Cisco AS5850 Universal Gateway Regulatory Compliance and Safety Information

OL-10265-01

Safety Guidelines

The primary function of the port card is to convert pulse code modulation (PCM) analog bitstreams to

digital data. This is done by use of service provider elements (SPEs) and their associated firmware that

perform the modulation and demodulation of six analog bitstreams each. T3 trunk cards have 36 SPEs

each, and the UPC has 54 SPEs.

The port card forwards the converted and packetized data to the route switch controller (RSC). From the

RSC, the data is routed to the external network through Gigabit Ethernet interfaces.

Working with Lasers

• Fiber-optic ports are considered Class 1 laser or Class 1 LED ports.

• These products have been tested and found to comply with Class 1 limits of IEC 60825-1, IEC

60825-2, EN 60825-1, EN 60825-2, and 21CFR1040.

• To avoid exposure to radiation, do not stare into the aperture of a fiber-optic port. Invisible radiation

might be emitted from the aperture of the port when no fiber cable is connected.

Table 1 shows the Class 1 laser label on the AS5850.

Power Shelf

The AC-input power shelf is provided with three IEC 60320 Type C20 power inlets. If you are not using

one of the standard Cisco power cords designated for your country, please choose one that has an IEC

60320 Type C19 connector on one end and the appropriate country-specific plug on the other end. The

power cord should be rated at least 15 A at low voltages (100 to 120 VAC) and at least 10 A at high

voltages (200-240 VAC).

Safety Guidelines

This section provides safety guidelines to help you avoid injury to yourself and avoid damage to the

equipment. The following safety guidelines are recommended when working with any equipment that

connects to electrical power or telephone wiring:

• Locate the emergency power-off switch for the room in which you are working before beginning any

procedures requiring access to the chassis interior.

• Disconnect all power and external cables before moving a chassis.

• Never work alone if potentially hazardous conditions exist.

• Never assume that power has been disconnected from a circuit; always check.

• Never perform any action that creates a potential hazard to people or makes the equipment unsafe.

• Carefully examine your work area for possible hazards such as moist floors, ungrounded power

extension cables, and missing safety grounds.
