# Cabling the System

Cabling the system requires the following main tasks:

1. Familiarize yourself with the ports, and ensure that you have the cables and wires needed to complete each cabling procedure.
2. Read and understand all safety warnings. (See Installation Guidelines and Requirements.)
3. Connect the system to the network and to a management console.
4. Connect the other interfaces to their appropriate network interface.
5. Connect the power cables from the power source to the system's power supply.

   | Note: We recommend that you use shielded cables where appropriate.

See System Specifications for more information about system specifications.

## Cabling the Management Console

Before powering up the system, you must set up a management console. The console enables you to communicate with your system during the power-up process and to manage your system using the command-line interface (CLI).

When connecting a console directly to the system, use a cable appropriate for your terminal connector. The cable must have a female DB-9 connector to attach to the RS-232 port on the system.

### Management Ports

The management section of the system has three ports for management access (see Figure 7 and Figure 9):

- Two 10/100Base-T Ethernet ports—Each accepts an RJ-45 (male) connector, providing an out-of-band connection for LAN access through a Telnet session, SSH, or SNMP.
- One RS-232 management port—Accepts a DB-9 (female) connector. This port provides direct CLI access from a console terminal.

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

See Setting the Initial Configuration for more information about management access.

#### Connecting to the Network

To connect the system to the network:

1. Insert an Ethernet cable (RJ-45) connector into the 10/100Base-T (RJ-45) port on the system until it clicks into place.
2. Connect the other end of the cable to the appropriate Ethernet network for an out-of-band connection.

#### Connecting to a Console Terminal

When you connect a console directly to the system, use a cable appropriate for your terminal connector. The cable must have a female DB-9 connector to attach to the RS-232 port on the system.

To connect the console:

1. Insert the female DB-9 connector into the RS-232 port, and tighten the screws.
2. Connect the other end of the cable to your terminal's serial port (VT100/ANSI).

## Cabling Ethernet Interfaces

Port ETH0 and ETH1 on the C2000 model and the C4000 model accept RJ-45 10/100/1000Base-T Ethernet (copper) interfaces. Port ETH2 and port ETH3 on the C2000 model and the C4000 model accept SFPs.

## Cabling the System for Power

After you have correctly cabled the system, you can then attach the power cord. See Figure 8 and Figure 10. See System Specifications for the power requirements for the system.

To cable the system for power:

1. Insert the power cord into the AC power IEC receptacle.
2. Insert the other end of the power cord into an appropriate AC power source.

   | Note: We suggest that you use an uninterruptible power supply (UPS) with your C Series Controller.

   | Note: To provide redundancy, do not terminate Power A and Power B leads at the same power source.
