FastPADmp12 Hardware

FastPADmp12 Hardware

This chapter describes the FastPADmp12 front panel, rear panel, and processor board.

The FastPADmp12 is a stand-alone product providing 12 lines, just like the mp, but is a more powerful device. When the mp12 is rack-mounted, it functions as one logical unit providing 36 ports.

The FastPAD mp12 can provide 12 lines (L0-L11) or 36 lines (L0-L35). It can handle speeds up to E1.

FastPADmp12 Front Panel

Figure 3-1 shows the FastPADmp12 front panel. The front panel is similar to the mp's front panel. Refer to the section "FastPADmp Front Panel" in the chapter "FastPADmp Hardware Description" for details.

Processor Board

The FastPADmp12, like the mp, is designed around a motherboard—MPB—and a daughterboard—MTB.

Figure 3-2 illustrates the MPB, MTB and jumper positions.


Figure 3-2: FastPADmp12 Processor Board


The meaning on the jumpers on the MPB is the same as for the mp. (See Table 3-1.)

FastPADmp12 Rear Panel

This section describes the FastPADmp12 rear panel connectors and power supply.

Line Connectors

The FastPAD mp12 rear panel or ViB12T board has 12 DB-25 female connectors for 12 lines numbered from L0-L11.

Figure 3-3 illustrates the ViB12T.


Figure 3-3: FastPADmp12 Rear Panel


Jumpers

On the rear panel, blue jumpers refer to TB2. For a stand-alone mp12, these jumpers are illustrated in Figure 3-4.

Power Supply

All stand-alone FastPADmp12 devices include a power supply on the rear panel of the module. Stand-alone power supplies have an on/off switch and a fuse. Rack-mounted models receive power from a power supply built into the rack.

The power supply is attached to the ViB12T board by a screw (see Figure 3-3) and two clips (see Figure 3-5). See the appendix "Specifications" for specifications.


Figure 3-5: FastPADmp12 Power Supply


Installation

This procedure is the same as for an mp. Refer to the section "Installation" in the chapter "FastPADmp Hardware Description."

Shelf

The mp12 has a transputer on the MTB board, which is why the mp12 can be used as a multimodule system. In a shelf, up to three FastPADmp12 modules can be interconnected to form a logical unit with 36 ports. Each FastPADmp12 is then called a module and uses a module number.

Modules are interconnected using link connector A and B on the ViB12T board. The link between modules is called an Inter-Module Link (IML). IMLs are high-speed links (20 Mb/s) managed by transputer.

Figure 3-6 illustrates the rear of a unit.


Figure 3-6: FastPADmp12 Rear View

Rear Panel

The shelf is shipped with the rear panel already attached. The rear panel is composed of three ViB12T boards interconnected with the IML connector, already attached. It provides 36 physical ports.

IML Connector

In front of the rear panel, from the right to the left, there are: Module 0, Module 1,
Module 2. Link A, on each ViB12T is now available, since there is no more power supply connected.

Warning Never remove the IML Connector while the unit is powered up.

TB2 Jumpers

The TB2 jumper settings in Module 0 are shown in Figure 3-7.


Figure 3-7: Module 0 TB2 Jumper Settings

The M1 and M2 jumper settings are the same as for a stand-alone (see Figure 3-8).


Figure 3-8: M1 and M2 Jumper Settings

Line Connectors

A unit based on three FastPAD mp12 provides 36 ports (3x12). As the rear panel is based on the ViB12T, lines are numbered from L0-L11, modulo 12.

For example:

Line 12 is line 0 of Module 1
Line 15 is line 3 of Module 1
Line 24 is line 0 on Module 2

Packing List

Steps

Note If the FastPAD is a FRAD, we recommend that you use Lines L1, L2, or L4 for the main trunk line. If the FastPAD is an X.25 feeder switch, use Lines L0, L3. These recommendations are made for Default Configuration reasons (see the FastPAD Configuration Manual).

First, install the shelf (see the chapter "Overview"). Take the following steps to check power compatibility:

Step 1   Attach termination on Link B on Module 2 on the rear panel.

Step 2   Check the IML connection and TB2 Jumper position.

Step 3   Insert the SmartCard in the front panel opening of the module.

Step 4   Set the Interface Card according to your needs. (See the chapter "Interface Cards.")

Step 5   Insert the module in the rack.

Step 6   Wait for the autotest, approximately two minutes.

Step 7   The equipment is operational and in default configuration (see Table 3-3).

Step 8   Connect a terminal on the front panel (OPALE) or on port 5 (modulo 12) to access the configuration function. Refer to the FastPAD Configuration Manual for more details.
