Products Description


CloudEngine S5755-H series multi-GE switches are high-quality gigabit access switches with 24- or 48-port options, offering GE/Multi-GE electrical downlink ports, four 10GE, four 25GE plus two 100GE uplink ports.

By leveraging unified software platform, CloudEngine S5755-H series multi-GE switches create a multi-purpose network through VXLAN-based network virtualization. The series also stands out for free mobility that delivers consistent user experience anywhere, anytime. A maximum of 48 downlink ports and MACsec support on all ports make CloudEngine S5755-H the best choice of access switches for the Wi-Fi 6 and Wi-Fi 7 era. With these merits, CloudEngine S5755-H series can be widely used in healthcare, retail, mining, Internet Service Provider (ISP), and other industries.

Long-term operating temperature [°C(°F)]
–5°C to +45°C (23°F to 113°F) at an altitude of 0 to 1800 m (0 to 5905.44 ft.)
Short-term operating temperature [°C(°F)]
-5°C to +50°C (23°F to 122°F) at an altitude of 0-1800 m (0-5905.44 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 exceeds 45°C (113°F) for no more than 96 consecutive hours in a year.
The total time in which the operating temperature exceeds 45°C (113°F) in a year is less than or equal to 360 hours.
The number of times the operating temperature exceeds 45°C (113°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 device cannot start when the temperature is lower than 0°C (32°F). The maximum transmission distance of an optical module used
for short-term operation cannot exceed 10 km.
When the QSFP-100G-ER4 or QSFP-100G-LR1 optical module is used, the operating temperature ranges from -5°C to +40°C (23°F to
104°F).
Storage temperature [°C(°F)]
–40°C to +70°C (–40°F to +158°F)
Long-term operating relative humidity [RH]
5% RH to 95% RH (non-condensing)
Long-term operating altitude [m(ft.)]
0–5000 m (0–16404 ft.)
Storage altitude [m(ft.)]
0-5000 m (0-16404 ft.)
