Chapter 2 Preparing to Install the Content Delivery Engines
Safety Warnings
Caution
If the drive PC card is exposed in the drive unit, avoid touching the PC card. If you must touch the PC
card, take ESD precautions (such as using an ESD mat and wrist strap).
Caution
If the SATA or SAS connector pins are exposed, avoid touching them. If you must touch them, take ESD
precautions (such as using an ESD mat and wrist strap).
Caution
Drive units should not be moved or transported while the power is on and the disk drive is spinning.
Caution
Drive units should normally only be installed or removed from a system with the system power off
(preferably the system should be unplugged).
Caution
“Hot plugging” a drive unit, either inserting or removing, should only be done with a fully stopped drive
(the heads are parked and the disk is stationary). Exercise extreme care during this operation to avoid
shocking the other drives in the system.
Safety Warnings
These warnings are translated into several languages in the
Regulatory Compliance and Safety

disconnect the power at the circuit breaker on DC units.
Statement 12
Warning
Before working on equipment that is connected to power lines, remove jewelry (including rings,
necklaces, and watches). Metal objects will heat up when connected to power and ground and can
cause serious burns or weld the metal object to the terminals.
Statement 43
Warning
For Nordic countries (Norway, Finland, Sweden and Denmark) this system must be installed in
a Restricted Access Location, where the voltage of the main ground connection of all equipment
is the same (equipotential earth) and the system is connected to a grounded electrical outlet.
