Planning Your Videohub Installation

Power Supply Options
External power supplies connect to Universal Videohub 72 via a single power card. The Universal Videohub
450W Power Card provides connections for up to three 150W brick-style power supplies, which must be
purchased separately.
A Universal Videohub 72, which is fully populated and running at maximum power consumption, can be
powered by two 150W "brick" power supplies. A third power supply can be connected to ensure continued
operation should one power supply fail. The 150W power supplies are universal (international) power
supplies for use in all countries and feature thumb screw fasteners. You will need to provide a standard IEC
cord, with a C13 connector, for each power supply. When fully populated with three power supplies, three
mains power sockets will be required.
If you have only partially populated your Universal Videohub 72 with cards, you might be able to power
it with one 150W power supply and preferably use a second power supply for failover redundancy. If you
choose this option, temporarily disconnect the second power supply and then check the Power Overload
light on the crosspoint card after installing any cards. If the Power Overload light illuminates, you will have
to add a 150W brick power supply or remove some cards to ensure that all cards are receiving power. Don't
forget to reconnect the second power supply when you have finished checking the Power Overload light.
For peace of mind, we recommend connecting and powering the three power supplies at all times to
ensure sufficient power, and power redundancy, with all card combinations.
Universal Videohub 72 has a single slot for a power card. Accordingly the high power supply recommended
for Universal Videohub 288 is ill-suited to Universal Videohub 72 as it does not provide power redundancy
to Universal Videohub 72, is more expensive and requires an additional 1 RU of space below Universal
Videohub 72.
