1.2 Installation Prerequisites
In order for the Tmedia system installation to proceed without interruption, it is important that you verify
that you have on hand all of the necessary materials. Prior to beginning the installation, you should
have prepared for the following:
• Adequate space for the installation of your Tmedia system. Consider that you will need to mount
the Tmedia units on one or more 19” customer-provided equipment racks.
• Adequate power supply and power connections. In order to guarantee an uninterrupted supply, the
Tmedia units must be powered by a dedicated power source. Consider that each Tmedia unit will
require one to two power connections in addition to PCs, servers, and Ethernet switches. Tmedia
units (other than 2U DC-powered units) are not shipped with power cords and therefore you will
need to plan for your power cable requirements.
• In order to run your telecom applications on the TMP6400, you will need to have purchased an
adequate number of licenses for the features that you will use.
In addition, you will need the following equipment:
Gigabit Ethernet Switches
Two gigabit Ethernet switches must be used to support full control redundancy. In its lab studies,
TelcoBridges has not encountered problems with a large variety of switches available in the market. The
following is a list of some switches that TelcoBridges has used:
• Dell Powerconnect 2708, 8 gigabit Ethernet ports
• Dell Powerconnect 2716, 16 gigabit Ethernet ports
• Netgear GSM7324, Layer 3 managed, 24 gigabit Ethernet ports
1.3 Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It may occur if
electronic printed circuit cards are improperly handled and may cause complete or intermittent failure.
Attention
Always follow ESD prevention procedures when removing and replacing modules:
• Ensure that the TelcoBridges Tmedia units are electrically connected to earth ground.
• Wear an ESD-preventive wrist strap and ensure that it makes good contact with your
skin. Connect the wrist strap clip to an unpainted surface of the Tmedia unit or the
grounded equipment rack in order to channel away all ESD voltage safely to ground.
To guard against ESD damage and shocks, the wrist strap and cord must be in proper
working condition.
• If no wrist strap is available, and you must work with the Tmedia units, ground yourself
by touching a metal part of the chassis.
