Port Panel of an ACX5048 Router

The port panel of the ACX5048 supports up to a maximum 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. 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 pluggable plus (QSFP+) transceivers or QSFP+. 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.

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 configured as uplinks or Virtual Chassis ports (VCPs). Although the 104 physical ports of the ACX5096 would map to 128 logical ports using channelization, only 104 logical ports are supported.

• Router Ports

• Channelizing Interfaces

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

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.

Channelizing Interfaces

The port panel of an ACX5096 supports up to a maximum of 104 logical 10 GbE ports that can be distributed over 96 small form-factor pluggable plus (SFP+) and 8 quad small-form factor pluggable plus (QSFP+) transceivers . Because of an 104 port 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 system modes 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 no packet 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.

Chassis Status LEDs on an ACX5000 Router

The ACX5000 routers has four status LEDs on the FRU side of the chassis, next to the management ports (see Figure 7).

Table 1 describes the chassis status LEDs on an ACX5000 router, their colors and states, and the status they indicate. You can view the colors of the three LEDs remotely through the CLI by issuing the operational mode command show chassis lcd.

Management Port LEDs on an ACX5000 Router

The management ports (labeled C0 for 10/100/1000 Base-T and C1 for 10/100/1000 Base-T and SFP 1000 Base-X connections) on an ACX5000 router have two LEDs that indicate link status and link activity (see Figure 8). The left LED indicates status; the right LED indicates link/activity.

Table 2 describes the management port LEDs.

Access Port and Uplink Port LEDs on an ACX5000 Router

The Link/Activity and Status LED configuration for ACX5000 routers use bi-colored LEDs. The link LED indicates link activity or a fault. The status LED indicates transceiver presence. See Table 3 to locate the position and type of LED for your ACX5000 model.

Table 3: ACX5000 Access Port and Uplink LED Locations

Model	Port Type	Indicators	Location
ACX5048	SFP+	Link Status
ACX5096	SFP+	Link Status

Table 4 describes how to interpret the SFP+ port LEDs.

As shown in Table 3, there are four bi-color LEDs for each QSFP+ port. The first LED is used and the remaining LEDs are not used when the interface is configured for 40-Gigabit Ethernet and connected to a QSFP+ transceiver. All four LEDs are used when the interface is configured for 10-Gigabit Ethernet and the port is connected using an optical split cable or a copper DACBO cable. Table 5 describes how to interpret the QSFP+ LEDs.
