Questions & Answers
What is the Cisco FET-10G=?
The Cisco FET-10G= is a 10 Gigabit Ethernet line extender for FEX devices that extends high-speed connectivity up to 10 km over single-mode fiber.
What are the key features of the FET-10G=?
Key features include 10 Gbps full-duplex throughput, up to 10 km reach on single-mode fiber, sub-2 µs latency, hot-swappable SFP+ form factor and seamless integration with Cisco Nexus FEX modules.
What maximum distance does the FET-10G= support?
The FET-10G= supports link extensions up to 10 km (6.2 mi) over single-mode fiber with standard SFP+ optics.
Which type of cabling and connectors are required for the FET-10G=?
The FET-10G= requires single-mode fiber cabling with LC-to-LC SFP+ transceivers for both link and FEX uplink connections.
How do I install the FET-10G= in a Cisco FEX environment?
To install, power down the FEX, insert the FET-10G= module into an available uplink slot, attach SFP+ optics, then power up and verify link status on the parent Nexus switch.
Is the FET-10G= compatible with non-Cisco switches?
No. The FET-10G= is validated exclusively for use with Cisco Nexus FEX modules and requires a Cisco parent switch for full feature support.
What throughput performance can I expect from the FET-10G=?
You can expect full 10 Gbps bidirectional throughput with line-rate forwarding and minimal packet loss when properly provisioned.
Does the FET-10G= support link resilience or redundancy?
Yes. It supports link-level redundancy, auto failover between multiple uplinks, and rapid reconvergence managed by the parent Nexus switch.
Can I monitor and manage the FET-10G= through Cisco DCNM?
Yes. The FET-10G= is fully managed as part of the FEX inventory in Cisco Data Center Network Manager (DCNM) via the upstream Nexus switch.
What are the power requirements for the FET-10G=?
The FET-10G= draws power directly from the FEX module and does not require an external power source.
Does the FET-10G= support QoS or traffic prioritization?
Yes. It transparently carries 802.1p traffic classes and trusts QoS markings configured on the parent Nexus switch for end-to-end prioritization.
What latency does the FET-10G= introduce?
The FET-10G= adds less than 2 microseconds of point-to-point latency, ensuring wire-speed forwarding for time-sensitive applications.
How do I order the FET-10G=?
Order through an authorized Cisco reseller or partner using SKU FET-10G=. Provide the Cisco part number to your sales contact for prompt fulfillment.
