2.3. Electrical Safety Guidelines
Warning: Connect power only after all network and antenna cable
connections are performed. Powering the device before connecting, for
example, the external antenna, can lead to irreversible device damage.
Warning: To prevent short-circuiting and electrical shocks, cables with
exposed ends (i.e. not yet crimped) should be covered with protective
polythene bags during external cable installation processes.
2.3.1. Handling Electrostatic Devices
Warning: To prevent ESD damage to ASWipLL devices, always wear an ESD
wrist strap when handling these devices or coming into contact with internal
components.
Electrostatic devices are those devices that may be damaged by the inadvertent
discharge of static electricity from a charged body. The risk of damage, due to
electrostatic discharge (ESD) to a device, may cause the device to fail suddenly, or it
may induce a partial defect within the device, which will cause subsequent
premature failure. Static electricity can result from operators walking on floors,
moving around on chairs, from the movement of operator's clothing or even casual
brushing against racks, benches or walls.
Airspan recommends the following guidelines to be adopted to minimize the risk of
component failure due to electrostatic discharge to the device:
„ ASWipLL devices are provided typically in see-through anti-static bags.
Wherever possible, checking and inspection of a unit should occur without
removing it from the bag.
„ Where operators come into direct contact with any piece of electronic hardware,
operators must wear an
ESD-preventive wrist strap . All straps and cords
should be tested using a Wrist Strap Tester prior to use. The wrist strap cords
shall have a 2 Meg Ohm resistor fitted at either end. Wrist straps should be worn
in direct contact with bare skin and not over clothing.
