Software release	20-port: Junos OS Release 9.1 and later 40-port: Junos OS Release 8.5 and later
Description	20 or 40 Gigabit Ethernet ports Power requirement: 20-port: 4.2 A @ 48 V (200 W) 40-port: 7.6 A @ 48 V (365 W) Weight: 20-port: 13 lb (5.9 kg) 40-port: 13.1 lb (5.9 kg) Supports large Ethernet frame sizes for more efficient throughput across the intra-POP network Model numbers: 20-port: DPCE-R-Q-20GE-SFP 40-port: DPCE-R-Q-40GE-SFP
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 IP Services DPCs (DPCE-R-Q) for information about the protocols and applications that this DPC supports.
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: 20-port: 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 40-port: 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
