Q1: Is the Huawei CloudEngine S5735-L12T4S-A a fanless switch?
A: Yes, it adopts a fanless design with natural heat dissipation, enabling completely silent operation. This makes it especially suitable for noise-sensitive environments such as libraries, hotel reception areas, and open offices.
Q2: Does the S5735-L12T4S-A support Power over Ethernet (PoE)?
A: No. This model is a data-only switch and does not provide PoE functionality. It is intended for devices with independent power sources. For a PoE version, consider the S5735-L12P4S-A.
Q3: What is the port configuration of this switch?
A: It provides 12 x 10/100/1000Base-T (Gigabit RJ45) downlink ports along with 4 x GE SFP uplink ports for flexible fiber connectivity.
Q4: What is the switching capacity and forwarding performance?
A: The switch delivers a forwarding rate of 24 Mpps, with a device switching capacity of 32 Gbps and an overall system switching capacity of 336 Gbps.
Q5: Can multiple S5735-L12T4S-A switches be stacked?
A: Yes. With Huawei's iStack technology, up to 9 switches can be combined into a single logical device using electrical ports, providing up to 80 Gbps bidirectional stack bandwidth.
Q6: Does this model support Layer 3 routing?
A: Yes. It is a fully managed switch supporting Layer 3 features, including IPv4 static routing, RIP (v1/v2), and OSPF.
Q7: What is the maximum power consumption of the device?
A: Thanks to its efficient fanless architecture, the maximum power consumption is only 29 W, while typical consumption at 30% load is around 23 W.
Q8: What are the physical dimensions and weight?
A: The switch uses a compact 1U chassis measuring 43.6 mm (H) x 442 mm (W) x 220 mm (D), with a total weight of approximately 3.83 kg including packaging.
Q9: What are the CPU and memory specifications?
A: It is powered by a 4-core 1000 MHz CPU, with 1 GB of RAM and 512 MB of flash memory (approximately 306 MB available for users), ensuring stable enterprise performance.
Q10: Does it support USB-based deployment?
A: Yes. A built-in USB 2.0 port allows for zero-touch deployment, batch configuration, and software upgrades via USB storage devices.
Q11: Can the S5735-L12T4S-A be managed via the cloud?
A: Yes. It supports cloud-based management through Huawei platforms such as iMaster NCE-Campus, enabling remote configuration, monitoring, and reduced O&M effort.
Q12: What security features are included?
A: The switch offers enterprise-grade security, including 802.1X authentication, MAC authentication, DHCP snooping, strict ARP learning, and protection against DoS attacks such as SYN flood and ICMP flood.
