Chapter 1
Calix E7-2 Product Overview
This chapter introduces the Calix E7-2 Ethernet service access platform and provides a
general overview of the E7-2 small form factor chassis and components.
Topics Covered
This chapter covers the following topics:

Introducing the Calix E7-2
The Calix E7-2 Ethernet service access platform is a compact IP services networking system
that provides high performance Ethernet-based transport, aggregation, and FTTP services
delivery from an environmentally hardened, small form factor chassis.
Calix E7-2 system
The Calix E7-2 delivers a wide array of high performance applications, including 10GE
Ethernet transport, high-density residential triple play services over GPON and point-to-
point Ethernet, Metro Ethernet Forum (MEF) compliant business services, mobile backhaul,
and protected GE aggregation.
Calix E7-2 shelf views
The Calix E7-2 system consists of the 2-slot E7-2 chassis, a removable fan module, and up to
two high capacity line cards in universal card slots.
Calix E7-2 (front)
The Calix E7-2 line cards and fan module install into the front of the E7-2 shelf. When
equipped with line cards, the E7-2 front panel also terminates system line interfaces (fibers).
The E7-2 fan module is equipped with Craft Ethernet and serial ports for management and
features several system status indicators.
Calix E7-2 (rear)

The E7-2 power inputs (A/B), ground, alarm I/O, Craft management, and BITS timing
interfaces are located on the rear of the E7-2 shelf. The E7-2 rear panel also has four RJ-21
copper interface connectors.
Calix E7-2 cards
The Calix E7-2 is equipped with two universal line card slots, supporting a flexible array of
high capacity line cards, including:
Fiber access service line cards: Calix E7-2 fiber cards provide optical ports for front
access termination.
Copper access service line cards: Calix E7-2 copper cards (e.g., VDSL2) terminate on
the E7-2 rear panel.
All E7-2 line cards use pluggable transceiver modules for optical and copper-based interfaces,
including industry standard SFP, SFP+ and XFP modules. Each port on each card has an
LED to indicate an established link and data traffic activity. For detailed information on the
E7-2 line cards, see the Calix E7 User Guide.
An E7 'blank' card (equipped with no electronics) ships with every E7-2 shelf. The blank
card plugs into either of the two universal slots and is used to maintain emissions and
facilitate proper airflow in E7-2 systems with only one line card. Whenever an E7-2 shelf
operates with only one line card, a blank card must be installed in the other slot.

Safety Recommendations and Notices
WARNING! The intra-building port(s) of the equipment or subassembly is
suitable for connection to intra-building or unexposed wiring or cabling only.
The intra-building port(s) of the equipment or subassembly MUST NOT be
metallically connected to interfaces that connect to the Outside Plant (OSP)
or its wiring. These interfaces are designed for use as intra-building
interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE,
Issue 4) and require isolation from the exposed OSP cabling. The addition
of Primary Protectors is not sufficient protection in order to connect these
interfaces metallically to OSP wiring.
WARNING! This product should be protected by a surge protector that
meets the applicable criteria of GR-974-CORE or GR-1361-CORE. Failure
to utilize an appropriate surge protector could result in susceptibility to
lightning surges or create a potential hazard due to power faults.
WARNING! Only qualified technical personnel should perform the
procedures in this document. These procedures involve potentially
hazardous activities that could cause injury to untrained personnel.
DANGER! Risk of high power current surge and electric shock. Read and
understand all power procedures before performing tasks. Take necessary
precautions and use appropriate insulated tools when working with power.
This equipment must be installed, operated, and serviced by qualified
technical personnel only.
DANGER! CLASS 1 LASER PRODUCT. INVISIBLE LASER RADIATION
PRESENT. Fiber optic radiation can cause severe eye damage or
blindness. Do not look into the open end of an optical fiber.
ESD ALERT! Beware of electrostatic discharge. Follow standard ESD
precautions. Always wear a grounded ESD wristband to avoid damaging the
electronic equipment.

Preparations Before You Begin
Complete the following preparations before you begin the installation process.
Site requirements
Before starting the installation, verify that the following conditions are true:
All materials are onsite and inventoried.
An equipment rack and grounding system are available
Minimum clearances are met for each device.
Access to a -48 VDC power source with fuse-protected distribution is available.
The installation site has restricted access.
Cable lengths and wire gauges are adequate for the services provided.
Thermal budget is accounted for and approved.
Assignments for power, transport, services, alarms, timing, and other interfaces have
been defined.
Determining an installation location
For indoor rack-mounted units, keep the following requirements in mind when choosing an
installation location:
As an environmentally hardened system, the Calix E7-2 is suitable for installation in
network telecommunication facilities including outside plant (OSP) locations.
The E7-2 requires one rack unit (1 RU) of mounting space on a standard 19- or 23-inch
(48.26- or 58.42-cm) equipment rack.
The E7-2 fan module is located on the right side of the unit. The system requires
adequate airflow space on the right side (intake) and left side (exhaust) of the unit for
proper cooling. For this reason, EIA or 23-inch (58.42-cm) racks are preferred over 19-
inch (48.26-cm) telco racks.
Note: Calix offers an optional cool air intake and rear heat exhaust system to assure
adequate airflow. Refer to Installing an Intake/Exhaust System (on page 31) for installation
instructions.
Locate the E7-2 near power supply and ground termination locations.
Note: The power and ground cables supplied with the E7-2 installation kit are 12 feet
(3.66 meters) long.
Power, ground, and alarm wiring at the rear of the E7-2 must be properly secured with
strain relief.
Fibers attached to pluggable transceiver modules on the front of the E7-2 unit must be
appropriately dressed and secured with strain relief to avoid exceeding the manufacturer's
bend radius standards.
