# Cabling Overview

Cabling the router requires the following main tasks:

1. Familiarize yourself with the module ports, and ensure that you have the cables and wires needed to complete each cabling procedure. (See Figure 25.)
2. Read and understand all safety warnings. (See Installation Guidelines and Requirements.)
3. (Optional) Connect timing ports.
4. Connect the SRP IOA to the network and to a management console.
5. Connect grounding wires to the router chassis.
6. Connect the power cables from the power source to the power distribution unit (PDU).
7. Connect the IOAs to their appropriate network interface.
