Step 4: Connect Cables

Required Tools and Wires for Cabling

Cabling your device takes only a few minutes. You need the following items for proper installation:

  • 1/8-inch flathead screwdriver.
  • 3/8-inch wrench or 3/8-inch nut-driver.
  • No. 2 Phillips screwdriver.
  • Ground wires—We recommend a minimum of 18-AWG ground wire for AC and DC-powered versions, if applicable.
  • Two #10 kep nuts (supplied) to connect the ground (earth) wire to the ground terminal.
  • Power module wiring—We recommend a minimum of 18-AWG wire for the device with a dual stud terminal lug with 5/8-inch spacing.

Consider the distance from the connection point and the configuration of the device when determining the size of wire used.

Connect the Management Console

The CONSOLE port on the front of the chassis of the CTP150 platform is for management access (see Figure 1). The 10/100Base-T Ethernet port accepts a male RJ-45 connector, providing an out-of-band connection for LAN access through an SSH session or SNMP.

The CONSOLE port is considered a data terminal equipment (DTE) interface. Direct connection to a terminal or PC (which also has a DTE interface) requires a crossover cable.

To connect the device to the network:

  1. Insert an RJ-45 Ethernet cable connector into the CONSOLE port until it clicks into place.
  2. Connect the other end of the cable to the appropriate Ethernet network for an out-of-band connection.

Connect the Timing Port

The CLK port on either of the interface modules is for an external network clock reference interface. Only one clock interface is needed for the device:

  • The serial interface module has an HD-26 CLK port (see Figure 3).
  • The T1/E1 interface module has an RJ-45 CLK port (see Figure 4).

On the CLK port, differential clock signals are output on the pins 4 and 17 of the HD-26 connector. When an EIA-530A DCE-F serial cable (CTP150-CBL-DB25-DCE-F) is connected to the CLK port, the TT pins 24 and 11 of the DB25 connector output clock signals. If you configure a 32 kHz reference output, an RS-422 32 kHz clock signal is generated on the pins. Even if you disable the 32 kHz reference output and configure an external clock reference, the module expects an RS-422 clock input (of the configured frequency) on the same pins.

To connect the clock source input ports:

  1. Attach the appropriate connector to the CLK port.
  2. Attach the opposite end of the network timing cable to your network's clock source A.

Connect the Serial Interface Module

The CTP150 platform serial interface module provides four HD-26 ports (see Figure 3). To install the cable in a port:

  1. Ground yourself by using an antistatic wrist strap or other device, and connect it to an ESD grounding jack, or to some other grounding device.
  2. Slide the cable as far as you can into the module until it clicks into place.
  3. Gently pull the cable to confirm that it is inserted correctly.

Connect the T1/E1 Interface Module

The CTP150 platform T1/E1 interface module provides four RJ-45 connector ports (see Figure 4). To install the cable in a port:

  1. Ground yourself by using an antistatic wrist strap or other device, and connect it to an ESD grounding jack, or to some other grounding device.
  2. Slide the cable as far as you can into the module until it clicks into place.
  3. Gently pull the cable to confirm that it is inserted correctly.
