Routers
E4G-200 Cell Site Routers
E4G-400 Cell Site Aggregation Router
Pluggable Interfaces for E4G Series Routers
Stacking Options for E4G Series Routers
The Extreme Networks E4G router family consists of the E4G-200 cell site routers (models E4G-200
and E4G-200-12x) 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.
Note
Unless otherwise noted, the term E4G-200 refers in this document to both models in the
E4G-200 series: the E4G-200 and the E4G-200-12x.
The E4G-200 cell site router collects trac from cell site towers for hando to the mobile backhaul
network. The E4G-200 router connects to the E4G-400 cell site aggregation router, which aggregates
T1, E1, and Ethernet trac for hando to the mobile core.
E4G Routers Hardware Installation Guide 9

Figure 1: Mobile Backhaul Architecture
E4G-200 Cell Site Routers
The Extreme Networks E4G-200 routers provide 12 resilient synchronous Gigabit Ethernet ports and 16
T1/E1 ports in a compact (1RU or 1.75 inches high) unit.
Note
Unless otherwise noted, the term E4G-200 refers in this document to both models in the
E4G-200 series: the E4G-200 and the E4G-200-12x.
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 trac from
2G, 3G, and 4G radio towers for hando 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.
Features:
•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 clock module
Extreme Networks E4G Series Routers

E4G-200 Clock (CLK) Module
An optional clock module for the E4G-200 router provides timing. Timing is based on either:
•ITU-T Synchronous Ethernet (SyncE) protocol
•Precision Time Protocol based on the IEEE specification 1588v2
The clock module has four mini-BNC connectors providing Sync In/Sync Out timing interfaces and an
RJ-45 connector that provides an RS-422 BITS-IN interface. Clock modules can be installed or removed
without powering down the router, although a system reboot is required to initialize the module.

E4G-400 Cell Site Aggregation Router
The E4G-400 cell site aggregation router is a compact unit (1RU or 1.75 inches high) that enables
networks to aggregate multiple Ethernet links from various cell sites and route the trac 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.
Extreme Networks E4G Series Routers
E4G Routers Hardware Installation Guide 14

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 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

E4G-400 Combination Ports
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 router 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 User Guide.
