Incoming Signals

An incoming signal is only visible on the front panel if it is monitored by the configuration; if the user has not configured the module to monitor that particular signal, the LED corresponding to the signal remains unlit (even if the LED is part of the LED state depicting In Service).
In the case of a network management link (DTE line), monitoring of signals is independent from the configuration; the signals monitored in this case are the following:

: Asynchronous line: 142 only
Asynchronous line: 142 and 106

Incoming Signals DTE: 106, 107, 109 and 142.
Incoming Signals DCE: 105 and 108.

Note See Table 2-3 for signal definitions.

Outgoing Signals

Outgoing signals 108 (DTE), 106 (DCE) and 109 (DCE) are positioned on the link in function of parameter 26 in class 12. They are present on the front panel if they are actually emitted at the link.
Outgoing signals 105 (DTE) and 109 (DCE) are generated directly by the user and their appearance on the front panel directly depends on the value entered for parameter 26.
Outgoing signals DTE: 105 and 108.
Outgoing signals DCE: 106, 107 and 109.

Table 2-6 and Table 2-7 illustrate signal activity on the front panel during network management.

Note See Table 2-3 for signal definitions.

Reset a Selected Line (D + Select, then Line No. + Select)

Resetting a line clears any virtual circuits on the line, flushes any data associated with the line, and resets line signals. To reset a selected line:

Step 1 Rotate the thumbwheel until "D" is displayed.

Step 2 Press the Select switch.

Step 3 Rotate the thumbwheel until the desired line number is displayed.

Step 4 Press the Select switch.

See Figure 2-2.

Software Restart (E + Select)

Restarting the system software re-initializes all software functions without executing system autotests. The recovery time is about 30 seconds. To reset system software:

Step 1 Rotate the thumbwheel until "E" is displayed.

Step 2 Press the Select switch.

After pressing the Select switch, software restart is carried out. There is a small window of time, about five seconds per setting, during which YOU CAN:

Choose Restart Configuration
Assign Module Number

See Figure 2-2.

Figure 2-2: Front Panel Switches

Defining the Configuration for Restart (E + Select, Option + Select)

Select "E" on the thumbwheel and confirm with the Select switch.

There is a window of time of about five seconds during which you can set the thumbwheel switch to the desired number (8, 9, 10 or 11). When the Power LED is flashing (RED/GREEN) and other LEDs are lit (this happens during the five-second window), you confirm your choice with the select Switch. (See Table 2-8.)

Thumbwheel switch	Restart Configuration
E + 8	Copy the default configuration into the user configuration and restart with this configuration and operating system.
E + 9	Copy the SmartCard configuration into the user configuration and restart with the operating system.
E + 10	Start up with the operating system and default configuration.
E + 11	Start up with the operating system and the previous user configuration.
C	Start up with boot program (reserved).

Steps

Step 1 E + Select —> Software Restart.

Choose your desired option (8, 9, 10, 11) by setting the thumbwheel at the correct position.

Step 2 Power LED flashes RED/GREEN and other LEDs are lit.

The time window is approximately five seconds.

Step 3 Confirm your selection in Step 2 with the Select switch.

¹Coded in binary-coded decimal on LEDs.

Note A module coming from the factory is able to deduce its own position within the unit.

Note Even if the user does not choose to have the mp use a module number, assigning module numbers is nonetheless explained here. The reason for this is later descriptions of the mp12 and mprxx refer the reader to this section for details, because their front panels are identical to that of the mp and function in the same way.

Hardware Reset (F + Select)

Resetting the hardware runs the complete set of hardware start-up autotests, and re-starts the unit with operational software and the user configuration. Recovery time is about 2 ms. To reset the hardware:

Step 1 Rotate the thumbwheel until "F" is displayed.

Step 2 Press the Select switch.

DIN

Refer to the section "DIN Connector" in the chapter "Overview."

SmartCard

Refer to the section "mp, mp12 and mprxx SmartCard" in the chapter "Overview."

Processor Board

The FastPAD mp is designed around a motherboard called MPB (Medium Processor Board) and a daughterboard called MTB (Memory and Transputer Board). (See Figure 2-3.) In the case of the FastPADmp, there is no transputer on the MTB. Thus, an mp is always a single node (one in stand-alone, of course, or up to three different nodes if rack-mounted).

Note The front panel is attached to the MPB.

The mp is a hot swappable device.
On the MPB, there are four jumpers.

Figure 2-3: FastPADmp Processor Board

The jumper settings for the MPB are listed in Table 2-11.

Jumper	Default setting
TB1	Position A (reserved)
TB2	Position NOT LWD (reserved)
TB3	Position NOT ABORT (reserved)
TB4	Authorizes a reset of hardware (Thumbwheel set to "F", front panel "Select" button depressed)

FastPADmp Rear Panel

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

Line Connectors

The FastPADmp rear panel or ViB12 board has twelve DB-25 Pin female connectors for twelve lines numbered from (L0 - L11). Figure 2-4 illustrates the ViB12.

Figure 2-4: FastPADmp Rear Panel

Power Supply

All stand-alone FastPADmp 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 ViB12 board by a screw (see Figure 2-4) and two clips (see Figure 2-5). See the appendix "Specifications" for specifications.

Figure 2-5: FastPADmp12 Power Supply

Installation

There is one box containing the mp module.

Tools

You need an Allen wrench, which is supplied with the equipment. Before starting, check power compatibility.

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 or L3 for the main trunk line. These recommendations are made for Default Configuration reasons (refer to the FastPAD Configuration Manual).

Step 1 Unscrew the Allen screw on the front panel.

Step 2 Remove the mp from the case. The front panel and the processor board are one piece.

Step 3 Set the interface card and jumpers according to your needs. (Refer to the chapter "Interface Cards.")

Step 4 Reinsert the mp into the case.

Step 5 Insert the Smartcard in the module front panel opening.

Step 6 Screw in the Allen screw.

Step 7 Turn ON the power switch.

Step 8 Wait for the autotest, approximately two minutes.

Step 9 The equipment is operational in default configuration:

Power	1	2
Green	Orange	Green

Step 10 Use a terminal connected to the front panel (OPALE cable) or on port 5 to access the configuration function. Refer to the configuration manual for details.

Grouping mps Together in a Shelf

An mp can be rack-mounted on a shelf. A shelf can house up to three mp modules. (See Figure 2-6.) Since an mp has no transputer, these three mp modules are independent and function as three different nodes. They have three different configurations.

Step 1 Install the shelf, as described in the chapter "Overview."

Step 2 The rear panel of the shelf consists of three ViB12 boards (same as for a stand-alone).

Step 3 Set the interface card on the mp according to your needs.

Step 4 Insert the mp module.

Step 5 The physical position of the mp module within the shelf is marked on the label located on the module front panel.
