The S series fixed Ethernet switches integrate the access and transmission functions to provide reliable access/aggregation and high-quality transmission of services on enterprise networks. The switches are built on an integrated hardware platform, and their hardware system consists of the chassis, power module, fan module, extended cards, and Switch Control Unit (SCU).
The Huawei S5735-L24T4X-IA1 is a high-performance, cost-effective entry-level 10 Gigabit switch in the Huawei S5735 series. Its core advantage is its "economical and efficient entry-level networking for small and micro enterprises"—24 Gigabit Ethernet ports adapt to 800-1800 terminals, 4 10 Gigabit optical ports support high-speed uplink, and the number of ports is suitable for small and micro enterprises with no idle ports; the total switching capacity is ≥598Gbps, the forwarding performance reaches 96Mpps, and it supports basic full functions such as ACL and QoS. The procurement cost is 25% lower than the advanced models with the same configuration, making it the core choice for small and micro enterprises and branch offices that "balances cost, performance and practicality".
S5735-L24T4X-IA1 FAQ
Q1: What is the core difference between this switch and the advanced model S5735S-L24T4S-A in the same series?
A1: The former is an entry-level, high-performance model (focusing on basic networking for small and micro enterprises, with lower costs), while the latter is an advanced model (focusing on more expansion functions). Small and micro enterprises with limited budgets and no complex expansion needs should prioritize the former.
Q2: Is this switch compatible with existing legacy devices and non-Huawei gateways?
A2: Fully compatible with standard Ethernet protocols and 10/100/1000M adaptive speeds, it can seamlessly connect with gateways from different brands and legacy terminals without requiring reconstruction of the existing network.
Q3: Will there be any lag when all 24 Ethernet ports are connected simultaneously?
A3: No, the total switching capacity is ≥598Gbps, the forwarding performance reaches 96Mpps, it supports 10 Gigabit link aggregation, and the single-link bandwidth can be expanded to 40G, meeting the needs of high-density concurrent transmission of terminals in small and micro enterprises.

Long-term operating temperature [°C(°F)]
–40°C to +65°C (–40°F to +149°F) at an altitude of 0–1800 m (0–5906 ft.)
NOTE:
–40°C to –30°C (–40°F to –22°F): Stable port performance can be achieved only when at least four of the first eight Ethernet electrical ports go Up.
Short-term operating temperature [°C(°F)]
–40°C to +70°C (–40°F to +158°F) at an altitude of 0–1800 m (0–5906 ft.)
Restriction on the operating temperature variation rate [°C(°F)]
When the altitude is 1800-5000 m (5906-16404 ft.), the highest operating temperature reduces by 1°C (1.8°F) every time the altitude increases by 220 m (722 ft.).
The device can work for a short period of time when the operating temperature is beyond the normal range, but the following conditions must be met:
The operating temperature can exceed 65°C (149°F) for a maximum of 96 consecutive hours in a year.
The total time when the operating temperature exceeds 65°C (149°F) in a year is less than or equal to 360 hours.
The number of times the operating temperature exceeds 65°C (149°F) is less than or equal to 15 in one year.
If any of the preceding conditions is not met, the device may be damaged or an unknown error may occur.
The maximum transmission distance of an optical module used for short-term operation cannot exceed 10 km.
