Questions & Answers
What is the ES5D21Q02Q00 2‐port 40 GE QSFP+ interface card?
The ES5D21Q02Q00 is a dual-port 40 Gigabit Ethernet QSFP+ interface card designed for high-density data center and enterprise switch platforms, delivering up to 80 Gbps aggregated throughput.
Which network switches support this 2-port 40 GE QSFP+ card?
This card is compatible with leading 40 GE-enabled switches from major vendors. Consult your switch’s hardware compatibility list to confirm support for SKU ES5D21Q02Q00.
What optics and cables are supported on each QSFP+ port?
Each QSFP+ port accepts 40 GbE SR4/LR4 DACs, AOCs and MTP/MPO transceivers. Supported modules include 40G SR4 (850 nm up to 100 m) and LR4 (1310 nm up to 10 km).
Can I use breakout cables with the ES5D21Q02Q00?
Yes. You can deploy 1×4 breakout cables (4×10 GbE) per QSFP+ port to connect to four separate 10 GbE devices, enabling flexible port utilization.
What is the maximum reach for optical connections?
Using SR4 transceivers, reach is up to 100 m over OM3 multimode fiber. With LR4 optics, single-mode fiber reach extends to 10 km.
How do I install the 2-port 40 GE QSFP+ interface card?
Power down the switch, insert the card into the designated QSFP+ slot, secure the retention screws, then power the system back on. Verify link status via CLI or management GUI.
What power budget does the ES5D21Q02Q00 require?
Each port consumes up to 4 W for DAC/AOC and up to 8 W with LR4 optics. The card’s total power draw does not exceed 20 W under maximum load.
What is the operating temperature range?
The card operates reliably between 0 °C and 40 °C (32 °F to 104 °F) when installed in compatible, well-ventilated chassis.
Does this interface card support jumbo frames?
Yes. The ES5D21Q02Q00 supports jumbo frames up to 9,216 bytes, improving throughput efficiency for large-packet applications.
What latency can I expect from each 40 GE port?
Latency is typically under 300 nanoseconds per port under full load, making it suitable for latency-sensitive workloads.
Is RDMA over Converged Ethernet (RoCE) supported?
Yes. The card supports RoCE v1 and v2 for low-latency, high-throughput storage and HPC applications.
How do I update the interface card firmware?
Download the latest firmware package from your switch vendor’s support site and follow the CLI upgrade procedure. Always back up current settings before updating.
What diagnostic tools are available for troubleshooting?
Built-in diagnostics include link status, loopback tests, SFP-QM reports and per-lane error counters accessible via CLI or SNMP.
What warranty covers the SKU ES5D21Q02Q00?
This card is backed by a limited lifetime warranty, including RMA support and next-business-day advanced replacement, subject to your vendor’s warranty policy.
How do I order replacement QSFP+ modules for this card?
Order using the module vendor’s part numbers for 40G SR4 or LR4 transceivers. Verify compatibility with SKU ES5D21Q02Q00 in your vendor’s ordering guide.
