Denver International Airport I just wanted to repeat to you how grateful we are at DIA for the outstanding support and service you recently provided us when you masterfully oversaw our purchase and installation of one of your APC UPS units (40 kW) in our IT Server Room here at the Airport. As you know the IT server room is a critical area at Denver International Airport. We heavily depend on its services and need its servers to be backed up with a dependable UPS unit. Although this installation was particularly problematic, you and your team helped us overcome a number of obstacles and saw us through to the end. Not only are my colleagues here at DIA Technical Maintenance grateful for your very careful attention to detail and scrupulous support but the staff at IT are also very pleased with the outcome. Thanks again. Robert Randall, P.E., MBA Senior Engineer Denver International Airport | Citadel Security Software The short answer to your questions is that yes, we did purchase several UPS's and PDU's from LED. This includes small rack mount units up to approximately 30 APC Netshelter cabinets complete with 30 managed/metered 3-phase PDU's, 12 environmental monitors, 8 KB/monitor units and 22 specialized PDU's for our IBM Blade Centers. We also bought two 40-80kVA Symmetra 3P UPS units. All of it is controlled by APC's infrastructure management monitoring system and software.
ALL of it has worked flawlessly, except for one battery (out of 64), which LED had replaced the next business day.
As far as LED is concerned, you should know that I have been an IT professional for over 30 years. I have designed and installed about a dozen class A computer rooms. Without a doubt, LED is the best power systems vendor I have ever used.
On a personal note, I have worked very closely with Dennis Procailo and Greg Santschi. I have found them both to have the high level of integrity, knowledge and professionalism that we require from our vendor prtners. During the design phase they identified several key power issues we would have missed. Installation was fast and efficient and we have been operating smoothly since last November's install.
As you might have guessed, I will be happy to provide LED a stellar reference. Scott Millis Director, Technology Support Citadel Security Software |
