P112T Stackable Switch Installation Guide 3

Overview

This Installation Guide consists of three sections

• Description: A general description of the features of the P112T Stackable

Switch.

• Switch Installation: Step-by-step instructions for getting the switch up and

running.

• Diagnostics: Illustration of the front panel with LED indicators and their

meanings.

Description

The P112T Stackable Switch provides wire-speed switching between 24 10BASE-T

ports and can operate in either half or full duplex Ethernet. Up to four switches can

be stacked, and up 32,000 MAC addresses per stack are supported. A redundant

power supply may be used for enhanced fault tolerance.

The units are linked using the P110 Exoplane connectors. These make up a

multi-gigabit, non-blocking backplane. A stack of two or more switches requires a

P110 NMA management agent.

The P112T Stackable Switch has a set of services which ensure zero data loss. An

automatic fairness mechanism ensures that all ports gain fair access to the P110

Exoplane even at very high network utilization. Congestion management ensures

no packet loss by throttling back the traffic from the sending stations should the

buffers become saturated during peak load conditions.

P112T Stackable Switch Installation Guide 5

Installation

The procedure for getting the P112T up and running depends on whether the

switch is to operate standalone or as part of a stack.

First, attach the adhesive rubber legs to the base of the switch. If the switch is to be

rack mounted, do not attach the legs.

Standalone Operation

Getting the P110 switch working is quick and easy:

1. Connect the power cable to the switch,

2. Connect the Ethernet cables to the front panel ports.

To ensure proper ventilation, ensure that the P110 NMA slot is closed.

The switch is now fully operational.

In order to manage the P110 switch using Avaya MSNM (or any other SNMP

based management system), a P110 NMA network management agent is required.

To install the P110 NMA, refer to its Installation Guide.

Stacking Operation

To make the P112T work as part of a stack (and to give SNMP management

capabilities to a single P112T), a P110 NMA with the correct software version is

required. See the P112T Stackable Switch Release Notes for the required version.

To check what software version you have, see the agent configuration window in

View, or see the setup main menu of the P110 NMA.

1. Before adding a switch to the P110 stack, turn off the main power to the stack,

by individually switching off each switch

2. Place the P110 NMA in the top switch of the stack

3. If the P110 NMA contains the latest software version, go to step 4.

If the P110 NMA does not contain the latest agent software, you should

perform a software download of the latest version.

The latest software is in always shipped with the P110 NMA and is available

on the Avaya Support site. See the P110 NMA Release Notes document for

details.

Download is performed via TFTP using a Terminal console or via the Software

Update Manager. Details can be found in the P110 NMA installation Guide.

Chapter 2 Hub Installation

 Before you download the new P110 NMA software, please note that when

upgrading from P110 NMA version 8.0 or below to 8.1 or higher, all port

configuration parameter settings will be lost. The following parameters will be

set back to the factory defaults:

• In the P114T the Port Speed (10/100 Mbps) parameter will be set to

100 Mbps.

• The Port Mode (Half/Full Duplex) parameter, will be set to Half Duplex.

• Redundancy in the P113F will be set to OFF.

• The Auto Sense (Auto-negotiation) process, where available, will be set to

Disabled.

• All ports will lose their VLAN assignment and will be reassigned to

Generic VLAN.

• The Administration Status of all P110 switches will be Enabled. In order to

avoid any possible loops, any port that you disabled using the

management software must be physically disconnected before software

download. Once you have downloaded the new software, set the port to

disabled again and then reconnect the cable.

4. Place the P112T in the stack. The P110 NMA must be in the top switch of the

stack.

 To ensure proper ventilation, ensure that all empty P110 NMA slots in the

stack are closed.

5. Connect P110 switches using P110 Exoplane cables, as shown in Figure 1.

A switch connects to its upper neighbor through two Exoplane cables, and to

its lower neighbor through another two Exoplane cables.

 Make sure that the P110 Exoplane cables are correctly seated by gently

exerting pressure on the back of the connector.

Chapter 2 Hub Installation

Cabling Requirements:

• For correct operation, the P110 Exoplane must be fully connected, with all units powered

up. In case units are stacked, the P110 NMA must be installed and connected to the P110

Exoplane.

Failure to observe this requirement will cause the units to block all traffic on attached

stations and segments.

• When using the P114T or P114F in the stack, make sure all switches in the stack are

connected using P110 Exoplane cables with white connectors and marked C/S:B

(part number 108362203). Extra cables can be ordered from your local Avaya

representative.

Figure 1 Rear view of a P110 switch stack, showing how the switches are linked via

the P110 Exoplane cables. A P110 NMA resides in the uppermost switch.

6. Two terminators are supplied with the P110 NMA. Insert the two terminators

into the lowest two connectors at the bottom of the stack, as shown in Figure 1.

7. Turn on the mains power to the stack, by individually switching on each

switch.

8. Connect the fiber-optic cables to the front panel ports.

 If the P110 NMA in the stack contains the correct software version (as specified

in the P112T Stackable Switch Release Note) or higher, the stack is now fully

operational.

 When a new version of the P110 NMA software becomes available, you should

perform software download to benefit from the extra capabilities provided. See

the P110 NMA Installation Guide for details.

Chapter 2 Hub Installation

Rack Mounting

P110 switches slot into a standard 19 inch rack.

Remove the rubber legs from the base of any switch that is to be rack mounted.

Place the switches in the rack, and then connect the P110 Exoplane, as follows:

1. Snap open the ends of the front panel to reveal the fixing holes.

2. Slot the switch into the rack. Insert the switches into the rack so that the

switches in a logical stack lie directly on top of each other. Ensure that the P110

screw holes are aligned with the rack hole positions exactly as shown in Figure

3. Stacking them in this way will allow the switches to be easily connected

using the Exoplane cables.

3. Secure the switch in the rack using the screws. Use one screw on each side. Do

not overtighten the screws to avoid damaging the plastic.

4. Connect the Exoplane cables, as described above, and as illustrated in Figure 1.

5. Snap closed the hinged ends of the front panel.
