Stage 3: Connecting the TSU to the Platform

This section describes the connections that must be made to the TSU (installed in a cabinet server) in order to check the installation.




	NOTE: This does NOT involve connecting the TSCs to the signaling network (which must be left as the last task before the TSU is put into service).For full details of the TSC connectors and cables required, refer to “TSC Connectors and Cables”.

The subsections below describe the connection procedure and provide cabling recommendations for connecting more than one TSU to the hosts of a 2-host platform.

Connection Procedures

In order to work through the connection procedures in this section, you may need to refer to the diagram in Figure 8-2 “TSU Rear Panel Connectors (AC Powered TSU)” below. This shows the connectors on the rear panel of the TSU . These include the TSC connectors (for connection to the signaling network), the LAN card connectors (for host connections), as well as the power supply connectors.

	NOTE: It is not possible to have a dual LAN connection between a TSU and a single server.

All the steps described below apply to both 1-host and 2-host platforms, unless marked as “2-host only”.

Connect to the Host(s)

To connect the TSU to the platform host(s):

Using the 1.5 m LAN cable (HP Part Number: 5063-1358), connect TSU slot L0 to the platform host contained in the same server cabinet as the TSU.
2-host only: Using the 6.5 m LAN cable (HP Part Number: 5063-1359), connect TSU slot L1 to the other platform host. Refer to “Cabling Recommendations for 2-Host Platforms” for advice on making host connections in a 2-host platform.
Label the cables, stating what they are (LAN) and where they connect to (L0, L1).

Connect the TSC Cables

The TSC cables connect the TSCs to the signaling network. At this stage, you can connect the TSC cables at the platform end but must NOT connect them at the network end. To do this:

Connect the cables to the TSU. If you are using the optional connection panel, connect the network end of the cables to the rear of the connection panel.
Label the cables, stating what they are (E1, T1, V.35) and where they connect to (TSC1, TSC2 and so on).




	CAUTION: Do NOT connect the TSC cables at the network end yet.

Connect to the Power Supply

Now power on the TSU by connecting it to a suitable power outlet. The unit can be powered from an AC or DC supply. Refer to “TSU Electrical and Environmental Specifications” for details of the required power supply.

Cabling Recommendations for 2-Host Platforms

The cabling recommendations below allow you to determine your TSU Id settings. The diagram in Figure 8-3 “Cabling Recommendations for Two TSUs” shows an example for two TSUs.

The HSC/PCI LAN cards use the same slots in the two systems; that is, they have the same hardware path.
The HSC/PCI LAN ports connected to the same TSU have the same hardware path on the two hosts.
On each system, half of the TSUs are connected to the LAN port provided by the SS7 interface controller card of the TSU. The other half are provided by the LAN port on the add-on LAN card.

When these recommendations are followed, the TSU Ids are set in the order that the LANs are discovered by the auto-discovery function.
