Piggy Backing UPS Units

[Anonymous user]

I'm sure this has come up many times before. Searches have turned up answers directing to a kbase article that I have not been able to access for several days now. This is one of the answers I have turned up. http://forums.apc.com/message/22738#22738 That kbase link is dead so I am asking again. I have inherited a new client that appears to have quality gear, but has been deployed in an improper fashion. The basic scenario is that they have an APC-2200XL UPS that has every port full of equipment. Upon closer examination I have found that a CEN-UPS1250 with a high wattage commercial AV power amplifier is plugged into the APC-2200XL UPS. There is also a smaller UPS and two PDU units plugged into the APC-2200XL UPS. All outlets on all UPS systems and PDUs are all full. Is this CEN-UPS1250 (with amp) and other UPS device plugged into the APC-2200XL UPS a big no-no? I have already ordered an APC SMX2200RMLV2U X, and an electrician to convert two unused dedicated 30 amp circuits to permit plugging the CEN-UPS1250 and other UPS into direct AC power. I just want to justify my actions. Equipment is getting damaged when there are power anomalies and nearby lighting strikes. Thank you.

Here is the updated link for what you found. We switched our knowledge base system over last year and that is one of the old links.
