Using Videohub Routers
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:
Step 1. Ensure that the new power supply is disconnected from any electrical source.
Step 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.
Step 3. Use a number 02 size Pozidriv screwdriver to secure the power card with its two screws.
Step 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.
Step 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.
Step 6. Connect an IEC cord from the new power supply to the wall socket and turn on the power.
