Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD occurs when
electronic components are improperly handled; it can result in complete or intermittent failures.
Always follow ESD-prevention procedures when removing and replacing components.
• Ensure that the chassis is electrically connected to earth ground.
• Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact.
• Connect the clip to the ESD-strap connection jack (to the left of the power switch on the rear of the
chassis) or to an unpainted chassis frame surface.
For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10
megohm (Mohm).
Caution
Unpacking and Inspection
Do not unpack the Cisco VG450 until you are ready to install it. If the installation site is not ready, keep the
chassis in its shipping container to prevent accidental damage.
The Cisco VG450, cables, printed publications, and any optional equipment you ordered might be shipped in
more than one container. When you unpack each shipping container, check the packing list to ensure that you
received all the following items:
• Cisco VG450 Voice Gateway
• Power cord, 6-foot (1.8-meter)
• RJ-45-to-DB-25 adapter cable (labeled Console)
• RJ-45-to-DB-9 adapter cable (labeled Auxiliary)
• Rack-mounting brackets for 19-inch rack (one pair) with screws for attaching to chassis
• Chassis guard for wall-mounting applications
• Grounding lug and fasteners
Inspect all items for shipping damage. If anything appears damaged, or if you encounter problems when
installing or configuring your system, contact a customer service representative.
Install the Cisco VG450 Voice Gateway
To prevent damage to the chassis, never attempt to lift or tilt the chassis by holding it by the plastic panel on
the front. Always hold the chassis by the sides of the metal body.
