Replacing Components
Caution: It is important to follow these instructions when replacing
components in the MSA1000. If the procedure is done improperly, it is
possible to lose data or damage equipment. Refer to Appendix B,
“Electrostatic Discharge,” for important information on using the proper
procedures.
This section includes:
■ Replacing a Variable Speed Blower
■ Replacing a Power Supply
■ Replacing Hard Drives
■ Replacing the 2-Gb Small Form Factor Pluggable (SFP) Transceiver
Note: To take advantage of all features, check the MSA1000 website at
www.hp.com/go/msa1000 , to make sure you have the latest firmware.
Replacing a Variable Speed Blower
WARNING: The blower blades rotate at a high speed and do not stop
immediately when power is removed. Allow time for the blades to stop
rotating. Avoid touching the rotating blades when removing the blower.
Caution: Removing a power supply significantly changes the airflow within
the MSA1000. After removal of a power supply, the remaining supply starts a
timer that will shut the system down in five minutes, if the removed power
supply is not replaced.
Note: The power supply design ensures that removing a blower does not change the
airflow within the enclosure. However, do not remove a blower until the replacement
blower is available
