TB9100 Installation and Operation Manual General Safety and Regulatory Information 29

You can obtain further information on antistatic precautions and the dangers
of electrostatic discharge (ESD) from standards such as ANSI/ESD
S20.20-1999 or BS EN 100015-4 1994.
Anti-tampering
Devices
All network elements should be physically secured, where possible. This
includes the use of locked cabinets and the use of seals on connectors.
All network and audio connectors should be sealed with the stick on type
of seal. The purpose of the seals is to detect unauthorized tampering. The
seal should reveal if any of the connectors have been unplugged or if any
unauthorized equipment has been plugged in.
The seals must be difficult to remove without breaking, and must bridge
between the cable and equipment side (plug and socket) of the connection.
Seals must cover any unused network or audio sockets. This includes the
Ethernet connector on the front panel, any spare switch ports, and the
console port on the router and switch.
The seals must be difficult to reproduce. A sticker initialed or signed by the
technician should satisfy this.
Seals must be replaced if they need to be disturbed during maintenance.
Environmental Conditions
Operating
Temperature Range
The operating temperature range of the TB9100 is –22°F to + 140°F
(–30°C to + 60°C) ambient temperature. Ambient temperature is defined as
the temperature of the air at the intake to the cooling fans.
Humidity The humidity should not exceed 95% relative humidity through the
specified operating temperature range.
