Installing a second Power Supply while Universal Videohub 288 is running
If you wish to install a redundant or replacement power supply while Universal Videohub 288 is
already running from a power supply, please carry out the installation procedure in the
following order:
1 Ensure that the new power supply is disconnected from any electrical source.
2 Orient the new power card so that the MAIN POWER label appears at the top
of the card. Now insert the power card into the spare power card slot.
3 Use a number 02 size Pozidriv screwdriver to secure the power card with its two screws.
4 If you are installing a redundant power supply for the first time, install the 1 RU chassis
below the first power supply, leaving 1 RU of clearance between the two power
supplies for heat dissipation. If you are installing a replacement power supply, install the
replacement 1 RU chassis where the faulty unit was previously located.
5 Connect the new power cable between the connectors on the new power card and the
new power supply. Tighten the thumb screws on both power connectors.
6 Connect an IEC cord from the new power supply to the wall socket and turn on
the power.
