WARNING: Only trained and qualified personnel should install, replace, or
service this equipment. Disconnect the system before servicing.
Read all of the installation instructions before you connect the system to its power
source.
Never touch uninsulated telephone wires or terminals unless the telephone line
has been disconnected at the network interface.
The TippingPoint X506 uses double pole/neutral fusing. Use caution when
servicing this product.
For protection against fire on the TippingPoint X506, use replacement fuses with
the following type and rating only: 5x20 mm, 2a, 250 volts, fast acting.
Do not operate the system unless all faceplates and covers are in place.
Faceplates and cover panels serve three important functions: they prevent
exposure to hazardous voltages and currents inside the chassis; they contain
electromagnetic interference (EMI) that could disrupt other equipment; and they
direct the flow of cooling air through the chassis.
To prevent personal injury or damage to the chassis, lift the chassis from
underneath its lower edge.
Enclosed racks may have higher ambient temperatures than open racks. Ensure
enclosed racks ambient temperatures do not exceed maximum recommended
ambient temperature of 104
°F (40 °C).
