ACX5448, ACX5448-D, and ACX5448-M Chassis

 

The front panel on the ACX5400 chassis contains LEDs for the router components, a reset button, management and console ports, and network ports. On the front panel, you can view status and troubleshooting information at a glance.

The rear panel of the router has slots for the power supply modules (PSMs) and fan modules. The power and fan modules are installed from the rear of the router.

Management Panel of ACX5400 Routers

The management panel of ACX5400 routers is found on the front of the router.

Port Panel of an ACX5448 Router

The port panel of the ACX5448 router has the following port configurations:

  • Forty-eight 10-Gigabit or 1-Gigabit Ethernet ports (ports 0 through 47) that operate at 10-Gbps speed with SFP+ transceivers or at 1-Gbps speed when you use SFP optics.

  • Four 100-Gigabit Ethernet ports (ports 48 through 51) that support quad small form-factor pluggable 28 (QSFP28) transceivers. You can channelize these ports into four 25-Gbps interfaces using breakout cables (and channelization configuration). These ports also support 40-Gbps speed, when you use QSFP+ optics. You can channelize these 40-Gbps ports into four 10-Gbps interfaces using breakout cables (and channelization configuration).

Port Panel of an ACX5448-D Router

The port panel of the ACX5448-D router has the following port configurations:

  • Thirty-six 10-Gigabit or 1-Gigabit Ethernet ports (0 through 35, mapped to CLI PIC 0) that operate at 10-Gbps speed with SFP+ transceivers or at 1-Gbps speed when you use SFP optics.

  • Two 100-Gigabit Ethernet ports (36 and 37, mapped to CLI PIC 1) that support QSFP28 transceivers. You can channelize these ports into four 25-Gbps interfaces using breakout cables (and channelization configuration). These ports also support 40-Gbps speed, when you use QSFP+ optics. You can channelize these 40-Gbps ports into four 10-Gbps interfaces using breakout cables (and channelization configuration).

  • Two 200-Gigabit Ethernet ports (38 and 39, mapped to logical PIC 2) that support 200-gigabit CFP2-DCO transceivers.

Note

One QSFP28 port (port 36) and one CFP2-DCO port (port 38) can operate as multiplexer ports.

Port, Interface, and PIC Mapping

The ACX5448-D does not have a physical FPC or PIC. FPC 0 refers to the router. The ports on the front panel are mapped to logical PICs as follows:

  • Ports 035 mapped to PIC 0 (interfaces xe-0/0/0 through xe-/0/0/35)

  • Ports 36 and 37 mapped to PIC 1 (interfaces et-0/1/0 and et-0/1/1)

  • Ports 38 and 39 mapped to PIC 2 (interfaces ot-0/2/0 and ot-0/2/1)

For each CFP2-DCO optical module installed in ports 38 and 39, one optical transport (ot-) interface is created. Therefore, the ACX5448-D supports two ot- interfaces—ot-0/2/0 and ot-0/2/1. You can map two 100-Gigabit Ethernet (et-) interfaces to each ot- interface, depending on the configured rate—100 Gbps or 200 Gbps—for the CFP2-DCO module. As a result, four et- interfaces are possible—et-0/2/0, et-0/2/1, et-0/2/2, and et-0/2/3.

The optical interface to et mapping is displayed in the following table:

Default Port Configuration on ACX5448-D

By default (factory-default configuration), when you power on an ACX5448-D router, the following port combinations are available:

  • 36 SFP+ ports (ports 0 through 35)—These ports can operate as native 10-Gigabit Ethernet interfaces or as 1-Gigabit Ethernet interfaces when you use 1-gigabit optics.

  • Two QSFP28 ports (36 and 37)—The interface for port 36 is not created. However, you can configure port 37 as native 100-Gigabit or 40-Gigabit Ethernet interfaces, or channelize these ports into four 25-Gigabit Ethernet or 10-Gigabit Ethernet interfaces, respectively, by using CLI configuration and breakout cables.

  • Two CFP2 ports (38 and 39)—You can configure each of the CFP2 ports as a 200-Gigabit Ethernet port.

Multiplexing on ACX5448-D Routers

As we have seen in the preceding sections, the et-0/1/0 interface is created for QSFP28 port 36 and the ot-0/2/0 interface is created for CFP2 port 38. The ot-0/2/0 interface is mapped to the et- interfaces et-0/2/0 and et-0/2/1.

The QSFP28 port 36 (interface et-0/1/0) and the CFP2 port 38 (interface et-0/2/1) operate as multiplexer (also called mux) ports.

When you start up the router, the et-0/1/0 interface on port 36 is not created by default. However, the interface et-0/2/0 (on port 38) is always available. You can enable the et-0/1/0 interface (on port 36) by running the set chassis fpc 0 cfp-to-et command and restarting the FPC by executing the restart chassis-control command. (This configuration deletes the interface et-0/2/1 on port 38.)

Therefore, you can change the factory-default port combination for the QSFP28 and CFP2 ports to the following:

  • QSFP28 ports 36 and 37—Enable the et-0/1/0 interface on port 36. You can configure ports 36 and 37 as native 100-Gigabit or 40-Gigabit Ethernet interfaces, or channelize them into four 25-Gigabit Ethernet or 10-Gigabit Ethernet interfaces, respectively, by using CLI configuration and breakout cables.

  • CFP2 ports 38 and 39—Configure port 38 as a 100-Gigabit Ethernet port and port 39 as a 200-Gigabit Ethernet port.

Enable Multiplexing by Changing the Default Configuration

In the factory-default configuration, the interface for port 36 is not created. You need to enable it and then operate it as a multiplexed port 38 (interface et-0/2/1). To change the factory-default port combination and enable the et-0/1/0 interface (port 36):

  1. Include the set chassis fpc 0 cfp-to-et command at the [edit] hierarchy level in the configuration mode.
  2. Commit the configuration.
  3. Restart the FPC.

This configuration deletes the et-0/2/1 interface (on port 38) and creates the et-0/1/0 interface (on port 36). After you change the factory-default port combination, the modified port combination will become the default port combination when you power on the device.

Note

Before changing this default behavior, plan to handle disruption of services.

Port Panel of an ACX5448-M Router

The port panel of the ACX5448-M router has the following port configurations:

  • Forty-four 10-Gigabit or 1-Gigabit Ethernet ports (0 through 43) that support small form-factor pluggable plus (SFP+) transceivers. These ports can also operate at 1-Gbps speed when you use 1-gigabit SFP optics.

  • Six 100-Gigabit Ethernet ports (44 through 49) that support quad small form-factor pluggable 28 (QSFP28) transceivers. You can channelize these ports into four 25-Gbps interfaces using breakout cables (and channelization configuration). These ports also support 40-Gbps speed, when you use QSFP+ optics. You can channelize these 40-Gbps ports into four 10-Gbps interfaces using breakout cables (and channelization configuration).

    Note

    The ACX5448-M routers support advanced security capabilities such as Media Access Control Security (MACsec). MACsec is supported only on the forty-four 10-Gigabit or 1-Gigabit Ethernet ports.

Management Port LEDs on ACX5400 Routers

The management ports (labeled MGMT) for 10/100/1000BASE-T connections on ACX5400 routers have two LEDs that indicate link status and link activity (see callout 3 and 4 in Figure 10). The right LED indicates status; the left LED indicates link activity.

The first LED is used and the remaining LEDs are not used when the port is configured as a 40-Gigabit Ethernet or 100-Gigabit Ethernet interface, and connected to a QSFP28 transceiver. All four LEDs are used when the port is configured as a 10-Gigabit Ethernet or 25-Gigabit Ethernet interface, and the port is connected using an optical split cable (breakout cable) or a direct attach copper breakout (DACBO) cable.

Fan Status LEDs on ACX5400 Routers

The fan modules on ACX5400 routers do not have any LEDs—the fan status LEDs are located next to the fan module slots on the ACX5400 chassis. Figure 13 shows the location of the LED next to the fan module.
