Software release | - Junos OS Release 8.4 and later
|
Description | - 40 Gigabit Ethernet ports
- Power requirement: 6.98 A @ 48 V (335 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-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 | 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. |
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:

Copper interface specifications—see Ethernet 10BASE, 100BASE, and 1000BASE Copper and Optical 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 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
