What is the maximum number of 100GbE ports supported by a single QFX10008 chassis?
A single QFX10008 supports up to 240 100GbE ports when fully populated with appropriate line cards. This is achieved through eight line card slots, each capable of hosting high-density 100GbE line cards with QSFP28 transceiver support. This density makes it ideal for consolidating multiple smaller switches into one chassis.
Does the QFX10008 support redundant Routing Engines and automatic failover?
Yes, the QFX10008 includes dual Routing Engines with 1.8 GHz multi-core CPUs and up to 128 GB DDR3 ECC memory per engine. Automatic failover ensures transparent network recovery during control-plane failures. Additionally, the chassis provides 4+1 redundant hot-swappable power supplies and 5+1 switch fabric redundancy for comprehensive high availability.
What protocols and network architectures does the QFX10008 support?
The QFX10008 supports Layer 2 and Layer 3 fabrics, Juniper MC-LAG, BGP, OSPF, IS-IS, MPLS, VXLAN, and EVPN. It runs Junos OS and can be managed via CLI, Web, SNMP, NETCONF, and Junos Space. This protocol support enables deployment in diverse network designs including datacenter fabrics, service provider networks, and DC interconnect scenarios.
What are the power requirements and cooling specifications?
The QFX10008 accepts 100–240 VAC or -48/-60 VDC input with 4+1 redundant power supplies rated at 2,700W AC or 9,300W DC options. Maximum power consumption is 37.2 kW when fully loaded. It features front-to-back airflow with dual hot-swappable fan trays. Operating temperature range is 0–40°C with acoustic noise under 72 dBA at 25°C.
Can the QFX10008 be upgraded to support 400GbE in the future?
Yes, the QFX10008 is 400GbE-ready. The modular 8-slot design and high switching capacity (48 Tbps) provide a foundation for future line card upgrades. Organizations can deploy 100GbE today and upgrade to 400GbE line cards as technology matures and costs decrease, protecting capital investment.
What is the physical footprint and rack space requirement?
The QFX10008 is 13U tall and measures 35.06 inches (H) × 25.00 inches (W) × 30.48 inches (D). It weighs 318.4 lbs when fully configured. Up to three QFX10008 chassis can fit in a standard 42U rack with adequate cooling and power distribution, enabling high-density spine deployments in large datacenters.
Are all components hot-swappable and field-replaceable?
Yes, all key QFX10008 components are field-replaceable units (FRUs), including power supplies, fan trays, Routing Engines, line cards, and switch fabric cards. Hot-swappable design enables non-disruptive maintenance and upgrades without requiring chassis shutdown, minimizing network downtime and operational disruption.
