CHAPTER
This chapter describes the Extreme Networks E4G series routers and includes the following sections:
● Overview on page 13
● E4G-200 Cell Site Router on page 14
● E4G-400 Cell Site Aggregation Router on page 18
● Pluggable Interfaces for E4G Series Routers on page 25
Overview
The Extreme Networks E4G router family consists of the E4G-200 cell site router and the E4G-400 cell
site aggregation router. These routers provide high-bandwidth capacity, highly accurate and flexible
timing, and Operations Administration and Maintenance (OAM) capabilities that support service level
agreement (SLA) metrics. They support time-division multiplexing pseudowire end-to-end emulation
(TDM PWE3). PWE allows the simultaneous support of multiple generations of services (2G, 3G and
4G) over the same Ethernet backhaul network without having to remove legacy T1/E1 equipment and
incur associated costs.
The E4G-200 Cell Site Router collects traffic from cell site towers for handoff to the mobile backhaul
network. The E4G-200 router connects to the E4G-400 Cell Site Aggregation Router, which aggregates
T1, E1. and Ethernet traffic for handoff to the mobile core (see Figure 1).

E4G-200 Cell Site Router
The Extreme Networks E4G-200 router provides 12 resilient synchronous Gigabit Ethernet ports and 16
T1/E1 ports in a compact 1RU unit. The Ethernet ports support both IEEE 1588v2 and Synchronous
Ethernet (SyncE) timing, and the T1/E1 ports support time division multiplexing (TDM) timing. The
router provides high-performance pseudowire capability, supporting both CESoPSN (channelized) and
SAToP (unframed and unchannelized) TDM services. Deployed at the cell site, the E4G-200 cell site
router collects traffic from 2G, 3G, and 4G radio towers for handoff to the mobile backhaul over fiber
or microwave.
The E4G-200 extended temperature range of -40°C to +65°C allows service providers to deploy the
E4G-200 router at sites without climate control.
The E4G-200 cell site router front panel (Figure 2) has the following features:
● Alarms port implemented as a DB-15 connector.
For details about the connector, see “E4G-200 Connector Pinouts” on page 113.
● Management and console ports
● Eight 10/100/1000BASE-T (RJ-45) dedicated ports
● Four 100/1000BASE-X (SFP) ports
These ports require Extreme Networks optical modules that are designed for use within the
temperature range of the router.
● Slot for hot-swappable clock module
● Slot for hot-swappable T1/E1 module with 16 ports

The alarms interface is implemented as a DB-15 female connector. This interface relays alarms to an
external device (output alarms) and monitors alarms from an external device (input alarms). The alarms
are controlled from the ExtremeXOS software.
The alarms interface provides two input alarms and eleven output alarms. Input alarms can be
configured to monitor alarms from an external source and raise a trap or flag, or to be an input source
to clear Minor or Major alarms. The output alarms can be connected to an external visual or an audible
interface. The output alarms can be either persistent or non-persistent. For information about
configuring alarms, refer to the ExtremeXOS Concepts Guide.
For details about the connector, see “E4G-200 Connector Pinouts” on page 113.
The E4G-200 router has an integrated DC power supply with dual feeds on the front panel. Power
feed A can be connected to one power source and power feed B can be connected to a different power
source to provide protection should either source of power fail. The power supply is not
field-replaceable.
The back panel of the E4G-200 router provides an alternate attachment point for the grounding lug.
Status LEDs on the E4G-200 router are described in Ta bl e 3 on page 17.

E4G-400 Cell Site Aggregation Router
The E4G-400 cell site aggregation router is a 1RU unit that allows networks to aggregate multiple
Ethernet links from various cell sites and route the traffic to the mobile core. The E4G-400 router
provides 28 Gigabit Ethernet ports and port options for up to six 10-Gigabit Ethernet ports, as well as a
16-port T1/E1 module with pseudowire capability. The T1/E1 module is used where 2G and 3G radios
are co-located at the aggregation site, and eliminates the need for separate cell site routers.
The Gigabit and 10-Gigabit Ethernet ports on the E4G-400 router support Synchronous Ethernet (SyncE)
and IEEE 1588v2 timing. Integrated timing connectors on the front panel provide timing based on either
the ITU-T Synchronous Ethernet (SyncE) protocol or the Precision Time Protocol based on IEEE
specification 1588v2. Four mini-BNC connectors providing Sync In/Sync Out timing interfaces and an
RJ-422 connector provides a BITS-IN interface.
The E4G-400 router has 4 shared ports. For each pair of shared ports, either the 10/100/1000BASE-T
port (RJ45) or 100/1000BASE-X (SFP) port can be used as needed.
The E4G-400 router supports stacking using ports on installed port option cards at the back of the unit.
Up to eight units can be connected into a single management entity that has up to 192 Gigabit Ethernet
ports and up to 32 10-Gigabit Ethernet ports.
At the back of the unit are two bays for either AC or DC power supplies. One 300 W AC or DC power
supply is included with the base unit. A redundant power supply must be ordered separately. You can
mix any combination of 300 W AC and DC power supplies based on the need at the particular site. For
example, you can have a DC main power feed and an AC input backup from an uninterruptible power
supply (UPS).
The front panel of the E4G-400 router (Figure 5) has the following features:
● Twenty 10/100/1000BASE-T (RJ-45) dedicated ports
● Four 100/1000BASE-X (SFP) or 10/100/1000BASE-T (RJ-45) shared ports
● Four 100/1000BASE-X (SFP) dedicated ports
● Timing interfaces
● BITS-IN interface

Chapter 1: About the E4G Series Routers
Combination Ports on the E4G-400 Router
The E4G-400 Cell Site Aggregation Router provides four uplink ports implemented as combination
ports that pair a copper port using RJ-45 connectors with an optical port using LC connectors. The
copper port operates as an autonegotiating 10/100/1000BASE-T port. The optical port allows Gigabit
Ethernet uplink connections through Extreme Networks small form factor pluggable (SFP) interface
modules.
The E4G-400 router supports automatic failover from an active fiber port to a copper backup or from an
active copper port to a fiber port. If one of the uplink connections fails, the uplink connection
automatically fails over to the second connection. To set up a redundant link on a combination port,
connect the active 1000BASE-T and fiber links to both the RJ-45 and SFP interfaces of that port.
Gigabit Ethernet uplink redundancy on the E4G-400 router follows these rules:
● With both the SFP and 1000BASE-T interfaces connected on a combination port, only one interface
can be activated. The other is inactive.
● If only one interface is connected, the switch activates the connected interface.
● The router determines whether the port uses the fiber or copper connection based on the order in
which the connectors are inserted into the router. When the router senses that an SFP and a copper
connector are inserted, the router enables the uplink redundancy feature. For example, if you first
connect copper ports 21 and 22, and then insert SFPs into optical ports 21 and 22, the router assigns
the copper ports as active ports and the fiber ports as redundant ports.
Hardware identifies when a link is lost and responds by swapping the primary and redundant ports to
maintain stability. After a failover occurs, the router keeps the current port assignment until another
failure occurs or a user changes the assignment using the CLI. For more information about configuring
automatic failover on combination ports, see the ExtremeXOS Concepts Guide.

Chapter 2: Site Preparation
Planning Your Site
To install your equipment successfully, you should plan the site carefully. The site planning process has
three major parts:
● Meeting site requirements
The physical installation site must meet the following requirements for a safe and successful
installation:
- Building and electrical code requirements
- Environmental, safety, and thermal requirements for the equipment you plan to install
- Equipment rack requirements
● Evaluating and meeting cable requirements
After examining your physical site and verifying that all environment requirements are met, evaluate
and compare your existing cable plant with the requirements of the Extreme Networks equipment to
determine if you need to install new cables.
● Meeting power requirements
To run your equipment safely, you must meet the specific power requirements for each router and
external power supply unit installed in the system. For power specifications of the router and power
supplies, see the specific router models listed in Appendix B.
Meeting Site Requirements
This section describes requirements to consider when preparing your installation site, and includes the
following topics:
● Operating Environment Requirements (next section)
● Rack and Cabinet Specifications and Recommendations on page 33
● Outdoor Installation Sites on page 35
Operating Environment Requirements
Verify that your site meets all environmental and safety requirements.
Virtually all areas of the United States are regulated by building codes and standards. During the early
planning stages of installing or modifying your network, it is important that you develop a thorough
understanding of the regulations that pertain to your location and industry.
Building and Electrical Codes
Building and electrical codes vary depending on your location. Comply with all code specifications
when planning your site and installing cable. This section lists resources for obtaining additional
information.
For information about major building codes, consult the following organization:
International Code Council (ICC), 5203 Leesburg Pike; Falls Church, Virginia 22041 USA.
