Working inside a Netfinity 5600 server with power on The Netfinity 5600 server is designed with special features that make it highly available. These features include hot-plug PCI expansion slots and hot-swap fans. You can add or replace PCI adapters (if supported by the operating system) or replace a fan which no longer functions. In the past you would need to power off the server and disconnect power to perform these operations. With the hot-plug features you remove the cover of the server with the power on - something most people have not done before. The Netfinity 5600 server is designed to operate safely while powered on with the cover removed. The server is designed to protect you and the server. Here are some simple guidelines to follow when you work inside a Netfinity 5600 server that is powered on: Avoid loose-fitting clothing on your forearms. Button long-sleeved shirts before working inside the server; do not wear cufflinks while you are working inside the server. Do not allow your necktie to hang inside the server. Remove jewelry, such as bracelets and loose-fitting wrist watches. Remove items from your shirt pocket (such as pens or pencils) that could fall into the server as you lean over it. Take care to avoid dropping any metallic objects, such as paper clips, hair pins, or screws, into the server. Netfinity 5600 - Type 8664 99
