Onsite Policies and Procedures

Electrical safety

The static discharged by human bodies can damage static-sensitive components on the boards.
When installing and maintaining the equipment, observe appropriate electrostatic safety precautions
to prevent personnel injuries or device damage.
When operating a device in an electrostatic sensitive area, you must take electrostatic-discharge
(ESD)-preventive measures. These include wearing ESD-preventive gloves, an ESD-preventive wrist
strap, and ESD-preventive clothes to avoid personnel injury or device damage.
To prevent damage to the device, pay attention to the following during operations:
• Do not touch devices with bare hands because ESD from the human body may damage the
electrostatically sensitive elements on a board.
• When dealing with the server or any of the internal components, wear an ESD-preventive wrist
strap, ESD-preventive gloves, and ESD-preventive suit.
Hardware part replacement procedure
Removing and replacing a power canister
Before you start to replace a power canister in the NetBackup 5330 Primary Shelf or Expansion Shelf,
gather antistatic protection and a replacement power canister.
Warning: If you perform this procedure with the power turned on, you must complete it within 15
minutes to prevent the possibility of overheating the equipment. Do not remove both power canisters
from the storage shelf at the same time. One power canister must be functioning at all times.
Caution: To prevent electrostatic discharge damage, use proper antistatic protection when handling
components.
Power canister locations
The power canisters for both storage shelves are located in the rear panel of the shelf. One canister
is located at the top and at the bottom of the shelf. Each canister has two orange levers that disengage
