General safety practices
The equipment discussed in this document may require tools designed for the purpose being described. RLH
recommends that service personnel be familiar with the correct handling and use of any installation equipment
used, and follow all safety precautions including the use of protective personal equipment as required.
Caution - Severe Shock Hazard
•
Never install during a lightning storm or where unsafe high voltages are present.
•
Active T1 lines carry high DC voltages up to 130V. Use caution when handling T1 wiring.
•
Active HDSL lines carry high DC voltages up to 210V. Use caution when handling HDSL wiring.
Warning
The intra-building port(s) of the equipment or subassembly is suitable for connection to intrabuilding or
unexposed wiring or cabling only. The intra-building port(s) of the equipment MUST NOT be metallically
connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-
building interfaces only (Type 4 ports as described in GR-1089-CORE, Issue 4) and require isolation from the
exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these
interfaces metallically to OSP wiring.
Special handling requirements
Be careful when handling electronic components
This card utilizes circuitry that can be damaged by static electricity. When transporting the card, carry it in an
ESD safe container such as the antistatic bag provided with the card. There are no user serviceable parts on the
card. Do not open or remove the housing or insert tools or other objects into any openings except to access
switches or where otherwise intended. Doing so may permanently damage the card.
Guidelines for handling terminated fiber cable
"
•
Do not bend fiber cable sharply. Use gradual and smooth bends to avoid damaging glass fiber.
•
Keep dust caps on fiber optic connectors at all times when disconnected.
•
Do not remove dust caps from unused fiber.
•
Keep fiber ends and fiber connectors clean and free from dust, dirt and debris. Contamination will cause signal loss.
•
Do not touch fiber ends.
•
Store excess fiber on housing spools or fiber spools at site
