Server Component Classification; Hot-Swappable Components; Hot-Pluggable Components - HP Integrity rx2660 User's & Service Manual

Follow the safety conventions listed below to ensure safe handling of components, prevent injury,
and prevent damage to the server:
• When removing or installing servers components, follow the instructions provided in this
guide.
• If installing a hot-swappable or hot-pluggable component when power is applied (fans are
running), replace the server cover immediately to prevent overheating.
• If installing a hot-pluggable component, complete the required software intervention prior
to removing the component.
• If installing an assembly that is neither hot-swappable, nor hot-pluggable, disconnect the
power cable from the external server power receptacle.
WARNING!
from the server prior to removing or installing server hardware (unless you are removing
or installing a hot-swappable or hot-pluggable component).
Voltages are present at various locations in the server whenever an ac power source is
connected. This voltage is present even when the main power switch is turned off.
Failure to observe this warning may result in personal injury or damage to equipment.
• Do not wear loose clothing that may snag or catch on the server or on other hardware
compoonents.
• Do not wear clothing subject to the buildup of static electricity, such as wool or synthetic
materials.
• If installing an internal assembly, wear an antistatic wrist strap and use a grounding mat,
such as those included in the Electrically Conductive Field Service Grounding Kit (HP
9300-1155).
• Handle accessory boards and components by the edges only. Do not touch any metal-edge
connectors or any electrical components on the accessory boards.

Server Component Classification

The server components are classified into three major categories:
• Hot-swappable
• Hot-pluggable
• Cold-swappable
A brief explanation of each category and the classifications for the server components follow.

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.
Ensure that the system is powered off and all power sources are disconnected
