Description

The M12-100T is a 10BASE-T/100BASE-TX Fast Ethernet DomainX module for insertion into the Avaya M770. It provides connection for 10/100M Ethernet servers and end stations.

The Avaya M770 supports two Frame Switches, named DomainXs: DomainXL

(Left DomainX) spans slots 1-7, and DomainXR (Right DomainX) spans slots 8-14.

Each DomainX supports up to 6 Gbytes of bandwidth. You can insert the

M12-100T into either DomainX, provided you don’t exceed the maximum of 100

Domain Resource Units (DRUs) per DomainX. Each module uses a certain number of DRUs; the M12-100T uses 18 DRUs.

Each of the module’s 12 ports can work at 10BASE-T/100BASE-TX speed. Each port can also be configured to function in either half or full duplex speed. You can specify for each port the 10/100M speed and half/full duplex, or choose to use auto-negotiation. Auto-negotiation automatically determines the individual port’s optimal mode of operation - 10/100M speed and half/full duplex.

In addition, Avaya’s top-performing congestion management means that no packets are lost, reducing the need for bandwidth-wasting retransmission.

The M12-100T is manageable under CajunView™, Avaya’s family of SNMP network management systems, or any other SNMP-based management system.

Installation

Installation Overview

There are several stages involved in the installation of the M12-100T:

• Hardware Configuration: Setting operation parameters via DIP switches on the module’s circuit board.

• Domain Usage Considerations: Computing whether your intended configuration fits the Avaya M770 domain resources.

• Installing the Module: Inserting the module in the Avaya M770 hub, and connecting cables to the module’s ports for connection to other equipment: switch, hub or station.

Caution:

The M12-100T contains components sensitive to electrostatic discharge.

To prevent ESD damage, always hold the card by its sides only, and do not touch the circuit board components unless instructed to do so.

Before handling the module or inserting it in the hub, touch the chassis of the hub to discharge any electrostatic charge on your body.

Note:

The recommended Avaya M770 configuration is two M-PS500 units, plus a third unit for redundancy. Such a configuration supports any number of

DomainX and Avaya M400 Gate Switch Modules in the hub.

If there is only one M-PS500 unit available, the maximum number of modules in the hub is based on the following guidelines:

• 5 or less DomainX modules, or

• 4 or less DomainX modules with 2 or less Avaya M400 modules, or

• 3 or less DomainX modules with 5 or less Avaya M400 modules.

Hardware Configuration

Before installing the M12-100T module in the hub, you must configure the hardware by setting the appropriate DIP switches on the main and upper circuit boards. The following diagram shows the position of switches on the circuit boards. The illustration is oriented with backplane connectors to the right.

Chapter 2 Installation

Domain Usage Considerations

The M12-100T is a DomainX module of the Avaya M770. The maximum number of

DomainX modules you can insert in the hub is determined by domain usage considerations, as follows (M-SPV refers to either the M-SPV or the M-SPX in the following examples):

The Avaya M770 allows a maximum of 100 Domain Resource Units (DRUs) for

DomainXL (Left DomainX - slots 1-7) and the M-SPV, and 100 DRUs for

DomainXR (Right DomainX - slots 8-14) and the M-SPV. Each of the DomainX modules, as well as the M-SPV module, has a DRU budget, as shown in the table below. When planning your hub configuration, calculate whether it fits the

Avaya M770 DRU budget.

Table 5 Avaya M770 Module DRU Budget

Module Name DRU Budget

Budget Calculation Examples

1. If you have six M14-10F modules, an M2-1000 module and the M-SPV you get:

6*6+15+10 = 61 DRUs. Assuming that you have the same configuration on the

DomainXL and Domain XR switches you get a total of 168 Ethernet, 12 Fast

Ethernet and 4 Gigabit ports.

2. If you have five M12-100 modules and the M-SPV you get: 5*18+10 = 100

DRUs. Assuming that there are five modules on both the DomainXL and

Domain XR switches you get a total of 120 ports.

3. If you have six M2-1000 modules and the M-SPV you get: 6*15+10=100 DRUs.

Assuming that there are six modules on both the DomainXL and Domain XR switches you get a total of 24 Gigabit Ethernet ports and 72 Fast Ethernet ports.

4. If you have four M12-100 modules, one M2-1000 and the M-SPV you get:

4*18+15+10=97 DRUs. This is less than 100 DRUs and is therefore another possible configuration.

Note: A redundant M-SPV does not count in the DRU calculations. However you must include the active M-SPV twice, once for DomainXL and once for

DomainXR.

DRU Budget Information Window

You can check the DRU budget information for your Avaya M770 hub via the

CajunView  Network Management System (NMS). The following window shows an example of a hub with an M-SPV, 2 M12-100T and an M12-100F module.

Chapter 2 Installation

Installing the Module

The M12-100T occupies one slot in the Avaya M770 chassis and can be inserted into any available position.

The M12-100T can be installed or removed while power on.

To install the M12-100T:

• Hold the module (shaped like an upside down L) using both hands. The colored module name panel and LEDs should be on top (see Figure 3).

• Fold out the plastic handles on the top and bottom of the front panel.

• While holding the module by its handles, place it onto the top and bottom guide rails in the hub and gently slide it in.

• Plug in the module by pressing firmly on the mid-section of the front panel.

Fold down the handles and secure the module using the two screws at the top and bottom of the front panel. Do not over-tighten the screws.

Note: Even though the modules are hot-swappable a short self initialization period is required when inserting or removing them from the hub. Allow at least

5 seconds initialization time between modules when inserting or removing several modules.
