Hi, I've got a couple of older servers that wouldn't boot. Playing around with the power supply finds that one module in each server was bad. Which kind of defeats the purpose of redundant power supplies!<br />
<br />
This is a 3 module 650W Power Supply - Emacs R3G-6650P.<br />
<br />
The modules are GIN-6350P.<br />
<br />
With the bad one identified and removed the server boots up fine but with the bad one added to the array of three it won't turn on, it just beeps once. I've put good ones in the slot where the bad one was and it still boots with the two good ones.<br />
<br />
Is this normal behavior? I was always under the impression that if one was bad that the server would power up or keep going no matter what because its still got two good modules.<br />
<br />
Thanks!

3 Module Power Supply not Boot Because 1 Module Fail

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

Server Hardware

Hardware includes cell phones and other digital living devices, tablets, computers, servers, peripherals and components, printers and scanners, gaming consoles, networking hardware such as routers, hubs, switches and modems, storage devices and security equipment such as firewalls and other appliances.

Hardware

Components are those devices that are internal to a computer -- the PC boards, the central processor (CPU), the memory (RAM), disk and video controllers and so on.
