Question 1

What is the E8KE-X-101-1X40GE-CFP flexible card?

Accepted Answer

The E8KE-X-101-1X40GE-CFP is a 1-port, 40GBase LAN CFP flexible card (P101, ½-width) that occupies two sub-slots. It enables high-speed 40 Gbps uplinks in compatible network chassis.

Question 2

Which Cisco chassis support this 40GBase LAN CFP card?

Accepted Answer

This CFP card is compatible with Cisco modular switches and routers that support P101 flexible cards and allocate two adjacent sub-slots. Check your device datasheet for P101 slot availability.

Question 3

How do I install the E8KE-X-101-1X40GE-CFP card?

Accepted Answer

Power down the chassis, open the faceplate, slide the CFP card into two free P101 sub-slots, secure the captive screws, and power the system back on. The device will auto-detect the new port.

Question 4

Does the card require a software license?

Accepted Answer

No additional license is needed. The E8KE-X-101-1X40GE-CFP operates under your existing LAN Base or IP Services software package.

Question 5

What CFP optical modules can I use with this card?

Accepted Answer

You can use any compliant CFP-MPO or CFP-SR4 optical transceiver supporting 40GBase-LR4 or 40GBase-SR4. Ensure the transceiver matches your fiber type and distance requirements.

Question 6

What fiber types and maximum reach does this CFP card support?

Accepted Answer

With 40GBase-LR4 CFP modules, you get single-mode reach up to 10 km; with 40GBase-SR4 multimode modules, you achieve up to 100 m on OM3 and 150 m on OM4 fiber.

Question 7

What is the power consumption of the 40GBase LAN CFP card?

Accepted Answer

Typical power draw is 15 W per CFP port under standard conditions. Refer to your chassis power budget to confirm availability.

Question 8

What operating temperature and environmental conditions are supported?

Accepted Answer

The card is rated for 0 °C to 40 °C ambient temperature, 5%–85% non-condensing humidity, and standard seismic requirements per NEBS Level 3.

Question 9

Can I mix this CFP card with other port modules?

Accepted Answer

Yes. As long as you install it in two adjacent P101 sub-slots, it coexists with other flexible cards, line cards, or supervisor modules in the same chassis.

Question 10

What data throughput performance can I expect?

Accepted Answer

You get full wire-speed 40 Gbps forwarding, low latency under 1 µs, and line-rate performance with no oversubscription on the CFP port.

Question 11

Which network features are supported on the CFP port?

Accepted Answer

The port supports QoS, jumbo frames up to 9216 bytes, Link Aggregation Control Protocol (LACP), and all standard Layer 2 and Layer 3 switching and routing features.

Question 12

Does the card offer built-in diagnostics?

Accepted Answer

Yes. The CFP interface supports real-time optical monitoring for transmit/receive power, temperature, and laser bias current via Digital Optical Monitoring (DOM).

Question 13

How do I troubleshoot link issues on the CFP port?

Accepted Answer

Use the switch’s show interface transceiver and show logging commands to check optical diagnostics and log messages. Verify fiber polarity, cleanliness, and module compatibility.

Question 14

What are the physical dimensions and slot requirements?

Accepted Answer

The ½-width CFP card measures 142 mm × 35 mm and occupies two adjacent P101 sub-slots in the chassis. No additional faceplate clearance is required.

Question 15

What warranty and support options are available?

Accepted Answer

Cisco provides a limited lifetime warranty and access to software updates, online troubleshooting guides, and 24×7 TAC support under your service contract.

Question 16

How do I order the E8KE-X-101-1X40GE-CFP card?

Accepted Answer

You can purchase through authorized Cisco resellers or the Cisco Commerce Workspace using SKU E8KE-X-101-1X40GE-CFP. Contact your partner for pricing and lead times.
