Blade Power enclosure

[Wayne Blackwell]

Can anyone tell me if the if the BL rack mounted 3U power enclosure provides any mains filtering we have had several mains spikes over the past few months leading to two unexplainable Blade unit failures TIA

what you use three faze or one faze, 110v ? or 220v ? also how many server you pull out from one enclosure

Single Phase 220V

4 power supplies in the power enclosure supplying one Blade enclosure with two switches and 7 x BL20p G2 Blades

Thanks for your reply but does anyone know if these power supply units filter spikes as stanard? I seem to remember reading that they do but can't find the relavent document

Again TIA
