HP Integrity rx2660 Server User Service Guide

Server Component Classification
The server components are classified into three major categories:
• Hot-swappable
• Hot-pluggable
• Cold-swappable
The following sections provide a brief explanation of each category and the classifications for the
server components.
Hot-Swappable Components
A component is defined as hot-swappable if you can remove it from the server while the server
remains operational, and requires no software intervention prior to removing the component.
NOTE: Hot-swappable components are signified with red touch points.
The following are hot-swappable components:
• Fan unit
• Power supply (power supplies are only hot-swappable one at a time)
• Disk drive filler
Hot-Pluggable Components
A component is defined as hot-pluggable if you can remove it from the server while the server
remains operational, but software intervention is required prior to removing the component.
NOTE: Hot-pluggable components are signified with red touch points.
The only hot-pluggable components are the hard disk drives:
Cold-Swappable Components
To remove and replace cold-swappable components (components that are neither hot-swappable
nor hot-pluggable), 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 Chapter 4
(page 85).
NOTE: Cold-swappable components are signified with blue touch points.
The following are cold-swappable components:
• Front bezel
• DVD drive
• DIMMs
• Single- or dual-core processors
• System battery
• iLO/MP battery
• SAS core I/O card
• PCIe expansion card (optional)
• Smart Array P400 controller (optional)
• I/O backplane assembly
• Power backplane
