ACX5000Universal Access Router Overview

TheACX5000UniversalAccessRoutersare JuniperNetworks’ top-of-rack router solutions

for data centers and campus distribution or aggregation environments. The ACX5000

router portfolio consists of high-performance fixed-configuration routers that add higher

port densities, additional scalability, and improved latency to the ACX Series. The

ACX5000 routers are available in twomodels—ACX5048andACX5096. See “ACX5000

Router Models” on page 5.

ACX5000 routers offer a compact 1 Umodel and a 2 Umodel that provide wire-speed

packet performance, very low latency, and a rich set of Layer 2 and Layer 3 features.

These routers have a high-throughput Packet Forwarding Engine, and the performance

of the control plane running on ACX5000 routers is enhanced by the 1.5 Ghz dual-core

Intel CPUwith 8 GB of memory and 32 GB of solid-state drive (SSD) storage.

The ACX5000 routers include both 10-Gigabit Ethernet and 40-Gigabit Ethernet fixed

configurations.

The ACX5000 router consists of:

• ACX5048 Router on page 3

• ACX5096 Router on page 4

ACX5048 Router

As shown in Figure 1 on page 4, the ACX5048 is a 10-Gigabit Ethernet enhanced small

form-factor pluggable (SFP+) top-of-rack router with 48 SFP+ ports and 6 quad SFP+


(QSFP+) ports. Each SFP+ port can operate as a native 10-Gigabit Ethernet port or as a

1-Gigabit Ethernet port when 1-gigabit optics are inserted. EachQSFP+ port (48 through

53) can operate as a 40-Gigabit Ethernet port or be channelized to operate as four

independent 10-Gigabit Ethernet ports (a total of 24 10-Gigabit Ethernet ports). The

6QSFP+ports canbe used as either access ports or uplink ports. TheACX5048provides

full duplex throughput of 1.44 Tbps. The ACX5048 has a 1 U form factor and is shipped

with redundant fans and redundant power supplies. The router can be ordered with

front-to-back airflow (air out or AFO) and with AC or DC power supplies.

ACX5096 Router

As shown in Figure 2 on page 4, the ACX5096 is a is a 10-Gigabit Ethernet enhanced

small form-factor pluggable (SFP+) top-of-rack router with 96 SFP+ ports and 8 quad

SFP+(QSFP+)ports. EachSFP+port canoperateasanative 10-Gbpsport or asa 1-Gbps

port. The QSFP+ ports 96 and 100 can operate at native 40 Gbps speed or can be

channelized to 4 independent 10 Gbps port speeds. The 8 QSFP+ ports can be used as

either access ports or as uplinks. The ACX5096 has a 2U form factor and is shippedwith

redundant fans and redundant power supplies. The router can be ordered with

front-to-back airflow (air out or AFO) and with AC or DC power supplies.

Field-Replaceable Units in an ACX5000 Router

Field-replaceable units (FRUs) are components that you can replace at your site. The

ACX5000 FRUs are hot-insertable and hot-removable: you can remove and replace

themwithout powering off the router or disrupting the routing function.

The following are the ACX5000 FRUs:

• Power supplies

• Fanmodules

Table 4 on page 6 lists the FRUs for the ACX5000 and actions to take before removing

them.

NonePower supplies

NoneFanmodules

CAUTION: Replace a failed power supply with a blank panel or new powersupply within oneminute of removal to prevent chassis overheating. Therouter continues to operate with only one power supply running. Replace afailed fanmodule with a new fanmodule within oneminute of removal toprevent chassis overheating. Do not operate the router withmissing FRUsfor longer than oneminute.

NOTE: If you have a Juniper J-Care service contract, register any addition,change, or upgrade of hardware components athttps://www.juniper.net/customers/csc/management/updateinstallbase.jsp .

Failure to do so can result in significant delays if you need replacement parts.This note does not apply if you replace existing components with the sametype of component.

NOTE: Before removing the optical transceivers, we recommend that youdisable the interface using the set interfaces interface-name disablecommand.See“DisconnectingaFiber-OpticCable fromanACX5000Router”on page 145.

Understanding Hardware Redundancy of an ACX5000 Router Components andFunctionality

The following hardware components provide redundancy on an ACX5000 router:

• Power supplies—The ACX5000 router has one or two power supplies. Each power

supply provides power to all components in the router. If two power supplies are

installed, the two power supplies provide full power redundancy to the device. If one

power supply fails or is removed, the second power supply balances the electrical load

without interruption.



https://www.juniper.net/customers/csc/management/updateinstallbase.jsp

To provide power redundancy to the system both power supplies must be installed.

Connect power source feed A to one power supply and power source feed B to the

second power supply.

CAUTION: Do not connect feed A and feed B to the same power supplyinput terminal.

• Cooling system—The 1 U ACX5048 router has five fanmodules; the 2 U ACX5096

router has three fanmodules. If a fanmodule fails and is unable to keep the ACX5000

router within the desired temperature thresholds, chassis alarms occur and the

ACX5000 router can shut down.

ACX5000 SystemSoftware Overview

ACX5000 routers use the Junos operating system (OS), which provides Layer 2 and

Layer 3 switching, routing, and security services. Junos OS is installed on an ACX5000

router’s 32-gigabyte (GB) internal solid state flash drive. The same Junos OS code base

that runs on an ACX5000 routers also runs on all Juniper Networks QFX and EX Series

switches, and J Series, M Series, MX Series, ACX Series and T Series routers.

For more information about which features are supported on an ACX5000 routers, see

“Protocols and Applications Supported by the ACX Routers” on page 10.

Youmanage the router using the Junos OS command-line interface (CLI), accessible

through the console and out-of-bandmanagement ports on the router.

Port Panel of an ACX5048 Router

The port panel of the ACX5048 supports up to amaximum of 72 logical 10 GbE ports

when operating as a standalone router. Forty-eight physical ports(0 through 47) support

10 Gbps small form-factor pluggable plus (SFP+) transceivers. These ports can be

configured as access ports. See “Interface Specifications for SFP, SFP+, and QSFP+

Transceivers for an ACX5000Router” on page 62 and “Interface Specifications for SFP+

DAC Cables for an ACX5000 Router” on page 77. All 48 of these ports can be used for

SFP+ transceivers or SFP+ direct attach copper (DAC) cables. You can use 1-Gigabit

Ethernet SFP, 10-Gigabit Ethernet SFP+ transceivers and SFP+ direct attach copper

cables in any access port.

The remaining 24 logical ports are available for six 40 GbE ports (48 through 53) that

support up to six quad small-form factor pluggableplus (QSFP+) transceivers orQSFP+.

Each QSFP+ socket can operate either as a single 40 Gbps port or as a set of 4

independent 10 Ggps ports using QSFP+ breakout cables. The 40 GbE ports can be

configured as either access ports or as uplinks. See “Interface Specifications for QSFP+

DAC Breakout Cables for an ACX5000 Router” on page 82.

CAUTION: Donot place a copper transceiver in an access port directly aboveor below another copper transceiver. Internal damage to the access portsand router canoccur.We recommendeitherusing the topport rowexclusively,or bottom port row exclusively, for copper transceivers.

Port Panel of an ACX5096 Router

The port panel of the ACX5096 router consists of 96 small form-factor pluggable plus

(SFP+) and 8 quad small-form factor pluggable plus (QSFP+) ports. Physical ports(0

through 95) support 10 Gbps SFP+ transceivers and normally are configured as access

ports. The eight 40-Gigabit ports (96 through 103) support QSFP+ transceivers and are

normally configuredasuplinks orVirtual Chassis ports (VCPs). Although the 104physical

ports of the ACX5096would map to 128 logical ports using channelization, only 104

logical ports are supported.

Figure 10 on page 21 shows the port panel of a ACX5096 router.

This topic describes:

• Router Ports on page 21

• Channelizing Interfaces on page 22

Router Ports

The ACX5096 ports, (0 through 95) support:

• 1 Gbps SFP transceivers

• 10 Gbps SFP+ transceivers



• 10 Gbps direct attach copper (DAC) cables

Ports 96 through 104 support:

• 40 Gbps QSFP+ transceivers

Additionally ports 96 and 100 support:

• QSFP+ direct attach copper (DAC) cables

• QSFP+ to SFP+ direct attach copper break out (DACBO) cables

• QSFP+ to SFP+ fiber break out cables

See “Interface Specifications for SFP, SFP+, and QSFP+ Transceivers for an ACX5000

Router” on page 62 and “Interface Specifications for SFP+ DAC Cables for an ACX5000

Router” on page 77. All 96 of these ports can be used for SFP+ transceivers or SFP+

direct attach copper (DAC) cables. You can use 1-Gigabit Ethernet SFP+,

10-Gigabit Ethernet SFP+ transceivers and SFP+ direct attach copper cables in any

access port.

CAUTION: Donot place a copper transceiver in an access port directly aboveor below another copper transceiver. Internal damage to the access portsand router canoccur.We recommendeitherusing the topport rowexclusively,or bottom port row exclusively, for copper transceivers.

Channelizing Interfaces

The port panel of an ACX5096 supports up to amaximum of 104 logical 10 GbE ports

that can be distributed over 96 small form-factor pluggable plus (SFP+) and 8 quad

small-formfactorpluggableplus (QSFP+) transceivers .Becauseofan 104port restriction,

only two of the eight QSFP+ can be channelized. Depending on how you set the system

mode for channelization, the behavior of channelization for the QSFP+ changes. The

following systemmodes are available for the ACX5096 router:

• Non-oversubscribed

All 96 SFP+ ports on the router (PIC 0) are supported. In this mode, the eight QSFP+

ports are not supported and cannot be channelized. There is nopacket loss for packets

of any size in this mode.

• Default mode

All 96 SFP+ ports on the router (PIC 0) are supported. QSFP+ ports 96 and 100 can

be channelized. If ports 96 and 100 are channelized, the interfaces on ports 97, 98, 99,

101, 102, and 103 are disabled.
