit (PSU) and a Receiving card.
Hub Board Interfaces
The Hub board has several interfaces to distribute power and data. The Hub Board front
(Figure 25) has the following interfaces:
8 Pixel card network interfaces (A): For data transmission and power supply to Pixel cards.
2× 2Ethernet ports (B): For data transmission from Hub board to Hub board. (Only the left
Ethernet port transmits data. The right Ethernet port has no function.)
16 screw connections to cabinet (C): To secure the Hub board in the cabinet.

The backside of the Hub board has several interfaces for data and power distribution (Figure
26):
4 pin connectors to Power supply unit (D): Distribute the power from PSU to the Hub
board, e.g. for the Pixel cards or Receiving card.
1 Power-good-connector (E): Sends status of power supply to monitoring software.
Be careful when re-assembling the module, the connectors bend easily.
1 Receiving card (F): Receives data and signal input via the Ethernet cable from the
external controller. They process the signals and forward them to the Pixel cards.
1 Signal light cable (G): Forwards the status input of the module to the Signal lights on the
back of the module.
