Always check first. •Always connect the AC power cord to a properly grounded AC outlet to avoid damage to the system or injury. Warning Secure the power supply using a fastener or nearby shelf so that it does not hang from the power connector. Required Tools and Materials •If the unit is to be mounted on the wall: —1 Flat or Phillips screw driver —2 round or flat head Phillips or slotted screws - 1 . inch long —2 hollow wall anchors •If the unit will be mounted in a shelf: —1 Flat or Phillips screw driver •If the T1/E1 port will be used to connect to WAN: —T1 cable to connect the T1/E1 port to a T1 line. Warning To reduce the risk of fire, use only 26 AWG or larger wire (e.g. 24, 22, 20, etc.) to connect the T1 port on your unit to an RJ-45 jack. •Ethernet cables to connect the LAN ports to LAN switches or to individual IP phones. They can also be used to connect the Ethernet WAN port to a WAN router, a Cable Modem or a DSL Modem, if T1/E1 port is not being used to connect to the WAN. Desktop Installation 1.Remove the 4350 and accessories from the shipping container. 2.Place the 4350 on a flat, dry surface such as a desktop, shelf or tray. 3.Connect the power and network cables to the appropriate ports on the back of the system. Caution To reduce the risk of fire, use only 26 AWG or larger wire (e.g. 24, 22, 20, etc.) to connect the T1 port on your unit to an RJ-45 jack. Wall-Mount Installation 2.Install two screws 5.9" (150 mm) horizontally apart on a wall or other vertical surface. The screws should protrude from the wall so that you can fit the appliance between the head of the screw and the wall. If you install the screws in drywall, use hollow wall anchors to ensure that the unit does not pull from the wall due to prolonged strain from the cable and power connectors. 3.Remove the 4350 and accessories from the shipping container. 4.Mount the 4350 on the wall as shown below. 1.Connect the power and network cables to the appropriate ports on the back of the system. Warning Secure the power supply using a fastener or nearby shelf so that it does not hang from the power connector. Caution To reduce the risk of fire, use only 26 AWG or larger wire (e.g. 24, 22, 20, etc.) to connect the T1 port on your unit to an RJ-45 jack. Rack-Mount Installation 1.Attach the ear mounts to both sides of 4350 with the screws. 2.Attach the 4350 with the ear mounts to the shelf by screwing the ear mounts to the shelf with screws. Connecting the Power and Cables Warning Always connect the AC power cord to an AC outlet suitable for the power supply that came with the unit in order to reduce the risk of damage to it. •Connect one end of the AC power cord to the power adapter and the other one to the AC outlet. •Connect plug from the power adapter to the Power Connector on the 4350. Sometimes a little force is necessary to get the plug properly positioned Caution Secure the power adapter using a fastener or tie wrap to nearby shelf so that it does not hang from the power connecto...
