Quick Start

To start using the Avaya M770, plug in at least one Power Supply unit and at least
one M-SPV/M-SPX (Avaya M770 supervisor) module into the rear of the chassis,
and switch the Power Supply ON. The Avaya M770 requires at least one 500W PSU
(M-PS500) and one M-SPV/M-SPX module. To use it as is, simply connect the PSU
to a suitable power source.

Note: The Cable Manager panel is packed separately in order to protect the cable
manager. Please refer to Installing the Cable Manager below for details.

If you are installing the Avaya M770 in a rack, you can adjust the depth by fixing the
enclosed Rack Mount plates (refer to Installing the Depth-Adjusting Plates below).
You must install the plates before inserting modules since the installation requires
work inside the hub.

Installing the Cable Manager

The Avaya M770 hub is packaged with a blank panel affixed to the base of the front
of the hub. You can pull off the blank panel (unclip it) and replace it with the Cable
Manager (packaged separately from the hub) if required. Perform the following
steps:

1 Remove the blank panel by unclipping it.
2 Carefully align one side of the Cable Manager and clip it into position.
3 Bend the Cable Manager outwards slightly and clip the other end into the hub.
4 Press the Cable Manager along its length onto the hub to fasten the remaining

clips.

To remove the Cable Manager gently unclip the side fasteners first from behind
using a screwdriver and then pull it off the hub.

Installing the Depth-Adjusting Plates

If you wish to install the Avaya M770 in a rack which is shallower than the hub itself
you can add two plates on the side panels to reduce the effective rack-mounting
depth.

Avaya M770 User’s Guide 1

Chapter 1 Quick Start

Note: You must install the depth-adjusting plates before installing any modules.

To install the plates perform the following steps:
1 When facing the hub, align each plate so that the narrow flange is toward the

rear of the hub, facing out. See Figure 1.1.

2 From inside the hub, screw on the 4 flat-headed screws to secure the plate to the

side of the hub.

Figure 1.1 Attaching the Depth Adjusting Plate

Decorative Edge Panels

The two plastic side-panels can be removed to allow access to the screw holes.
Simply unclip the panels and replace them. The panels are interchangeable.

Introduction

The Avaya M770 Multifunction Switch is a completely modular, integrated switch
which seamlessly integrates all switching protocols in a single hub.

The combination of Cell Switching and Frame Switching provides switching for
ATM, Ethernet, Fast Ethernet, and Gigabit Ethernet.

Note: The ATM functionality of the Avaya M770 is detailed in the M770 ATM
Switch User’s Guide.

Architecture

The Avaya M770 hub features distributed processing on each of the modules, so
there is no single point of failure. Most of the switching takes place on the module
itself; only when a packet must travel from one module to another does it traverse
the backplane. It is this combination of module and backplane switching that
enables the Avaya M770 to deliver aggregate bandwidth of over 80 Gbps.

The Avaya M770 Multiswitching Backplane

The Avaya M770 architecture enables you to use whichever mix of switching
technologies you require.

The Avaya M770 hub has multiple modular backplanes, allowing connection of
Frame switch, Cell switch, and Avaya M440 Gate Switch modules.

The lower section of the backplane is dedicated to frame switching and supports
two frame switches, called DomainXs. Frame Switch modules can be inserted into
either of the DomainXs - DomainXL in the left half of the hub (slots 1-7), DomainXR
in the right half of the hub (slots 8-14).

The upper backplane supports two switches called DomainGs, currently used for
cell switching. Cell switch modules can be inserted into either of the DomainGs ­DomainGL in the left half of the hub, DomainGR in the right half of the hub.
Although the upper backplane is currently utilized for ATM cell transfer, its bus
architecture is open, and can be easily adapted to support new technologies as they
emerge.

The lower section of the backplane also includes the High Speed bus for Avaya
M440 modules and their agent modules. Since these modules are 6U high, an
adapter bracket is required for their insertion (see Chapter 5).

DomainX Budget Calculation

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 2.1 DRU Budget of DomainX Modules

Module Name DRU Budget

M-SPV/M-SPX 10 DRUs

M12-100T 18 DRUs

M12-100F 18 DRUs

M2-1000 15 DRUs

M-MLS 6 DRUs

Chapter 2 Introduction

M14-10F 6 DRUs

M24-10T 9 DRUs

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/M-SPX you

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

Avaya M770 User’s Guide 5

Chapter 2 Introduction

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

DRU Overload

Warning: Always verify that the DRU calculation never exceeds 100 DRUs.
A DRU overload can be identified by:

• Blinking OPR LED of each module (can also indicate a module fault).

• Via the Avaya M770 CajunView Manager NMS application. Check the DRU report

window (in the Configuration drop-down Menu).

• Using the “Set Show” command in the Zoom view of the Avaya M770 CajunView

Manager.

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 1 M-SPV/M-SPX, two M12-100T and one M12-100F
module.

Avaya M770 Management Architecture

The back of the Avaya M770 hub has two slots which house the main and backup
Avaya M770 Supervisor modules, called M-SPV/M-SPX. The Supervisor module,
together with the CajunView network management system, provides a zoom view
of the Avaya M770 hub and all resident modules, regardless of technology. A
graphical display shows the position of each module in the hub and its status in
real-time. The Supervisor module also handles basic configuration functions such as
enabling and disabling settings. To perform more advanced configuration and
monitoring functions, the Avaya M770 Supervisor launches distributed
management sub-agents, located on the modules themselves. The distributed
management architecture allows no single point of failure for hub management; it is
implemented as follows:

• DomainX Avaya M770 modules are managed by an on-board CPU, which is
responsible for module management. The frame switch modules are managed
as SNMP sub-agents, with the main M-SPV serving as their SNMP agent.

• Avaya M770 ATM modules are managed as sub-agents by a single ATM
module which is designated as the SNMP agent for all other ATM modules in
the hub. Each Avaya M770 ATM module has an on-board agent CPU.

• Modules based on any future technology will also be managed independently,
by a member of that technology family (as with the ATM modules).

• All Avaya M440 modules are managed by NMA-RS or NMA-RE agents.

Chapter 2 Introduction

Note: For proper management of Avaya M440 modules in the Avaya M770 hub, the
NMA-RS/NMA-RE modules should be upgraded to S/W version 8.1.6.

The M-SPV/M-SPX Supervisor Module

This 9U module is essential for the correct functioning of the Avaya M770. The
module is located in the rear of the Avaya M770 (see Figure 3.2). Although the hub
has full functionality with only one agent, it is recommended to install an additional
module as a backup. The agent has the following key functions:

• The M-SPX supports Inter-Domain Switching (IDS) for combining the two
Avaya M770 X-Domains (not available in the M-SPV). Connecting the domains
doubles the available port count in a single switch. The M-SPX module can
operate in two modes with IDS on or IDS off.

• SNMP management

• Frame Switch arbitration

• Monitoring of Avaya M770 sub-systems, including:
— Power supplies
— Fans and temperature
— Informing the user and hub’s front panel LEDs of sub-system status

• Clock generation.

For more detailed information about the M-SPV/M-SPX please refer to the M-SPV
and M-SPX Installation Guides.

Caution: Do not mix M-SPV and M-SPX modules in the same hub.

Communication with the M-SPV/M-SPX

The M-SPX enables the SNMP agent entity of the Meritage 1400 to be accessed by
the Network Management Station (NMS) through its two sideband management
interfaces. Sideband communication is carried out through one of the auto­negotiation 10/100M Ethernet sideband ports on the front panel of the hub, to
which you can connect the NMS. An additional interface for setup purposes is the
RS-232 Console connector on the hub’s front panel, to which a terminal or modem
can be connected.

Communication with Internal Management

The M-SPX has two additional SNMP communication links, used for internal
management communication:

• An Ethernet Management Bus (EMB) to communicate with all DomainX (12U)
modules (agents and sub-agents) in the hub.

• An Ethernet bus which communicates with NMA-R* agents, to support Legacy
hub (6U) modules.

available port count. Set the switch ON or OFF as required.

Caution: When installing two M-SPX modules, the IDS switch must be
set to the same position on both modules.

Sideband Port SB2-ETH

Two RJ-45 Sideband ports, SB1-ETH and SB2-ETH, on the Avaya M770
hub front panel are supported by the M-SPX (see Figure 3.1). The
M-SPV supports only the SB1-ETH port.

Resetting the M-SPV/M-SPX

Each M-SPV/M-SPX can be reset individually via a reset button on the Control
Panel (see page 10) or using the reset button on the M-SPV/M-SPX module itself.
Resetting the M-SPV/M-SPX does not reset the entire hub (for details on resetting
the hub, see page 10).

Chapter 3 Avaya M770 Hub Components

M-SPV/M-SPX Front Panel Port

The RJ-45 Console port on the M-SPV/M-SPX is used for terminal setup.

The M-PS Power Supply Unit

At least one M-PS Power Supply unit is necessary for the operation of the
Avaya M770 but up to three M-PSs can be installed in the hub.

For more detailed information about the Power Supply please refer to the M-PS
Installation Guide.

M-PS Indicator

In addition to the PS status LEDs on the control panel of the Avaya M770 hub, each
M-PS has a LED indicator on its rear panel for viewing its status at a glance during
insertion and replacement of M-PSs.

Table 3.5 M-PS Status LED

LED Name Represents State Function

STATUS Power Status

Power Budget Considerations

The recommended Avaya M770 configuration is two M-PS units, plus a third unit
for redundancy. Such a configuration supports any number of DomainX and Avaya
M440 modules in the hub.

If there is only one M-PS 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 M440 modules,

• 3 or less DomainX modules with 5 or less Avaya M440 modules.

Two M-PS power supplies support any combination of Avaya M440 and DomainX
modules. For redundancy it is recommended to install the third M-PS as well.

1The guidelines take into consideration a maximum power consumption of
60W@48V for each DomainX module and 20W@5V for each Avaya M440 module.
The sub-systems’ power consumption (M-SPV/M-SPX, redundant M-SPV/M-SPX,
fans, backplanes) was also already taken into consideration.

Chapter 4 Replacing Components

Replacing a Supervisor Module (M-SPV/M-SPX)

Caution: The M-SPV/M-SPX is essential to the correct functioning of the Avaya
M770. It is therefore recommended to have two modules installed at all times.
However, you cannot install both an M-SPV and an M-SPX module in the same hub.

Either of the two M-SPV/M-SPX modules can be replaced without powering down
the Avaya M770 hub. If one slot is empty, insert the new module into the empty slot
and wait one minute before removing the module you wish to replace. The new M­SPV/M-SPX automatically inherits the configuration of the main M-SPV/M-SPX
within one minute.

For more detailed information about the M-SPV/M-SPX please refer to the M-SPV
and M-SPX Installation Guides.

Inserting the M-SPV/M-SPX in the Hub

At the back of the Avaya M770 hub there are two slots for two M-SPX modules.

The M-SPX can be installed or removed while power is applied to the enclosure.

1 Insert the M-SPX into an available slot in the back of the hub. Plug in the

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

2 Secure the module by folding the modules handles, and fastening the two

retaining screws. Do not over-tighten the screws.

3 If you intend to install two M-SPX modules into the hub, first insert one of them

and configure it completely as detailed in Chapter 3 of the M-SPX Installation
Guide. Next insert the second M-SPX, and it will auto-configure itself
identically to the first M-SPX (within 5 minutes).

Connecting the Console Terminal

Initial software configuration of the M-SPX is done using a console terminal
connected to the Console connector on the front of the Avaya M770 hub. Refer to the
Appendix for connector pin assignments.

To connect the Avaya M770 to a console terminal:
1 Turn on the VT100 terminal (or PC terminal emulator in VT100 or VT52 mode)

and set its communication parameters to:
Baud rate: 9600 bps
Start bit: 1
Data bits: 8
Stop bit: 1
Parity: None

To remove an M-SPV/M-SPX perform the following steps:
1 Release the two retaining screws, one at the top and one at the bottom of the

module.

2 Unfold the levers and gently slide the module out.

Replacing a Fan

Caution: The fan may rotate for a short while after it is removed from the Avaya
M770.

Note: Although one fan is sufficient to cool the Avaya M770, it is recommended to
use two fans to ensure maximum resiliance.

The fans are hot-swappable and interchangeable. One fan will fit on either the left or
right side: turn the fan upside down if necessary.

To replace a fan perform the following steps (see Figure 4.1):
1 Release the fan’s four screws and gently pull the unit out half way.
2 Wait until the fan stops rotating, then pull it out all the way.

3 Insert the replacement fan, ensuring that it is correctly aligned, and fasten the

four screws.

Replacing a Backplane

The Avaya M770 has two backplanes. The lower backplane serves the X-switch and
Avaya M440 Gate Switch modules, while the upper backplane connects the
Avaya M770 ATM modules. Each backplane is sent with a detailed Installation
Guide. The location of each backplane in the hub is shown in Figure 4.2 below.

Using Avaya M440 Gate Switch 6U Modules

Permissible 6U Modules and their Location

The Avaya M770 supports all switching modules (LSA+, LSE-108, LSE-208, LSE-404,
LSE-404S, LSE-808, LSF-100, LFE-100, LFE-1008, LFE-4004, LFE-4004S, LBT-155,
LHB, LEB-200 and 3LS) but not shared Ethernet modules. All Avaya M440 modules
can be inserted into the hub, using a module adapter (see following section). There
are several considerations to keep in mind when using Avaya M440 modules:

1 The NMA-RS agent module should be inserted into slot 13 and 14 of the hub.
2 The NMA-RE agent module should be inserted into slot 14 of the hub.
3 You can use the LSE-MON module only if you set its internal jumper to Clock

Disable (applicable only to C/S version D and up).

Using the 6U Module Adapter

This section explains how to insert 6U Avaya M440 modules in the Avaya M770 hub
using the optional adapters.

Two types of adapters are available:
1 M-LS1 single-slot 6U module

2 M-LS2 dual-slot 6U module.

Use the type appropriate for the 6U module you are inserting.

Caution: The 6U modules contain components which are sensitive to electrostatic
discharge (ESD). To prevent ESD damage handle the module by its edges and do
not touch the circuit board components unless instructed to do so.
Before handling the module, touch the Avaya M770 chassis to discharge any
electrostatic charge on your body.

In order to use the adapter perform the following steps:
1 Insert the adapter into the Avaya M770 until the adapter is correctly sited, and

tighten the adapter screws.
2 Insert the 6U module gently into the adapter as shown in Figure 5.1.
3 Gently tighten the module’s retaining screws.

To remove an adapter:
1 Release the module’s retaining screws, and pull the module out by its handle.
2 Release the adapter’s screws, and pull the adapter out.
