Интерфейсный модуль Juniper DPCE-X-Q-40GE-SFP

Software release

• Junos OS Release 8.5 and later

Description

• 40 Gigabit Ethernet ports
• Power requirement: 7.6 A @ 48 V (365 W)
• Weight: 13.1 lb (5.9 kg)
• Supports large Ethernet frame sizes for more efficient throughput across the intra-POP network
• Model number: DPCE-X-Q-40GE-SFP
• Name in the CLI: DPCE 40x 1GE X EQ

Hardware features

• High-performance throughput on each port at speeds up to 1 Gbps
• Autonegotiation between Gigabit Ethernet circuit partners
• Full-duplex mode
• Maximum transmission units (MTUs) of up to 9192 bytes
• Enhanced ASICs for increased performance and scalability of Layer 2 features

Software features

• Optical diagnostics and related alarms
• See Protocols and Applications Supported by Enhanced Queuing Ethernet Services DPCs (DPCE-X-Q) for information about the protocols and applications that this DPC supports.

Note: The routing table is limited to 32,000 IP routes. This limitation applies to any manner in which the routes are learned, such as OSPF, RIP, and so on. The DPC supports BGP for L2 VPNs only.

Interfaces

Syntax: ge-fpc/pic/port where:

• fpc: Slot in the router where the DPC is installed
• pic: 0 (bottom left row of 10 ports), 1 (bottom right row of 10 ports), 2 (top left row of 10 ports), or 3 (top right row of 10 ports)
• port: 0 through 9

For example, ge-1/3/0 is the interface for port 0 in the top right row of 10 ports on a DPC installed in slot 1.

Cables and connectors

• You can install any transceiver supported by the DPC. For information about installing and removing transceivers, see the hardware guide for your router.
• Fiber-optic small form-factor pluggable (SFP) transceivers:

Connector: Duplex LC/PC (Rx and Tx)

1000BASE-EX (model number: SFP-GE40KM)

1000BASE-LH (model number: SFP-1GE-LH)

1000BASE-LX (model number: SFP-1GE-LX)

1000BASE-SX (model number: SFP-1GE-SX)

• Optical interface specifications—see Gigabit Ethernet 1000BASE Optical Interface Specifications
• Copper SFP transceivers:

Connector: Four-pair, Category 5 shielded twisted-pair connectivity through an RJ-45 connector

1000BASE-T (model number: SFP-1GE-T)

Pinout: MDI crossover

Length: 328 ft/100 m

• Copper interface specifications—see Gigabit Ethernet 1000BASE-T Copper Interface Specifications
• Bidirectional SFP transceivers:

Connector: Duplex LC/PC (Rx and Tx)

1000BASE-BX (model number pairs: SFP-GE10KT13R14 with SFP-GE10KT14R13, SFP-GE10KT13R15 with SFP-GE10KT15R13, SFP-GE40KT13R15 with SFP-GE40KT15R13)

• Optical interface specifications—see Fast Ethernet and Gigabit Ethernet Bidirectional SFP Optical Interface Specifications

Note: Do not install Gigabit Ethernet SFPs in the SONET/SDH port. The port will not recognize the SFP.

LEDs

OK/FAIL LED, one bicolor:

• Steady green—DPC is functioning normally.
• Blinking green—DPC is transitioning online or offline.
• Red—DPC has failed.

Link LED, one green per port:

• Off—No link.
• On steadily—Link is active.

The Link LEDs are labeled in groups of five:

• 0/0 for 0/0 through 0/4
• 0/5 for 0/5 through 0/9
• 1/0 for 1/0 through 1/4
• 1/5 for 1/5 through 1/9
• 2/0 for 2/0 through 2/4
• 2/5 for 2/5 through 2/9
• 3/0 for 3/0 through 3/4
• 3/5 for 3/5 through 3/9
