Q
What types of modules and line cards are available for the Juniper MX2020 router?
A
Juniper MX2020 supports MPC (Modular Port Concentrator) line cards including MPC10, MPC11, MPC12, and MPC14, each offering scalable port counts and interface types from 10GbE to 400GbE.
Q
How do I determine the right line card for my MX2020 deployment?
A
Select a line card based on required interface speeds, port density, and traffic patterns—MPC10/MPC11 for 100G aggregation, MPC12 for 200G high density, and MPC14 for cloud-scale 400G applications.
Q
What is the maximum throughput per module slot in the MX2020?
A
Each MX2020 slot delivers up to 2.5 Tbps of bandwidth, supporting up to 20 Tbps per Router Engine when fully populated with high-density line cards.
Q
Are MX2020 modules hot-swappable?
A
Yes, all MX2020 line cards and MPC modules are hot-swappable, enabling live upgrades and service continuity without system downtime.
Q
How many MPC line cards can the MX2020 chassis accommodate?
A
The MX2020 chassis supports up to 18 MPC line cards, providing up to 360 ports of 100GbE or scalable equivalents in higher-speed modules.
Q
What power requirements do MX2020 modules have?
A
MX2020 modules draw between 800W and 1,800W depending on line card type, and the chassis requires redundant AC or DC power supplies for high availability.
Q
Does the MX2020 support advanced features like EVPN and Segment Routing?
A
Yes, MX2020 line cards support EVPN, MPLS Segment Routing, QoS, and full-featured JUNOS software for carrier-grade service deployment.
Q
Can I mix different MPC modules in a single MX2020 chassis?
A
Yes, the MX2020 allows mixed MPC line card deployment, enabling flexible port-speed configurations and incremental capacity upgrades.
Q
What cooling mechanisms do MX2020 modules use?
A
MX2020 modules leverage front-to-back forced-air cooling with redundant fan trays to maintain optimal operating temperatures under full load.
Q
How do I upgrade an existing MX2020 line card?
A
Perform an online package upgrade via Junos CLI and use the restart-on-fail feature to minimize service disruption when installing new modules.
Q
What monitoring tools are available for MX2020 modules?
A
Use Junos Telemetry Interface, SNMP, and Juniper Healthbot for real-time performance metrics, module status, and proactive fault detection.
Q
Is there a licensing requirement for MX2020 line cards?
A
No additional license is required for basic routing features; advanced services like MACsec or SRv6 may require feature-based licenses in Junos.
Q
What fiber interfaces are supported on MX2020 cards?
A
MX2020 cards support SFP28, QSFP28, QSFP56, QSFP-DD, and CFP2DCO transceivers for single-mode and multi-mode fiber applications up to 400G.
Q
What is the warranty and support for MX2020 modules?
A
Juniper provides a one-year limited warranty for hardware with options to extend support to 3–5 years through Juniper Care and advanced replacement.
Q
How does the MX2020 improve network scalability?
A
By offering high-density 400G line cards, modular expansion slots, and non-blocking fabric, the MX2020 delivers up to 80 Tbps system throughput for growing networks.
