NetComm NCT240 Installation Guide Release 1.0 4. Installation Procedure Equipment Checklist Before installing the access switch please verify that you have received all the items listed under “Package Contents.” If any of the items are missing or damaged, contact your local distributor. Also, be sure you have all the necessary tools and cabling before installing the switch and splitter. Note that these devices can be installed on any suitably large flat surface or in a standard EIA 19-inch rack.
NetComm NCT240 Installation Guide Release 1.0 Mounting The NCT240 may be mounted on any flat surface, such as a shelf, or in a rack. Before you start installing the access switch, make sure you can provide the right operating environment, including power requirements, sufficient physical space, and proximity to other network devices that are to be connected. Verify the following installation requirements: • Power requirements: 100 to 240 VAC (± 10%) at 50 to 60 Hz (± 3 Hz).
NetComm NCT240 Installation Guide Release 1.0 Installing Optional Modules Before mounting the switch, be sure you install any optional modules. If you have purchased an optional slide-in 1000BASE-T, SFP 1000BASE-X, install it now, and following the instructions below. To rack-mount devices: 1. Attach the brackets to the device using the screws provided in the Bracket Mounting Kit. Figure 4-1. Attaching the Brackets 2. Mount the device in the rack, using four rack-mounting screws.
NetComm NCT240 Installation Guide Release 1.0 Figure 4-2. Installing the Switch in a Rack 3. If installing a single switch only, turn to “Powering On the Switch” at the end of this chapter. 4. If installing several devices, we recommend using one stack for the switch, and another for the others. This will keep the cabling straight and easy to maintain.

NetComm NCT240 Installation Guide Release 1.0 Proper grounding (earth) Proper Grounding is a very important part of the electrical installation for NCT240, if noise is present in the Electrical ground this noise can leak to the ADSL circuit through the Surge protectors and interfere with the proper operation of ADSL links. *** both AC/DC power supplies are isolated from the NCT240 ground therefore the Grounding procedure is the same regardless of what the power supply is .
NetComm NCT240 Installation Guide Release 1.0 Installing an SFP Transceiver NCT240 Figure 4-5. Inserting an SFP Transceiver into the Slot To install an SFP transceiver, do the following: 1. Use your cabling requirements to select an appropriate SFP transceiver type. 2. Insert the transceiver with the LC connector facing outward and the slot connector facing down. Note: SFP transceivers are keyed so they can only be installed in one orientation. 3.
NetComm NCT240 Installation Guide Release 1.0 Connecting RJ-21 Cables For incoming phone lines, a splitter can connect directly to a PBX or can be connected via a punch-down block. The particular connection method used will depend on the type of connectors and cables supported on the PBX, and on the existing cabling in the building. The EE lines from the splitter interface of NCT240 are connected to the punch-down block that connects the phone lines that run up to the end users.
