Network Connections

This chapter describes how to connect the Switch as a standalone device or in a group to one or more SP-24 Switches. The Switch is provides the Ethernet over VDSL Uplink to the central office while the splitter combines the VDSL data channel and basic telephone services for transport to end users.

Network cable connections can be made to the Switch with the power on or off. Caution should always be used when working with or handling any electrically powered devices.

The cable connections described in detail in this chapter include:

Connections to the Switch

Switch-to-Switch connection via IEEE 1394 “FireWire” for multiple Switch installation

Switch to backbone; (VDSL over Ethernet) Uplink to backbone via RJ-45 Ethernet port

Switch to SP-24DSL Splitter via Telco50 cable (RJ-21 port)

Connections to SP-24DSL Splitter

Splitter to Switch or Switch pair via Telco50 (RJ-21 connector) cable

Splitter to CPE (via 0.4mm or 0.5mm twisted-pair telephone cabling)

Splitter to PBX (analog channel to Central Office) for basic telephone services

The Switch-to-computer connection via the RS-232 port (used for device/network management) is discussed in Chapter 5.

The devices described here are designed for installation in a standard 19” rack where cable connections can be easily accessed from both the front and the rear of the rack. Please read Chapter 2 for information about how to install the devices in an equipment rack. The cable connections are described in two sections, one for connections made using the ports on the front of the equipment and another for the connections made on the back.

Connecting Multiple Switches

Up to 6 Switches may be grouped in a stacked configuration and connected together using FireWire cabling. A multiple Switch arrangement can be connected to share a single uplink to the Ethernet backbone and be placed in a single 19” equipment rack. Stacked switch group interconnections use IEEE 1394 FireWire.

Note: IEEE 1394 “FireWire” is a serial bus technology defined by the IEEE1394 High Performance Serial Bus standard. For information about IEEE 1394, go to the 1394 Trade Association web site: http://www.1394ta.

Stacking a Switch Group

Up to 6 Switches may be stacked and managed as a unit with a single IP address and single uplink to the Ethernet backbone. If you use the stacking function, it is important that you understand how stacking works in the Switch, read Managing Switch Stacks and Determining Stack Order in Chapter 5 before placing the Switches in the rack. The auto-detect feature for establishing the stack hierarchy can be overridden, see Stacking Configuration in Chapter 6 for details on changing the stack order.

Figure 4-2 below illustrates how the Switch stack should be connected.
