One PNP button

To restore the factory settings and reset the switch, hold down the button for at least 6 seconds.

To reset the switch, press the button.

Resetting the switch will cause service interruption. Exercise caution when you press the PNP button.

A 1GE/10GE/25GE SFP28 optical port sends and receives service data at 1 Gbit/s, 10 Gbit/s, or 25 Gbit/s.

When a 25GE optical module is connected to a port, the port can automatically adjust its rate to 25 Gbit/s.

When a 10GE optical module is connected to a port, the port can automatically adjust its rate to 10 Gbit/s.

Before installing a GE optical module or GE copper module on a port, run the port mode ge command to configure the port to work at 1 Gbit/s.

• GE eSFP optical modules

• GE-CWDM eSFP optical modules

• GE-DWDM eSFP optical modules

• GE SFP copper module

• 10GE SFP+ optical modules (OSXD22N00 and SFP-10G-ZR not supported)

• 10GE SFP+ copper module (supported in V200R023C10 and later versions)

• 25GE SFP28 optical modules

• 1 m, 2 m, 3 m, 5 m, and 10 m SFP+ high-speed copper cables

• 3 m and 10 m SFP+ AOC cables

• 1 m SFP28 high-speed copper cable

• 3 m, 5 m, 7 m, and 10 m SFP28 AOC cables

A 40GE/100GE QSFP28 optical port sends and receives service traffic at 40 Gbit/s or 100 Gbit/s.

A QSFP28 optical port cannot be split into four 10GE ports, regardless of whether the port uses a QSFP28 or QSFP+ optical module.

• 40GE QSFP+ optical modules

• 100GE QSFP28 optical modules

• 1 m, 3 m, and 5 m QSFP+ to QSFP+ high-speed copper cables

• 10 m QSFP+ to QSFP+ AOC cable

• 10 m QSFP28 to QSFP28 AOC cable

• 2 m QSFP28 dedicated stack cable (supported in V200R020C10 and later versions)

Console cable

You can connect a switch to a configuration terminal or network management workstation through the ETH management port to configure the switch locally or remotely.

You can choose to download the software package through the ETH management port in the BootLoad menu. File transfer through the ETH management port is faster than transfer through the console port.

Ethernet cable

The USB port can have a USB flash drive connected to upgrade the switch, or transfer configuration files or other files. The USB port can only connect to a USB flash drive that complies with USB 2.0.

USB flash drives from different vendors differ in model compatibility and drivers. If a USB flash drive cannot be used, try to replace it with another one from a mainstream vendor. Switches support a maximum of 128 GB USB flash drives.

USB flash drive

Basic dimensions (excluding the parts protruding from the body): 43.6 mm x 442.0 mm x 220.0 mm (1.72 in. x 17.4 in. x 8.66 in.)

Maximum dimensions (the depth is the distance from ports on the front panel to the parts protruding from the rear panel): 43.6 mm x 442.0 mm x 231.0 mm (1.72 in. x 17.40 in. x 9.09 in.)

1+1

Pluggable AC and DC power modules can be used together in the same switch.

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 cannot start when the temperature is lower than 0°C (32°F).

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).
