MX240 Line Card Components and Descriptions

A Dense Port Concentrator (DPC) is optimized for Ethernet density and supports up to 40 Gigabit Ethernet or four 10-Gigabit Ethernet ports (see Figure 1). Other combinations of Gigabit Ethernet and 10-Gigabit ports are available in various DPC models. For more information about these models, see the MX Series 5G Universal Routing Platform Interface Module Reference.

The DPC assembly combines packet forwarding and Ethernet interfaces on a single board, with either two or four 10-Gbps Packet Forwarding Engines. Each Packet Forwarding Engine consists of one I-chip for Layer 3 processing and one Layer 2 network processor. The DPCs interface with the power supplies and Switch Control Boards (SCBs).

The router has two dedicated line card slots for DPCs, MPCs, or FPCs. DPCs install horizontally in the front of the router (see Figure 1). One multifunction slot numbered 1/0 supports either one DPC or one SCB. The DPC slots are numbered 1/0, 1, and 2, bottom to top. A DPC can be installed in any slot on the router that supports DPCs.

You can install any combination of DPC types in the router.

DPCs are hot-removable and hot-insertable. When you install a DPC in an operating router, the Routing Engine downloads the DPC software, the DPC runs its diagnostics, and the Packet Forwarding Engines housed on the DPC are enabled. Forwarding on other DPCs continues uninterrupted during this process.

If a slot is not occupied by a DPC or an SCB, a blank panel must be installed to shield the empty slot and to allow cooling air to circulate properly through the router.

Figure 1 shows typical DPCs supported on the MX240 router. For more information about DPCs, see the MX Series 5G Universal Routing Platform Interface Module Reference.

Figure 2: DPC Installed Horizontally in the MX240 Router

Each port on a DPC corresponds to a unique interface name in the CLI.

In the syntax of an interface name, a hyphen (-) separates the media type from the DPC number (represented as an FPC in the CLI). The DPC slot number corresponds to the first number in the interface. The second number in the interface corresponds to the logical PIC number. The last number in the interface matches the port number on the DPC. Slashes (/) separate the DPC number from the logical PIC number and port number.

type-fpc/pic/port

• type—Media type, which identifies the network device. For example:

  • ge—Gigabit Ethernet interface

  • so—SONET/SDH interface

  • xe—10-Gigabit Ethernet interface

  For a complete list of media types, see Interface Naming Overview.

• fpc—Slot in which the DPC is installed. On the MX240 router, the DPCs are represented in the CLI as FPC 0 through FPC 2.

• pic—Logical PIC on the DPC. The number of logical PICs varies depending on the type of DPC. For example, a:

  • 20-port Gigabit Ethernet DPC has two logical PICs, numbered 0 through 1.

  • 40-port Gigabit Ethernet DPC has four logical PICs, numbered 0 through 3.

  • 2-port 10-Gigabit Ethernet DPC has two logical PICs, numbered 0 through 1.

  • 4-port 10-Gigabit Ethernet DPC has four logical PICs, numbered 0 through 3.

  For more information on specific DPCs, see DPCs Supported on MX240, MX480, and MX960 Routers in the MX Series 5G Universal Routing Platform Interface Module Reference.

• port—Port number.

The MX240 router supports up to three DPCs that install horizontally and are numbered from bottom to top.

Figure 3 shows a 40-port Gigabit Ethernet DPC with SFP installed in slot 2 on the MX240 router.

Figure 3: MX240 DPC Interface Port Mapping

The DPC contains four logical PICs, numbered PIC 0 through PIC 3 in the CLI. Each logical PIC contains 10 ports numbered 0 through 9.

The show chassis hardware command output displays a 40-port Gigabit Ethernet DPC with SFP (DPCE-R-40GE-SFP) installed in DPC slot 2. The DPC is shown as FPC 2 and the DPC’s four logical PICs — 10x 1GE(LAN) — are shown as PIC 0 through PIC 3.

The show interfaces terse command output displays the Gigabit Ethernet interfaces that correspond to the 40 ports located on the DPC.

Two LEDs, located on the craft interface above the DPC, display the status of the DPC and are labeled OK and FAIL. For more information about the DPC LEDs on the craft interface, see MX240 Component LEDs on the Craft Interface.

Each DPC also has LEDs located on the faceplate. For more information about LEDs on the DPC faceplate, see the “LEDs” section for each DPC in the MX Series 5G Universal Routing Platform Interface Module Reference.

Table 1 lists the DPCs supported by the MX240, MX480, and MX960 routers.

A Flexible PIC Concentrator (FPC) occupies two DPC slots on an MX Series router. The DPC slots are numbered 1/0, 1, and 2, bottom to top. One FPC can be installed horizontally in either slots 1/0 and 1, or slots 1 and 2 on the front of the router (see Figure 5). The interface corresponds to the lowest numbered DPC slot for which the FPC is installed.

Figure 4 shows typical FPCs supported on the MX240 router.

Figure 4: Typical FPCs Supported on the MX240 Router

If a slot is not occupied by a DPC, an FPC, or an SCB, a blank panel must be installed to shield the empty slot and to allow cooling air to circulate properly through the router.

Each FPC supports up to two PICs. On an FPC2, one Packet Forwarding Engine receives incoming packets from the PICs installed on the FPC and forwards them through the switch planes to the appropriate destination port. On an FPC3, two Packet Forwarding Engines receive incoming packets from the PICs installed on the FPC and forwards them through the switch planes to the appropriate destination port. The FPCs interface with the power supplies and SCBs.

FPCs are hot-removable and hot-insertable, as described in MX240 Component Redundancy. When you install an FPC into a functioning router, the Routing Engine downloads the FPC software, the FPC runs its diagnostics, and the PICs, housed on the FPC, are enabled. Forwarding continues uninterrupted during this process. When you remove or install an FPC, packet forwarding between other DPCs or FPCs is not affected.

Figure 5: FPC Installed in the MX240 Router Chassis

Two LEDs, located on the craft interface above the FPC, that display the status of the FPC and are labeled OK and FAIL. For more information about the FPC LEDs located on the craft interface, see MX240 Component LEDs on the Craft Interface.

An FPC occupies two slots when installed in an MX240, MX480, or MX960 router. The maximum number of supported FPCs varies per router:

• MX960 router—6 FPCs

• MX480 router—3 FPCs

• MX240 router—1 FPC

Table 2 lists FPCs supported by MX240, MX480, and MX960 routers.

PICs provide the physical connection to various network media types, receiving incoming packets from the network and transmitting outgoing packets to the network. During this process, each PIC performs framing and line-speed signaling for its media type. Before transmitting outgoing data packets, the PICs encapsulate the packets received from the FPCs. Each PIC is equipped with an ASIC that performs control functions specific to the media type of that PIC.

PICs are hot-removable and hot-insertable. You can install up to two PICs in the slots in each FPC. PICs used in an FPC2 have captive screws at their upper and lower corners. PICs used in a Type 3 FPC have an upper ejector handle and a lower captive screw.

Each port on a PIC corresponds to a unique interface name in the CLI.

In the syntax of an interface name, a hyphen (-) separates the media type from the FPC number (represented as an FPC in the CLI). The FPC slot number corresponds to the first number in the interface. The second number in the interface corresponds to the PIC number. The last number in the interface matches the port number on the PIC. Slashes (/) separate the FPC slot number from the PIC number and port number:

type-fpc/pic/port

• type—Media type, which identifies the network device. For example:

  • ge—Gigabit Ethernet interface

  • so—SONET/SDH interface

  • xe—10-Gigabit Ethernet interface

  For a complete list of media types, see Interface Naming Overview.

• fpc—Lowest slot number in which the FPC is installed. On the MX240 router, the FPC occupies two line card slots and is represented in the CLI as FPC 0 or FPC 1.

• pic—PIC number, 0 or 1 depending on the FPC slot.

  For more information on specific PICs, see PICs Supported by MX240, MX480, and MX960 Routers in the MX Series 5G Universal Routing Platform Interface Module Reference.

• port—Port number.

The FPC installs horizontally in either slots 1/0 and 1, or slots 1 and 2 and accepts up to two PICs.

Figure 6 shows a Channelized OC12/STM4 Enhanced IQ (IQE) PIC with SFP installed in PIC slot 0 of an FPC installed in slot 1 and slot 2.

Figure 6: MX240 PIC Interface Port Mapping

The show chassis hardware command output displays a Channelized OC12/STM4 Enhanced IQ (IQE) PIC (4x CHOC12 IQE SONET) installed in MX FPC Type 2.

The show interfaces terse command output displays the channelized SONET OC12 interfaces (coc12), that correspond to the four ports located on the PIC.

Each PIC has LEDs located on the faceplate. For more information about LEDs on the PIC faceplate, see the “LEDs” section for each PIC in the MX Series 5G Universal Routing Platform Interface Module Reference.

Table 3 lists the PICs supported by MX240, MX480, and MX960 routers.

The following tables provide a compatibility matrix for the MICs currently supported by MPC1, MPC2, MPC3, MPC6, MPC8, and MPC9 on MX240, MX480, MX960, MX2008, MX2010, MX2020, and MX10003 routers. Each table lists the first Junos OS release in which the MPC supports the MIC. For example, Junos OS Release 10.2 is the first release in which the MX-MPC1-3D supports the Gigabit Ethernet MIC with SFP. An en dash indicates that the MIC is not supported.

Modular Interface Cards (MICs) install into Modular Port Concentrators (MPCs) and provide the physical connections to various network media types. MICs allow different physical interfaces to be supported on a single line card. You can install MICs of different media types on the same router as long as the router supports those MICs.

MICs receive incoming packets from the network and transmit outgoing packets to the network. During this process, each MIC performs framing and high-speed signaling for its media type. Before transmitting outgoing data packets through the MIC interfaces, the MPCs encapsulate the packets received.

MICs are hot-removable and hot-insertable. You can install up to two MICs in the slots in each MPC.

The following tables list the first supported Junos OS release for the MX Series.

• Table 11 lists the first supported Junos OS release for MICs on MX240, MX480, MX960, and MX2008 routers.

• Table 12 lists the first supported Junos OS release for MICs on MX2010 and MX2020 routers.

• Table 13 list the first supported Junos OS release for MICs on MX5, MX10, and MX40 routers.

• Table 14 lists the first supported Junos OS release for MICs on MX80 and MX104 routers.

• Table 15 lists the first supported Junos OS release for MICs on MX10003 router.

Each MIC has LEDs located on the faceplate. For more information about LEDs on the MIC faceplate, see the “LEDs” section for each MIC in the MX Series 5G Universal Routing Platform Interface Module Reference.

Each port on a MIC corresponds to a unique interface name in the CLI.

In the syntax of an interface name, a hyphen (-) separates the media type from the MPC number (represented as an FPC in the CLI). The MPC slot number corresponds to the first number in the interface. The second number in the interface corresponds to the logical PIC number. The last number in the interface matches the port number on the MIC. Slashes (/) separate the MPC number from the logical PIC number and port number:

type-fpc/pic/port

• type—Media type, which identifies the network device. For example:

  • ge—Gigabit Ethernet interface

  • so—SONET/SDH interface

  • xe—10-Gigabit Ethernet interface

  For a complete list of media types, see Interface Naming Overview.

• fpc—Slot in which the MPC is installed. On the MX240 router, the MPCs are represented in the CLI as FPC 0 through FPC 2.

• pic—Logical PIC on the MIC, numbered 0 or 1 when installed in slot 0, and 2 or 3 when installed in slot 1. The number of logical PICs varies depending on the type of MIC. For example, a:

  • 20-port Gigabit Ethernet MIC has two logical PICs, numbered 0 and 1 when installed in slot 0, or 2 and 3 when installed in slot 1.

  • 4-port 10-Gigabit Ethernet MIC has two logical PICs numbered 0 and 1 when installed in slot 0, or 2 and 3 when installed in slot 1.

  • 100-Gigabit Ethernet MIC with CFP has one logical PIC numbered 0 when installed in slot 0, or 2 when installed in slot 1.

  For more information on specific MICs, see MICs Supported by MX Series Routers in the MX Series 5G Universal Routing Platform Interface Module Reference.

• port—Port number.

The MX240 router supports up to three MPCs that install horizontally and are numbered from bottom to top. Each MPC accepts up to two MICs.

Figure 7 shows an example of a 20-port Gigabit Ethernet MIC with SFP installed in slot 0 of an MPC in slot 2.

Figure 7: MX240 MIC Interface Port Mapping

The MIC contains two logical PICs, numbered PIC 0 through PIC 1 in the CLI. Each logical PIC contains 10 ports numbered 0 through 9.

The show chassis hardware command output displays a 20-port Gigabit Ethernet MIC with SFP — 3D 20x 1GE(LAN) SFP — installed in slot 0 of an MPC in slot 2. The MPC (MPC Type 2 3D EQ) is shown as FPC 2 in the CLI. The MIC’s two logical PICs — 10x 1GE(LAN) SFP — are shown as PIC 0 and PIC 1.

The show interfaces terse command output displays the Gigabit Ethernet interfaces that correspond to the 20 ports located on the MIC.

Modular Port Concentrators (MPCs) provide packet forwarding services. The MPCs are inserted into a slot in a router. Modular Interface Cards (MICs) provide the physical interfaces and install into the MPCs. You can install up to two MICs of different media types on the same router as long as the router supports those MICs.

A specialized fixed configuration MPC provides higher port density over MICs and combines packet forwarding and Ethernet interfaces onto a single line card. The fixed configuration MPC is inserted into a slot in a router and contains no slots for MICs.

MICs receive incoming packets from the network and transmit outgoing packets to the network. During this process, each MIC performs framing and high-speed signaling for its media type. Before transmitting outgoing data packets through the MIC interfaces, the MPCs encapsulate the packets received. Each MPC is equipped with up to four Junos Trio chipsets, which perform control functions tailored to the MPC’s media type. The MPCs interface with the power supplies and Switch Control Boards (SCBs). You must install redundant SCBs to support full line-rate.

The MX240 router supports up to three MPCs. You must install a high-capacity fan tray to use an MPC. For power requirements, see Calculating Power Requirements for MX240 Routers.

The router has two dedicated line card slots for DPCs, MPCs, or FPCs. MPCs install horizontally in the front of the router (see Figure 8). One multifunction slot numbered 1/0 supports either one line card or one SCB. The line card slots are numbered 1/0, 1, and 2, bottom to top. An MPC can be installed in any slot on the router that supports MPCs. You can install any combination of line card types in the router.

When a slot is not occupied by an MPC or other line card, you must insert a blank DPC panel to fill the empty slot and ensure proper cooling of the system.

MPCs are hot-removable and hot-insertable. When you install an MPC in an operating router, the Routing Engine downloads the MPC software, the MPC runs its diagnostics, and the Packet Forwarding Engines housed on the MPC are enabled. Forwarding on other MPCs continues uninterrupted during this process.

Figure 8 shows a typical MPC supported on the MX240 router. Figure 9 shows an MPC installed horizontally in the MX240 Router. For more information about MPCs, see the MX Series 5G Universal Routing Platform Interface Module Reference.

Two LEDs, located on the craft interface above the MPC, display the status of the line cards and are labeled OK and FAIL. For more information about the line card LEDs on the craft interface, see MX240 Component LEDs on the Craft Interface.

Each MPC also has LEDs located on the faceplate. For more information about LEDs on the MPC faceplate, see the “LEDs” section for each MPC in the MX Series 5G Universal Routing Platform Interface Module Reference.

Table 16 lists the MPCs and their first supported Junos OS release on MX240, MX480, MX960, MX2008, MX2010, MX2020, and MX10003 routers.

The Application Services Modular Line Card (AS MLC) is an X86-based card for MX960, MX480, and MX240 routers to deliver integrated application service solutions. See Figure 10. The first application that network operators can take advantage of is the Junos Content Encore system, a high-throughput, solid state storage platform for media rich content delivery. Additionally, the AS MLC can serve as the platform for Juniper Networks JunosV App Engine, powering a host of network applications directly embedded into your MX Series 5G Universal Routing Platforms.

AS MLC is modular and decouples CPU and storage in individual field-upgradeable units. The AS MLCs are designed to enable application throughput up to 50 Gbps and a storage capacity of 400 gigabytes (GB) of NAND Flash.

• MX240 SCB, Power Supply, and Cooling System Requirements for AS MLC

Two LEDs (CPU and AP) indicate the status of the AS MSC and are located on the AS MSC. Table 17 describes the functions of the AS MSC LEDs.

The Application Services Modular Processing Card (AS MXC) is a pluggable X86-based card that can be inserted into the lower slot of the Application Services Modular Line Card (AS MLC). The AS MXC serves as the processing card for the Junos Content Encore system and contains the two X86, Intel 8-core processors with interface ability greater than 80 Gbps. The AS MXC (see Figure 11) is equivalent to a PIC or MIC (Modular Interface Card).

AS MXCs are hot-removable and hot-insertable. One MXC can be installed in the lower slot of each AS MLC. Each MXC has these components:

• Two 8-core Intel processors—Contains eight execution cores with Ring Interconnect architecture. Each core supports two threads, up to 16 threads per socket.

• 64 GB DRAM—On DIMM sockets.

• LEDs—Two LEDs on the faceplate display the CPU and application status.
