Preface
This Preface provides an overview of this guide, describes guide conventions, and lists
other publications that may be useful.
Introduction
This guide provides the required information to in stall the WM-4T1i, WM-4E1i, and
WM-1T3i WAN modules in an Alpine 3800 series switch from Extreme Networks and
perform the initial module conf iguration tasks.
This guide is intended for use by network administrators who are responsible for
installing and setting up n etwork equipment. It assumes a ba sic working knowledge of:
• Local area networks (LANs).
• Ethern et conc epts.
• Ethernet switching and bridging concepts.
• Routing concepts .
• Internet Protocol (IP) co ncepts.
• Routing Information Protocol (RIP) and Open Shortest Path First (OSPF).
• Simple Network Managemen t Protocol (SNMP).
If the information i n the release notes shipp ed with your module diffe rs from the
information in this guide, follow the release no tes.

specific module name is used. E xplanations about feat ures and operations that are the
same for both of the WAN modules simply refer to the product as the “module.”

Installing the WAN Module
This chapter covers the followin g topics:
• Installing the WAN Module on page 1-2
• Ports and Connectors on pa ge 1-3
• Module LEDs on page 1-4
• Installing the WAN Module Software on page 1-6
Overview
The Extreme Networks WAN m odules include four-port T1 or E1 modules that can be
configured to use Multilink PPP t o aggregate Ethernet or IP routed traffic across
multiple T1/E1 physical l inks. The modules also have two general purpose 10/100
Mbps Ethernet ports. WM-4T1i is the designatio n of the T1 version, and WM-4E1i is th e
designation of the E1 version. Also included among the WAN modules is a one-port T3
module, designated WM-1T3i, that uses PPP for its traffic.
The modules also have eight internal loopback po rts. The Alpine 3800 switch m odules
have hardware queues associated with the output of each port for QoS (rate shaping
and priority queueing). To implement ingress QoS, you needed to use the hardware
queues associated with a second port as a loopback port for ingress QoS.

Installing the WAN Module
Installing the WAN Module
All Alpine ™ 3800 series switch module cards (SMMi modules and I/O modules) are
hot-swappable. You do not need to power off the system to remove or insert a module
card.
Caution: Servic e to Alpine modules sh ould be performed by tr ained service
personnel only. Before installing or removing any co mponents of the syst em, or
before carrying out any maintenance proce dures, read the safety inf ormation
provided in Appendix A of the Alpine Hardware Installation Guide.
Warning: You must install blank panel s in empty slots to ens ure adequa te system
cooling.
To remove and replace a module card, follow these steps:
1 Prior to removing/installing a module card into the Alpine 3804 or Alpine 380 8
chassis, put on the ESD wrist strap that is provided with the chassis, and connect the
metal end to the ground receptacle located on the top-right corner of the Alpine
front panel.
2 Loosen the module card by unscrewing the screws usin g a #2 Phillips-head
screwdriver.
3 Rotate the ejector/injector handles t o disengage the module card from the backplane.
Note: Blank pan els do not have ejector/ injector handles, be cause they do not
engage the backpl ane. They are secured e ntirely by the retain ing screws. In
addition, the retaini ng screws are not cap tive.
4 Slide the module card out of the chassis.
5 Slide the new module card into the appropriate slot of the chassis (SMMi modules
into the orange slot, I/O m odules into Slots 1 through 4 o n the Alpine 3804, or Slots
1 through 8 on the Alpine 3808), until i t is fully seated in the backplan e.
Caution: Ensure t hat the sheet metal of the m odule, and not the PCB bo ard,
engages the ca rd cage runners.
As the module begins to seat in th e chassis, the ejector/ injector handles will begin to
close.
6 To secure the module in the chassis, clos e the ejector/injector han dles by pushing
them toward the center of the module card, and tighten the screws using a #2
Phillips-head screwdriver.
1-2 WAN Module Installation and U ser Guide
Note: Tighten the s crews before insertin g additional modu les. If you insert
additional modul es before tightening the screws, you might unseat modules
that you have not se cured.
Caution: You can only install I/O modules in the slots l abeled Slot 1 throug h
Slot 4 o n the Alpine 3804, or Slot 1 through Slot 8 on the Alpin e 3808. Forceful
insertion can dama ge the I/O module and the co nnector pins on the b ackplane.

Figure 1-1: WM-4T1i Module
The WM-4T1i module has four T1 ports and two general purpose 10/100 Ethernet
ports. The WM-4T1i also has eigh t internal loopback ports. Intern al loopback ports
allow you to configure bi-directional rate-limiting without tying up any of the externa l
ports for ingress rate shaping. Internal loopback ports are marked with the notatio n
“iL” when displayed on the command line or with ExtremeWare Vista Web access.
The WM-4E1i module has fou r E1 ports in place of the T1 po rts found in the WM-4T1i
module. It is identical in all o ther respects.
The WM-1T3i module is shown in Figure 1-2.

The WM-1T3i module has one T3 port, consistin g of a two BNC connectors, one fo r the
transmit path and one for the receive path. The module also has two general purpo se
10/100 Ethernet ports. L ike the other WAN modules, the WM-1T3i also has eight
internal loopback ports.
Module LEDs
The T1/E1 module LEDs are shown in Figure 1-3. The WM-1T3i module LEDs are
similar, but there is only one WAN port LED and the Ethernet port LEDs are numbered
2 and 3.

WAN Module Installation and User Gu ide 1-5
Installing the WAN Module
Installing the WAN Module Software
Once the WAN module is installed in the chas sis, you might need to update the i mage
file on the module. See the release notes for your version of ExtremeWare for details.
(You might also need to update the image on the SMMi to o ne that will support the
module. See the ExtremeWare Software User Guide for more information on updating th e
SMMi image.)
The image file contains the executable code that runs on the module. As new versions
of the image are released, you should upgrade the s oftware running on your module.
The image installed on the SMMi and the image installed on the module must be
compatible. New SMMi images and module images are released together, so if you
upgrade both at the same time, y ou will be certain to have compat ible images. If this is
not feasible, see the Extreme Networks customer support website for compatibility
information.
The image is downloaded from either a Trivial File Tra nsfer Protocol (TFTP) server on
the network or from a PC connected to the serial port us ing the XMODEM protocol.
Downloading a new i mage involves the followin g steps:
• Load the new image onto a TFTP server on your network (if you will be us ing
TFTP).
• Load a new image on to a PC (if you will be using XMODEM).
• Download the new image to the module using the command
download image slot <slot> [<ipaddress> | <hostname>] <filename>
{primary | secondary}
where the following is true:
slot — Is the slot in which the module is installed.
ipaddress — Is the IP address of the TFTP server.
hostname — Is the hostname of the TFTP server. (You must enable DNS to use this
option. See the ExtremeWare Software User Guide for more information.)
filename — Is the filename of the new image.
primary — Indicates the primary image.
secondary — Indicates the secondary image.
