Inserting the Server Into a Rack
To insert the server into a rack, follow these steps:
WARNING! Do not attempt to lift the server alone. The server can weight as much as 22.7
kilograms (50 lbs). Serious injury can result if this warning is not observed.
1. Engage the sever slides or mounting kit.
2. Slide the server inward and push the server into the rack until it is in position.
3. Connect the server cables to the rear-panel connectors.
4. Connect the rack or facility ground cable to the chassis ground lug (Figure 6-1).
5. Replace or tighten the screws that fasten the server to the rack.
Component Classification
The server components are classified into three major categories: hot-swappable, hot-pluggable,
and cold-swappable. A brief explanation of each category and the server component classification
follow.
Hot-Swappable Components
A component is hot-swappable if you can remove it from the chassis while the server is running.
Hot-swappable components require no software intervention prior to removing the component.
NOTE: Hot-swappable components are signified with red touch points.
The following are hot-swappable components:
• Chassis fan units
• Power supplies
Hot-Pluggable Components
A component is defined as hot-pluggable if you can remove it from the chassis while the server
is running. Software intervention is required prior to removing a hot-pluggable component.
NOTE: Hot-pluggable components are signified with red touch points.
The following are hot-pluggable components:
• Disk drives
• PCI-X cards
Cold-Swappable Components
To remove and replace cold-swappable components, or components that are neither hot-swappable
nor hot-pluggable, you must shut down the operating system and power off the server. For
complete instructions on shutting down the operating system and powering off the server, see
operating system documentation.
NOTE: Cold-swappable components are signified with blue touch points.
The following are cold-swappable components:
• Front grill
• Top cover
