ES1D2X32SX2E FAQ
Q1: Is this line board compatible with Huawei S9306 switches? Will there be a bandwidth bottleneck when all 32 ports are running at full load simultaneously?
A1: Fully compatible! Supports the entire S9300 series of switches, with a backplane bandwidth ≥320Gbps. There is no bottleneck when all 32 ports are simultaneously operating at full load (320Gbps total bandwidth), fully meeting the needs of medium-scale high-density access.
Q2: How stable is the transmission over a 55m distance when using Cat.5e copper cable to connect monitoring equipment? Is it interference resistant?
A2: Extremely stable! Cat.5e copper cable can stably transmit at 10GE rates within 55m, with electromagnetic interference resistance meeting EMC Class A standards. There is no packet loss or latency fluctuation, suitable for various devices such as monitoring equipment, servers, and terminals.
Q3: What are the core differences between this and the Huawei 32-port 10 Gigabit optical mid-range line board (ES1D2X32SX2S)? How to choose?
A3: The core difference lies in the transmission medium and scenario: ES1D2X32SX2E (electronic port + copper cable, ≤100m) is suitable for short-distance, medium-scale scenarios within a data center using multiplexed copper cables; the optical port version (fiber optic, 300m-40km) is suitable for long-distance interconnection. Choose the copper cable version for short-distance connections within a data center, and choose the optical port version for cross-data center/long-distance connections.
