Removal and replacement procedures Required tools You need the following items for some procedures: • DIMM tool (provided on the DIMM baffle) • T-15 Torx screwdriver (provided on the DIMM baffle) • T-10 Torx screwdriver (not provided with the server blade) • HP Insight Diagnostics software ("HP Insight Diagnostics" on page 64) Safety considerations Before performing service procedures, review all the safety information. Preventing electrostatic discharge To prevent damaging the system, be aware of the precautions you need to follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device. To prevent electrostatic damage: • Avoid hand contact by transporting and storing products in static-safe containers. • Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations. • Place parts on a grounded surface before removing them from their containers. • Avoid touching pins, leads, or circuitry. • Always be properly grounded when touching a static-sensitive component or assembly. Server blade warnings and cautions WARNING: To reduce the risk of shock or injury from high-current electrical energy, do not remove the server blade access panel and then install the server blade into the enclosure. WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the internal system components to cool before touching them. CAUTION: Do not operate the server blade with the access panel removed. Operating the server blade in this manner results in improper airflow and improper cooling that can lead to thermal damage.

Required tools
You need the following items for some procedures:
•
DIMM tool (provided on the DIMM baffle)
•
T-15 Torx screwdriver (provided on the DIMM baffle)
•
T-10 Torx screwdriver (not provided with the server blade)

Safety considerations
Before performing service procedures, review all the safety information.
Preventing electrostatic discharge
To prevent damaging the system, be aware of the precautions you need to follow when setting up the system
or handling parts. A discharge of static electricity from a finger or other conductor may damage system
boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device.
To prevent electrostatic damage:
•
Avoid hand contact by transporting and storing products in static-safe containers.
•
Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
•
Place parts on a grounded surface before removing them from their containers.
•
Avoid touching pins, leads, or circuitry.
•
Always be properly grounded when touching a static-sensitive component or assembly.
Server blade warnings and cautions
WARNING:
To reduce the risk of shock or injury from high-current electrical energy, do not
remove the server blade access panel and then install the server blade into the enclosure.
WARNING:
To reduce the risk of personal injury from hot surfaces, allow the drives and the
internal system components to cool before touching them.
CAUTION:
Do not operate the server blade with the access panel removed. Operating the server
blade in this manner results in improper airflow and improper cooling that can lead to thermal
damage.
