TB9400 Installation and Operation Manual

© Tait Limited March 2015

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 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 sockets. This includes the Ethernet 
connector on the rear 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.

The operating temperature range of the equipment 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.

The humidity should not exceed 95% relative humidity through the 
specified operating temperature range.

For uncontrolled environments, the level of airborne particulates must not 
exceed 100µg/m
