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 them without powering o the router or

disrupng the roung funcon.

The following are the ACX5000 FRUs:

• Power supplies

5

• Fan modules

Table 2 on page 6 lists the FRUs for the ACX5000 and acons to take before removing them.

Table 2: FRUs in ACX5000 Routers and Acon Required Before Removing Them

FRUs Required Acon

Power supplies None

Fan modules None

CAUTION: Replace a failed power supply with a blank panel or new power supply

within one minute of removal to prevent chassis overheang. The router connues to

operate with only one power supply running. Replace a failed fan module with a new

fan module within one minute of removal to prevent chassis overheang. Do not

operate the router with missing FRUs for longer than one minute.

NOTE: If you have a Juniper J-Care service contract, register any addion, change, or upgrade of

hardware components at hps://www.juniper.net/customers/csc/management/

updateinstallbase.jsp . Failure to do so can result in signicant delays if you need replacement

parts. This note does not apply if you replace exisng components with the same type of

component.

NOTE: Before removing the opcal transceivers, we recommend that you disable the interface

using the set interfaces

interface-name

disable command. See "Disconnecng a Fiber-Opc

Cable from an ACX5000 Router" on page 137.

Understanding Hardware Redundancy of an ACX5000 Router

Components and Funconality

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 interrupon.

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 supply input

terminal.

• Cooling system—The 1 U ACX5048 router has ve fan modules; the 2 U ACX5096 router has three

fan modules. If a fan module fails and is unable to keep the ACX5000 router within the desired

temperature thresholds, chassis alarms occur and the ACX5000 router can shut down.

Protocols and Applicaons Supported by ACX Series Routers

Table 5 on page 12 contains the rst Junos OS Release support for protocols and applicaons on ACX

Series routers. A dash indicates that the protocol or applicaon is not supported.

NOTE:

•The [edit logical-systems

logical-system-name

] hierarchy level is not supported on ACX Series

routers.

11

• The ACX Series routers does not support per-family maximum transmission unit (MTU)

conguraon. The MTU applied to family inet gets applied to other families as well, even

though it can be congured though CLI and visible in show interface extensive output. The only

way to use higher MTU for a family is to manipulate the MTU, apply at interface or family inet

levels, and let it calculate for each family automacally. MTU values are not limited to 1500

but can range between 256 to 9216.
