The ACX Universal Access Router is principally designed for high-density access and
pre-aggregation and is environmentally hardened. The router can be used as a cell site
router or pre-aggregation device for mobile backhaul and a CPE for business or residential
access.
ACX4000 Quick Start Description
The ACX Series routers support TDM, Gigabit Ethernet, and 10-Gigabit Ethernet interfaces.
The chassis has eight built-in Gigabit Ethernet combination copper or fiber interfaces
with PoE+ (65 W) support on two ports, two Gigabit Ethernet SFP ports, and two
10-Gigabit Ethernet SFP+ ports. The router also has two slots for modular interface cards
(MICs). For a list of the supported MICs, see the ACX4000 Universal Access Router MICGuide.
The ACX Series router is a single-board router with a built-in Routing Engine and one
Packet Forwarding Engine that has two Flexible PIC Concentrators (shown in the CLI as
FPC 0 and FPC 1). Because there is no switching fabric, the single Packet Forwarding
Engine takes care of packet forwarding:
•
Routing Engine—Provides Layer 3 routing services and network management.
•
Packet Forwarding Engine—Performs Layer 2 and Layer 3 packet switching, route
lookups, and packet forwarding.
The ACX Series router is powered by Junos OS, supporting extensive L2 and L3 features,
IP/MPLS with traffic engineering, rich network management, fault management, service
monitoring and Operation, Administration, and Maintenance (OAM) capabilities, and an
open software development kit (SDK) system that allows providers to customize and
integrate operations with their own management systems. For a list of related Junos OS
documentation, see http://www.juniper.net/techpubs/software/junos/.
As part of the mobile backhaul, the ACX Series router at the cell site and the MX Series
router at the aggregation layer provide comprehensive end-to-end Ethernet, MPLS, and
OAM features with the one Junos OS running on both platforms.
The compact routersare 2.5 rack units (U; that is, 4.375in., or 11.11 cm) tall. Several routers
can be stacked in a single floor-to-ceiling rack for increased port density per unit of floor
space.
The chassis is a rigid sheet metal structure that houses all the other router components.
The chassis measures 4.375 in. (11.11 cm) high, 9.5 in. (24.13 cm) deep, and 17.5 in. (44.5
cm) wide. The outer edges of the mounting brackets extend the width to 19 in. (48 cm)
(from the front-mounting brackets to the rear of the chassis). The chassis installs in
standard 300-mm deep (or larger) enclosed cabinets, 19-in. equipment racks, or telco
open-frame racks.

Step 1: Prepare the Site for ACX4000 Router Installation
Step 1: Prepare the Site for ACX4000 Router Installation
Prepare your site for ACX4000 installation by observing the following guidelines:
•
You can install the router in a four-post rack or cabinet or an open-frame rack.
•
The rack rails must be spaced widely enough to accommodate the chassis's external
dimensions: 4.375 in. (11.11 cm) high, 9.4 in. (24 cm) deep, and 17.5 in. (44 cm) wide.
The outer edges of the mounting brackets extend the width to 19.2 in. (48.7 cm).
•
One person must be available to lift the router while another secures the router to the
rack.
•
The rack must be strong enough to support the weight of the fully configured router,
up to 22.48 lb (10.2 kg).
•
For service personnel to remove and install hardware components, allow at least
2.16 in. (5.5 cm) in front of the router.
•
The rack or cabinet must have an adequate supply of cooling air.
•
Ensure that the cabinet allows the chassis hot exhaust air to exit from the cabinet
without recirculating into the router.
•
When installing the router in a cabinet, ensure that the bottom of the cabinet is closed
and there is no opening.
•
The router must be installed into a rack that is secured to the building structure.
•
Mount the router at the bottom of the rack if it is the only unit in the rack.
•
When mounting the router in a partially filled rack, load the rack from the bottom to
the top with the heaviest component at the bottom of the rack.
•
Install the router only in restricted areas, such as dedicated equipment rooms and
equipment closets, in accordance with Articles 110-16, 110-17,and 110-18 of the National
Electrical Code, ANSI/NFPA 70.
