Software features	For more information about the software features supported on the MX2K-MPC11E, see Protocols and Applications Supported by MPC11E line cards in the MX2010 and MX2020 Routers.
Power requirements	The power numbers are measured using the following configuration: Line-rate traffic on all ports for 4-Tbps aggregate bandwidth All 40 ports configured for 100-Gbps with QSFP28 transceivers installed in all ports The default ambient temperature for MX2000 routers is set to 104° F (40° C). You can set the ambient temperature to 77° F (25° C) or 131°F (55° C) using a CLI configuration command. Maximum power: 1980 W at 104° F (40° C) + 6000 ft. (1829 m) Note: When operating the MX2K-MPC11E in ambient temperatures above the maximum normal operating temperature of 104° F (40 C) you may see a decrease in performance. This situation is normal, and the card is operating as designed. If a decrease in performance does occur, a yellow alarm appears on the system. The decrease in performance is not a permanent situation. This may occur during NEBS operating environmental conditions.
LEDs	PWR/FAIL LED: Steady green—MPC is functioning normally Slow blinking green—MPC is initializing Fast blinking green—MPC is being identified by software Red—MPC has failed QSFP Port Link/Traffic Port LED: Off—Port link is down with loss of signal Green—Port link is up with no alarms or failures Amber—Port link is down with alarms, or the port has been administratively disabled through the CLI Red—A transceiver on the port is experiencing a fault Lane LEDs (L0, L1, L2, L3): When Port 0 is channelized for 4x10-Gbps, the link status for the device connected to the channelized port is indicated by one of four lane LEDs on the MX2K-MPC11E port panel. Like the QSFP Port Link/Traffic Port LEDs, each individual lane LED has four states: off, green, amber, and red. See Configuring Rate Selectability on the MX2K-MPC11E to Enable Different Port Speeds and MPC and MIC Lane LED Scheme Overview for more details. Note: For the 40GbE and 100GbE modes, the lane LEDs are not applicable.

The MX2010 with existing power supplies can support a maximum of six MX2K-MPC11Es and maintain PSM redundancy.

MX2K-MPC11E Port Panel

The MX2K-MPC11E port panel has 40 rate-selectable (multi-rate) ports that support quad small form-factor pluggable plus (QSFP28) transceivers. The MX2K-MPC11E has eight built-in PICs, PIC0 to PIC7. Each PIC has five physical ports which constitute a logical PIC in the software. The default port speed is 100-Gbps for all ports. You can channelize Port 0 using Junos OS CLI configuration commands to create multiple independent 4x10 Gbps interfaces, and then use breakout cables to connect to other servers, storage devices, and routers. Table 1 lists the optical transceivers that support channelization. For instructions on how to channelize ports, see Configuring Rate Selectability on the MX2K-MPC11E to Enable Different Port Speeds.

Note:

When you configure different data rates for Port 0 in a PIC, the total throughput for the PIC can’t exceed 500 Gbps.

You’ll notice that the ports have colored lines above them. The colors help you to easily identify the ports that are associated with the same PIC/PFE. As shown in Figure 2, here’s what the colors mean:

Purple—Indicates an adjacent five-port PIC segment. Each port group has an adjacent five-port PIC segment.
Green—Indicates a five-port PIC segment.
Yellow—Indicates the 400-Gbps-capable ports on each PIC.

Figure 2: Port Numbering for the MX2K-MPC11E

The purple and green lines in a port group denote the five ports associated with a PIC. For example, starting with the port groups on the left side of the port panel, the five ports with a purple line above them all connect to PIC 1. The five ports with a green line above them all connect to PIC 0. The numbers and arrows below the bottom ports tell you the PIC/port number. The up arrow means that the PIC/port number is for the top port. The down arrow means that the PIC/port number is for the bottom port. The port numbering is not contiguous.

QSFP Transceivers and Port Speeds

You can plug 100-GbE optics into any of the 40 ports.

Maximum MX2K-MPC11E Support Per Chassis

The number of MX2K-MPC11E line cards that the MX2020 and MX2010 router chassis can support varies, depending upon the ambient temperature of the chassis and the PSM redundancy.
