CSU power distribution...

[Mjamm]

I have 12 Kentrox CSU's mounted in a 19" communications equipment rack. Each CSU has a separate 28VDC power supply. The design of the power supply is such that when plugged into an electrical outlet, it covers the next open socket as well. I am looking for a 28VDC power supply that I could use to power some or all of the CSU's from a single unit with some type of terminal bus to attach the CSU's to.

Any help help in locating such a power supply would be greatly appreciated. I know this isn't directly a Meridian question, so I appologize.

the good news is that kentrox makes a rack mount that holds a dozen kentrox csu's off a single power input.. true if you loose the ps you loose the rack.. in 20+ uears i have never lost a csu power supply.. because we are lucky, we have a glass pop so by law we don't need csu's.. except for testing and some providers who want to pretend the are god, their usless.. testing only works if you have control of both ends...

Thanks John, but I have already contacted Kentrox regarding their 12 port chassis. They told me my standalone units could not be taking out of their housings and placed in the chassis, because the backplane did not work.

I am trying to see if anyone else ran into this issue and found an alternative, such as a power distribution bus with a power supply?

haven't seen one, but i have taken the standalone units outof the housing and they worked, but no one had told me they wouldn't.. that many stand alone units do make a mess

If it is a TSERV II CSU, then it will operate anywhere between 20 to 56 vdc, so...if you have -48v laying around, you could use it instead. We use -48v for ours. I do not know why they are telling you the rack mount is incompatible unless maybe you have an older model CSU. We have done the same as John and pulled them out of the box and plugged them into the rack. Maybe it only works for us because we don't know it is not supposed to....

jpoole is right. If you take the unit out of the housing, it looks just like a blade that goes into the chasis. I too have done this.

Thanks for the feedback. One more clarification... I have the part numbers that are listed on my CSU's, can any of you confirm these are the units you dismantled and used the 77123 Tserv Card in the chassis?

TServ II - T1
77965 Complete unit
77040 Enclosure
77123 Plug-In Card

if you didn't use the unit or the enclosure, then you just used the 77123 card
