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 replacement procedure
This document describes how to remove and replace damaged or faulty NetBackup 5330 storage
shelf SAS data cables while the appliance is operating. Because of SAS cabling redundancy, you
can replace the damaged or faulty SAS data cables without shutting down the entire NetBackup 5330
Appliance system.
Removing and replacing NetBackup 5330 storage shelf SAS data cables
Review the following:
• This procedure pertains to NetBackup 5330 Appliance installations that use multiple Expansion
Storage Shelfs.
Note: This procedure does not apply to NetBackup 5330 Appliance systems that do not use any
Expansion Storage Shelfs.
• Remove only one SAS cable at a time.
SAS cable redundancy is designed into the NetBackup 5330 Appliance system. As a result, you
can remove and replace one SAS cable at a time without turning off the system.
