Personal Safety The following pages describe common practices concerning electrical safety, ergonomics, and rack installation. ■ Safety Precautions WARNING: Potential injury: On-the-job safety is important; therefore, observe the following safety precautions while you are engaging in any maintenance activity. Failing to follow these precautions could result in serious injury. Remove all conductive jewelry, such as watches and rings, before you service powered-on equipment. • Avoid electrical shock.
Lifting Techniques Lifting, regardless of how much or how little, can create serious back stress. If you follow these guidelines, you can reduce the risk of back injury: • Do not twist your body to pick up something or to put it down. Twisting puts extreme pressure on your back, especially when you lift or carry objects. Instead of twisting, make the task two separate moves; first lift, and then use your feet to turn your body.
■ Rack Safety and Precautions WARNING: Possible personal injury: • Lifting hazard: The library (with drives) weighs approximately 29 kg (64 lb). Use at least two people and a mechanical device to lift and position the library. Make sure you read the information in “Lifting Techniques” on page xviii before beginning. • Also consider the library’s total weight when you are placing other equipment into the rack.
■ Fiber-optic Safety WARNING: Eye hazard. Never look directly into a fiber-optic cable, a fiber-optic connector, or a laser transceiver module. Hazardous conditions might exist from laser power levels that are capable of causing injury to the eye. Be especially careful when using optical instruments with this equipment. Such instruments might increase the likelihood of eye injury. The laser transceivers in fiber-optic equipment can pose dangers to personal safety.
Product Precautions The following pages describe common practices concerning fiber optics and electrostatic discharge. Fiber-optic Cable Installation Follow these guidelines when you install fiber-optic cables: 1. Cable routing: • Raised floor: You may install fiber-optic cables under a raised floor. Route them away from any obstruction, such as existing cables or other equipment. • Cable tray or raceway: Place the cables in position; do not pull them through the cable tray.
Fiber-optic Cable Handling Observe these precautions when you handle fiber-optic cables: • Do not coil the cable to less than 96 mm (3.75 in.) in diameter. • Do not bend the cable to less than 12 mm (0.5 in.) in radius. It is most important that a cable’s bend radius be no less than 20 times the diameter of the cable. • Do not pull on the cables; carefully place them into position.
• Reinstall all equipment covers and close all equipment doors after you have completed the work. • If the grounding-kit work surface has been exposed to temperatures above 66ºC (150ºF) or below 4.5ºC (40ºF), acclimate the work surface to room temperature before you unroll it. • Immediately place any component that you have removed into an ESD-protective package. • Keep the grounding-kit work surface clean.
a. If you are working on components from a small piece of equipment, attach the free end of the coil cord to the grounding-kit work surface. In addition, be sure that you touch an unpainted metal surface on the equipment before you touch an internal component. b. If you are working on components from a large piece of equipment, attach the free end of the coil cord to a grounding jack or to an unpainted metal surface inside the equipment. Replace Components 7.
