Environmental, Safety, and Regulatory Certifications

For information regarding safety and regulatory certifications applicable to the Acme Packet 4900, refer to the Acme Packet Platforms Safety and Compliance Guide.

General Safety Precautions

To ensure general safety, follow the safety precautions listed in this section.

Fan Module

To avoid overheating the system, do not block the air inlets or the fan module, or otherwise obstruct airflow to the system. Keep the area around the Acme Packet 4900 System clean and clutter-free.

Unit Maintenance

Aside from the fan module, power supply, air filter, transcode module, TDM module and mainboard, there are no user-serviceable parts inside the Acme Packet 4900 chassis. Only professionals trained to maintain, adjust, or repair the Acme Packet 4900 System may provide these services.

Fiber Optic Cable

Looking into a fiber optic cable can cause eye damage. Never look directly into the end of the fiber optic cables. Instead, use a fiber optic power meter to determine if power is present.

Environmental Specifications

Adhere to the stated environmental specifications for the Acme Packet 4900.

Using This Guide

Read and understand all notes of warning and caution included in the Acme Packet 4900 System documentation. These warnings and cautions are designed to keep you safe and protect the Acme Packet 4900 System from damage.

Precautions

To protect yourself from harm and the Acme Packet 4900 System from damage, follow these electrical safety precautions:

Precautions

  • Note the location of the emergency power circuit breaker for the power to the equipment rack and the room where the Acme Packet 4900 is located.
  • If your unit or system has a System Power switch, note its location.
  • If an electrical accident occurs, remove power from the system immediately by unplugging the chassis.
  • Always disconnect the power from the system when removing an Acme Packet 4900 from its rack.
  • When disconnecting power:
    • Disconnect the circuit breaker at the rack.
    • Unplug or unscrew the power cords from the power supplies.
  • Use grounded AC power cords that are plugged into grounded electrical outlets.
  • Never use extension cords to power the Acme Packet 4900.
  • Ensure that the installation facilities have proper grounding systems and include a grounded rack structure or local grounding bus bar.
  • When installing the Acme Packet 4900 in an equipment rack, always make the ground connection first and disconnect it last when removing it.
  • Use shielded Category 5e or 6, RJ45 cables for all 10/100/1000 Ethernet connections to protect the Acme Packet 4900 from potential damage.
  • To avoid making a complete circuit (which causes electrical shock), use only one hand when working with powered-on electrical equipment.
  • Use caution when using electrically conductive tools around the Acme Packet 4900.
  • Remove jewelry before working on the Acme Packet 4900.

Battery Warning

There is a risk of explosion if the battery is replaced by an incorrect type. Dispose of used batteries according to the instructions.

Perchlorate Material — Special handling may apply. See http://www.dtsc.ca.gov/hazardouswaste/perchlorate.

ESD Safety

To protect the Acme Packet 4900’s delicate electronic components from damage from static electricity, always follow the appropriate ESD procedures and wear the proper protective devices (such as an ESD wrist strap) when handling any and all Acme Packet 4900 hardware and while performing any Acme Packet 4900 hardware procedures.

Precautions

To protect your equipment from ESD, follow these ESD safety precautions:
  • Ensure that the Acme Packet 4900 is properly grounded.
  • If you are grounding your Acme Packet 4900 to an electrically conductive, grounded rack, check to see whether or not the rack is painted. Paint can hinder proper grounding. If your equipment rack is painted, you should ground the system to some other reliable place or remove a small portion of paint for proper grounding.
  • Use a grounded ESD wrist or ankle strap when working on the Acme Packet 4900 to prevent static discharge.
  • To avoid damaging ESD-sensitive hardware, discharge all static electricity from your body before working directly with the Acme Packet 4900 chassis by touching a grounded object.
