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.
