How To Add A Redundant Power Supply To Blade 4

How To Add A Redundant Power Supply To Blade 4

The kit will come with the following:
QTY: 1) SPS-3016 power supply
QTY: 1) IEC power filter to Molex plug assembly
QTY: 1) 5-pin JST to 5-pin JST cable assembly
QTY: 1) Plastic insulator
QTY: 1) Small zip tie
QTY: 1) Patch clip
QTY: 4) 4-40 1/4 Phillips screws

Before we get started with this procedure, the Blade should be powered down, not rack mounted and already have the cover of the Blade removed.

The rear of your Blade will have a pre-cut spot for the second IEC power filter as seen at left. To remove this piece simply push in with a tool at the top or bottom to break it free, then rotate it back and forth until you can remove it from the chassis.

Next you want to insert the IEC filter assembly in the chassis by feeding the Molex plug attached through the hole from the outside first, making sure to orient the IEC plug the same way as the existing one. (Once the IEC is seated in the chassis it is very difficult to remove it again.) Then just snap the IEC plug into place in the chassis.

Place the plastic insulator in the front corner of the Blade, next to the existing power supply. Take note of the four standoff locations and the holes in the insulator. The plastic insulator will fit down nicely once the holes are lined up with the standoffs.



Install the SPS-3016 power supply onto the standoffs you just placed the plastic insulator around, using the four (4) Phillips head 4-40 screws supplied with this kit. Ensure the screws are tight without over torquing them.

Plug the Molex connector from the IEC power filter assembly into the SPS-3016 power supply utilizing the connector labeled CT1 on the power supply. Ensure the Molex connector is fully seated and the latch on the side has fully engaged with the connector mounted on the power supply.

Run the JST power cable between the connector labeled CT2 on the SPS-3016 and the main CPU card of the Blade. The connector on the Blade will be one of the following depending on the CPU card version:

Notes
If you have a CPUCM4 card it will be the connector labeled CT14.
If you have a CPU-E4 card it will be the connector labeled CT12.

The JST connector on the CPU card is in the same location no matter which board type your Blade has installed in it. Please refer to the picture below to help identify the location.



Use the small zip tie about half way on the JST wire harness to secure the wires together and to help keep them from getting caught under the cover when it is reinstalled. Place the patch clip about half way on the wires going between the IEC power filter and the Molex connector plugged into the power supply.

Then remove the protective film over the double sticky tape on the bottom of the patch clip on secure it to the CPU card as seen above.
