P116T Stackable Switch Installation Guide 3
Chapter 1
Overview
This guide is divided into two sections:
• Overview: A general description of the features of the P116T Stackable Switch.
• Installation: Instructions for getting the P116T Stackable Switch and P110
Switching System up and running.
Description
The P116T Stackable Switch is part of the P110 Switching System family of
workgroup switches. The P110 family is composed of high-performance
workgroup switches which may be used singly or stacked in any combination to
make up a multi-protocol, non-blocking, scalable switch.
The P116T is a workgroup switch with 16 autosensing Ethernet/Fast Ethernet
(10/100BASE-T) ports. The 10 Mbps ports are ideal for workgroup connectivity,
while the 100 Mbps ports can be used for server connections, high performance
workstations, or to link to another P116T or P113T unit.
The P116T can operate standalone or as part of a stack. A stack requires a
P110 NMA to link the switches. The units are physically linked using the P110
Exoplane, which makes up a multi-gigabit, non-blocking backplane. Any
combination of two, three or four P110 switches can be stacked, and up 32,000
MAC addresses per stack are supported. Only three P116T hubs can be connected
on a stack, and a fourth switch can be connected to the stack only if it is a different
P110 model.
All ports can run at full or half duplex Ethernet. With a P110 NMA installed, the
ports can perform standards-based auto-negotiation. Port software-redundancy
can be defined via CajunView or MSNM SNMP-based management system. A
redundant power supply may be used for enhanced fault tolerance.
The P116T ports can use Avaya’s flow control mechanism to eliminate packet loss.
An automatic fairness mechanism ensures that all ports gain fair access to the P110
Exoplane even at very high network utilization. Congestion management works
half duplex ports, and ensures no packet loss should the buffers become saturated
during peak load conditions.
P110 switches are fully manageable, using CajunView or MSNM, and may be
monitored using the SMON Manager Switch Monitoring Application.

Installation
Setting the DIP switches
First, set the DIP switches. The position of the switches depends on the P110
application. The drawing below shows the default positions of the DIP switches on
the rear panel of the P110 hub.
Figure 1 The P116T Stackable Switch Rear Panel Showing The DIP
Switches In their Default Positions
The DIP switches control the sixteen 100 Mbps ports. The ports can also be
controlled by CajunView, MSNM, or any SNMP network management application
via the P110 NMA. A detailed explanation of the DIP Switches follows.
• 1-16: Selects whether the port will operate at 10 Mbps or 100 Mbps.
• USE SW (Use Switches): Selects whether the 10/100 mode will be controlled
from the management station or by the DIP switches.
When set to ON, 10/100 Mbps switch settings are determined by the DIP
switches only. Settings can be monitored, but not changed, by the management
station.
When set to OFF, the DIP switch settings are ignored and the 10/100 Mbps
port functionality is controlled from the management station via the
P110 NMA, or via auto-negotiation.
Set to ON when you don’t have SNMP management, or when you want to
ensure that the settings will not be changed.
 In stand-alone mode (that is, with no P110 NMA installed), the 10/100 mode is
always controlled via DIP switches 1-16.
 Always reset the hub after changing switch configurations.

P116T Stackable Switch Installation Guide 7
Installing the P116T Stackable Switch
The procedure for getting the P116T Stackable Switch up and running depends on
whether the hub is to operate standalone or as part of a stack.
First, attach the adhesive rubber feet to the base of the P110 switch. If the switch is
to be rack mounted, do not attach the feet.
Standalone Operation - Plug ‘n’ Play
Getting the P110 hub working is quick and easy:
1. Connect the power cable to the hub,
2. Connect the cables to the front panel ports,
To ensure proper ventilation, ensure that the P110 NMA slot is closed.
The hub is now fully operational. By default, all ports will operate as 100 Mbps
ports, in half-duplex mode. Port settings can be changed using the DIP switches
Stacking Operation
To make the P116T work as part of a stack (and to give SNMP management
capabilities to a single P116T), a P110 NMA with the correct software version (8.4
or higher) is required. See the Release Notes for the required version.
You should make sure the P110 NMA has the latest agent software. To check what
software version you have, see the agent configuration window in CajunView or
MSNM, or see the setup main menu of the P110 NMA.
2. Before adding a switch to the P110 stack, turn off the main power to the stack,
by individually switching off each hub
3. Place the P110 NMA in the top hub of the stack
4. If the P110 NMA contains the latest software version, go to step 4.
5. 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.
Download is performed via FTP using a Terminal console or via CajunView or
MSNM – details can be found in the P110 NMA installation Guide.
 When a P110 unit is added to, removed from or swapped in a stack, all
Ethernet port settings (Administration Status, Port Mode, port speed and
VLANs) will return to their default values. However, the Administration and
Port Mode status of the P113F 100 Mbps ports will retain their values.

Chapter 2 Installation
8P116T Stackable Switch Installation Guide
 Configuration parameters will be set back to factory defaults if they were set
using the management station. The factory default parameters are described in
the P110 NMA 8.4 Release Note.
4. Place the P116T and any other additional P110 hubs in the stack.
Caution: You cannot connect more than three P116T hubs on a stack. If you wish
to connect four hubs in a stack, the fourth hub must be a different P110 model.
5. Connect P110 hubs using the P110 Exoplane cables, as shown in Figure 2.
A hub connects to its upper neighbor through two P110 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.
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.

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 2.
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 P116T 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.

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 2.
5. Snap closed the hinged ends of the front panel.
