EX9253 Line Cards

 

EX9253-6Q12C Line Card

The line cards in EX9253 switches combine a Packet Forwarding Engine and Ethernet interfaces in a single assembly. Line cards are field-replaceable units (FRUs) that you can install in the line card slots on the front of the switch chassis. Line cards are hot-insertable and hot-removable: You can remove and replace them without powering off the switch or disrupting switch functions. To maintain proper cooling, you must install a replacement line card or a blank panel in the line card slot shortly after removing a line card from the chassis.

Line Card Components

The EX9253-6Q12C line card has:

  • Six built-in QSFP+ ports, each of which can house a combination of QSFP+ transceivers or breakout cables. These ports operate at 40 Gbps speed. By default, the ports operate with 4x10 Gbps interfaces and support breakout cables. If you need to connect a QSFP+ transceiver to the port, you must configure a 40 Gbps interface on the port by using the command set chassis fpc fpc-slot pic pic-slot port port-number 40g. The ports are labeled 0 through 5. The ports support rate selectability and remote port identification.

  • 12 built-in QSFP28 ports, each of which can house a combination of QSFP28 transceivers, QSFP+ transceivers, or breakout cables. These ports can operate at 40 Gbps and 100 Gbps speeds. By default, the ports operate with 4x10 Gbps interfaces and support breakout cables. If you need to connect a QSFP+ transceiver to the port, you must configure a 40 Gbps interface on the port. If you need to connect a QSFP28 transceiver to the port, you must configure a 100 Gbps interface on the port by using the command set chassis fpc fpc-slot pic pic-slot port port-number 100g. The ports are labeled 0 through 11. The ports support rate selectability and remote port identification.

  • Port LEDs—One LED on each QSFP+ port and two LEDs on each QSFP28 port, which indicates the link status and activity on the port. See MPC and MIC Lane LED Scheme Overview.

  • Lane LEDs

  • Line card LED—An LED labeled OK/FAIL, which indicates the status of the line card.

  • ONLINE LED—An LED labeled ONLINE, which indicates if the line card is online.

  • OFFLINE button—A button to take the line card offline before removing it

The ports are divided into two port groups. The six QSFP+ ports labeled 0 through 5 form one port group, PIC 0. The 12 QSFP28 ports labeled 0 through 11 form the other port group, PIC 1. The ports in each group share 1.2 terabits of bandwidth. Thus, you can transmit up to 1.2 terabits of traffic through a port group, without packet drop.

Port LEDs and Lane LEDs on EX9253-6Q12C Line Card

You can select a port operating in a breakout mode for an individual lane display, either periodically or when the request chassis port-led command is executed. Similar to the port status LEDs, the lane LED supports four states defined by the color or the LED status—Off, Green, Amber, and Red.

The following are the port LED display modes:

  • Normal—The port status LED represents port state or a breakout port state. By default, the port status display mode is Normal.

  • Lane display—An array of lane status LEDs displays the status of each individual lane for the selected port. The lane display is ON when the software cycles through ports for lane status display. One port is selected at a time, and the display mode for that particular port switches to lane display mode. The other ports remain in normal display mode.

  • Port location—The port location mode is ON when a remote operator initiates a port location command for a port or a group of ports. The request chassis port-led command temporarily overrides periodic software port selection for the lane display; all ports on an interface card that are not selected for port location switch to Normal mode, and selected ports switch to port location mode. If only one port is selected for port location, then the corresponding lane LEDs are applicable. However, if the selected port is in breakout mode, then all lane LEDs are applicable. If not in breakout mode, only lane 0 LED displays the port status. If more than one port is selected for port location, then the lane LEDs are disabled.

The following factors trigger a change in the port LED color:

  • Change in the port state. For example, loss of signal (LOS) to no LOS, remote fault, or local fault.

  • Insertion or removal or a transceiver

  • Change in configuration

  • Activation or deactivation of port location feature

  • Selection of breakout port for lane display

Note

Ports with all individual links in Up state are skipped and are not considered for lane display, thereby reducing the time needed to cycle through all the ports.

Table 2 describes the state and color rules for the port LEDs. These rules help in determining the port LED color. When port location mode is activated, the port LED state or color can be determined from the column titled Port Location ON. If the breakout port is selected for the lane status display, then port LED state or color can be determined from the column titled Lane Display.

  • Six built-in QSFP+ ports, each of which can house a combination of QSFP+ transceivers or breakout cables. These ports operate at 40 Gbps speed. By default, the ports operate with 4x10 Gbps interfaces and support breakout cables. If you need to connect a QSFP+ transceiver to the port, you must configure a 40 Gbps interface on the port by using the command set chassis fpc fpc-slot pic pic-slot port port-number 40g. The ports are labeled 0 through 5. The ports support rate selectability and remote port identification.

  • 12 built-in QSFP28 ports with MACsec capability, each of which can house a combination of QSFP28 transceivers, QSFP+ transceivers, or breakout cables. These ports can operate at 40 Gbps and 100 Gbps speeds. By default, the ports operate with 4x10 Gbps interfaces and support breakout cables. If you need to connect a QSFP+ transceiver to the port, you must configure a 40 Gbps interface on the port. If you need to connect a QSFP28 transceiver to the port, you must configure a 100 Gbps interface on the port by using the command set chassis fpc fpc-slot pic pic-slot port port-number 100g. The ports are labeled 0 through 11. The ports support rate selectability and remote port identification.

  • Port LEDs—One LED on each QSFP+ port and two LEDs on each QSFP28 port, which indicates the link status and activity on the port. See MPC and MIC Lane LED Scheme Overview.

  • Lane LEDs

  • Line card LED—An LED labeled OK/FAIL, which indicates the status of the line card.

  • ONLINE LED—An LED labeled ONLINE, which indicates if the line card is online.

  • OFFLINE button—A button to take the line card offline before removing it

The ports are divided into two port groups. The six QSFP+ ports labeled 0 through 5 form one port group, PIC 0. The 12 QSFP28 ports labeled 0 through 11 form the other port group, PIC 1. The ports in each group share 1.2 terabits of bandwidth. Thus, you can transmit up to 1.2 terabits of traffic through a port group, without packet drop.

Port LEDs and Lane LEDs on EX9253-6Q12C-M Line Card

You can select a port operating in a breakout mode for an individual lane display, either periodically or when the request chassis port-led command is executed. Similar to the port status LEDs, the lane LED supports four states defined by the color or the LED status—Off, Green, Amber, and Red.

The following are the port LED display modes:

  • Normal—The port status LED represents port state or a breakout port state. By default, the port status display mode is Normal.

  • Lane display—An array of lane status LEDs displays the status of each individual lane for the selected port. The lane display is ON when the software cycles through ports for lane status display. One port is selected at a time, and the display mode for that particular port switches to lane display mode. The other ports remain in normal display mode.

  • Port location—The port location mode is ON when a remote operator initiates a port location command for a port or a group of ports. The request chassis port-led command temporarily overrides periodic software port selection for the lane display; all ports on an interface card that are not selected for port location switch to Normal mode, and selected ports switch to port location mode. If only one port is selected for port location, then the corresponding lane LEDs are applicable. However, if the selected port is in breakout mode, then all lane LEDs are applicable. If not in breakout mode, only lane 0 LED displays the port status. If more than one port is selected for port location, then the lane LEDs are disabled.

The following factors trigger a change in the port LED color:

  • Change in the port state. For example, loss of signal (LOS) to no LOS, remote fault, or local fault.

  • Insertion or removal or a transceiver

  • Change in configuration

  • Activation or deactivation of port location feature

  • Selection of breakout port for lane display

Note

Ports with all individual links in Up state are skipped and are not considered for lane display, thereby reducing the time needed to cycle through all the ports.

Table 6 describes the state and color rules for the port LEDs. These rules help in determining the port LED color. When port location mode is activated, the port LED state or color can be determined from the column titled Port Location ON. If the breakout port is selected for the lane status display, then port LED state or color can be determined from the column titled Lane Display.
