Building a Universal Videohub 72
Universal Videohubs contain electrostatic sensitive devices. It is essential to discharge yourself of static
electricity before handling any of these devices, just as you would when installing devices in to a computer.
We recommend the use of an antistatic wrist strap when handling any of these devices.
Universal Videohub 72
Universal Videohub 72 ships as an empty rack frame except for a fan tray containing three hot-swappable
fans. 9 rack units of space should be reserved for the installation of the Universal Videohub 72. 2 RU of this
reserved space should be left above Universal Videohub 72 for heat dissipation unless mounted at the
top of an open rack where there is no obstruction to airflow above the Videohub. Only 7 RU is required if
Universal Videohub 72 is mounted at the top of an open rack. The space reserved for Universal Videohub
72 includes 2 RU of clearance under the base of the Videohub to allow the fan tray to be removed and the
fans replaced. Please refer to the Troubleshooting section of this manual for instructions on "Replacing a
fan in Universal Videohub".
Universal Videohub 72 customers will need to purchase and install a single Universal Videohub 450W
Power Card and external "brick" power supplies. Up to three brick power supplies can be connected to the
power card.
Universal Videohub 72 should be securely mounted in a rack before populating it with any additional
hardware as it will quickly become heavy.
It is essential that unpopulated card slots be covered with the blanking plates which are supplied with the
Universal Videohub. Failure to cover all slots may lead to Universal Videohub overheating.
Universal Videohub 72 Crosspoint
Once the Universal Videohub 72 has been mounted in a rack, it needs to be fitted with a crosspoint card.
The crosspoint card is the "brains" of any Universal Videohub and performs video route switching.
To install the Universal Videohub 72 Crosspoint card, hold the card in a vertical orientation by its two levers.
The BNC, Ethernet and other ports should be towards the bottom end of the card. Gently insert the unit
into its slot and ensure the top and bottom edges of the card follow the black guides. Now firmly push both
levers flat to fully engage the multi-pin connectors with the motherboard. Mating pins ensure that the card
precisely engages with the motherboard without damaging the multi-pin connectors. Use a number 01 size
Pozidriv screwdriver to secure the screws on the two levers of the crosspoint card.
Should you ever need to remove a Universal Videohub 72 Crosspoint card, remove the two screws and then
pull open the two levers. Once the levers have been fully opened, gently extract the card along its guides.
