HP BladeSystem c7000 Carrier-Grade Enclosure Maintenance and Service Guide

Warning and caution messages
WARNING! To reduce the risk of personal injury or damage to equipment, heed all warnings
and cautions throughout the installation instructions.
WARNING! To reduce the risk of personal injury or damage to the equipment, you must
adequately support enclosures during installation and removal.
WARNING! Before installing an enclosure in the rack, be sure that all hot-plug power supplies,
server blades, and interconnects are removed from the enclosure. Blanks can be left in the enclosure.
WARNING! To reduce the risk of electric shock or damage to the equipment:
• Do not disable the grounding cables. The grounding cables are an important safety feature.
• Ensure that all enclosures and modules in the rack are grounded to the rack, and that the rack
is connected to a common bonding network.
• Do not route the power cord where it can be walked on or pinched by items placed against
it. Pay particular attention to the plug, electrical outlet, and the point where the cord extends
from the server.
WARNING! To prevent damage to server components, do not mix AC and DC power supplies
in the same enclosure.
WARNING! To reduce the risk of electric shock or damage to the equipment, enter enclosures
or perform service on system components only as instructed in the user documentation.
WARNING! A risk of electric shock from high leakage current exists. Before connecting the DC
supply to power enclosures, be sure that the electrical outlets are properly grounded (earthed).
WARNING! Protect the equipment from power fluctuations and temporary interruptions with a
regulating facility UPS device. This device protects the hardware from damage caused by power
surges and voltage spikes and keeps the system in operation during a power failure.
Rack doors
To provide access to all sides of the rack while you are installing the various components, first
remove the rack doors. If your rack has side panels, also remove them before installing mounting
brackets and other hardware.
To remove the component:
1. Unlock the door with the key.
2. Open the latch.
3. Open the door.
4. Remove the ground strap.
