The SRX-MIC-20GE-SFP is a Modular Interface Card (MIC) offering 20 independent 1 GbE SFP ports for SRX5000 line cards, enabling high-density fiber connectivity.
This MIC is compatible only with the SRX5K-MPC line card slot in SRX5000 series chassis and requires an SRX5K-MPC to operate.
The SRX-MIC-20GE-SFP requires Junos OS release 12.1X47-D10 or later to ensure full feature support and stability.
No. The SRX-MIC-20GE-SFP is sold without SFP optics; you must purchase compatible 1 GbE SFP modules separately.
It provides 20 independent 1 GbE SFP interfaces, each capable of hot-plug insertion and removal without system disruption.
The MIC supports Juniper-approved 1000BASE-SX, LX, ZX, T, and CWDM/DWDM SFP transceivers for multi-mode and single-mode fiber links.
Yes. You can deploy mixed SFP types across ports, provided each transceiver is Juniper-qualified and operates within the module’s specifications.
Each SFP port supports up to 1 Gbps of full-duplex throughput, with aggregate module performance determined by the SRX5K-MPC capabilities.
Yes. The MIC and its SFP transceivers support hot-swap operations, allowing maintenance without powering down the chassis.
Power off the SRX5000 chassis, insert the MIC into an SRX5K-MPC slot, secure the module, power on, and verify detection via the CLI.
Typical power consumption is 8 W (maximum 10 W) for the MIC alone; total chassis power depends on all installed modules and line cards.
The module operates between 0 °C to 40 °C (32 °F to 104 °F) and 5% to 90% non-condensing relative humidity.
Manage the module through Junos OS CLI, J-Web GUI, or Juniper Network Director for real-time monitoring, configuration, and diagnostics.
When paired with redundant SRX5K-MPCs, the MIC supports stateful failover and non-stop services to ensure minimal traffic disruption.
The MIC fits data center top-of-rack aggregation, campus edge security, and service provider peering where dense 1 GbE fiber interfaces are required.
The SRX-MIC-20GE-SFP comes with a one-year limited hardware warranty and Juniper’s Software Advantage support for software updates and technical assistance.
