Installing the IpChannel Bank 28
SmartNode 4400 Series Getting Started Guide 3 • Hardware installation
Connecting cables
This section describes installing the interface, power, and ground cables in the following order:
1. Installing the RJ-11 voice port (FXS) cable or cables (see section “Connecting the FXS ports” on page 28)
2. Installing the 10/100 Ethernet port cable (see section “Connecting the Ethernet ports” on page 28)
3. Installing the RS-232 console cable (see section “Connecting the EIA-561 RS-232 configuration port
(DCE configured)” on page 30)
4. Installing the power input (see section “Connecting power” on page 30)
Connecting the FXS ports
The remote FXO devices are connected to the IpChannel Bank via the RJ-21X cable. Consult Appendix C on
page 55 in order to connect the FXO devices to the selected FXS port on the IpChannel Bank.
1. Connect the RJ-21X connector of the cable into the 64-pin or 50-pin RJ-21X receptacle on the IpChannel
Bank. The pin count will depend on the IpChannel Bank that you ordered.
2. The other end of the cable has 25 non-terminated twisted-pairs for connection to punch-down blocks.
Select the twisted-pairs which will be used for
3. Select and attach the appropriate twisted-pair from each FXO device on punch-down blocks for connec-
tion to the chosen port on the IpChannel Bank.
Connecting the Ethernet ports
The IpChannel Bank has dual 10/100 Ethernet interfaces. One is for the WAN connection. The other is for
connecting to your Ethernet LAN. The Ethernet ports will auto-sense the correct speed of the local LAN and
automatically negotiate to half- or full-duplex operation. This section describes connecting the IpChannel
Bank to the Ethernet LAN via an Ethernet hub or switch.
The Interconnecting cables must be acceptable for external use
and must be rated for the proper application with respect to volt-
age, current, anticipated temperature, flammability, and
mechanical serviceability.
Do not work on the system or connect or disconnect cables during periods of
lightning activity.
