HARDWARE FEATURES
POWER SUPPLY CONFIGURATION AND REDUNDANCY:
The S6700 Series supports a highly flexible 1+1 power redundancy architecture. The chassis contains two power module slots (Power Module Slot 1 and Power Module Slot 2), allowing for the installation of a single power module for basic operation or dual power modules for active/standby redundancy . This ensures that the switch remains operational even in the event of a single power supply failure, maximizing network uptime.
AC and DC Power Module Mixing: The S6700 Series supports the simultaneous use of AC and DC power modules in the same chassis starting from software version V200R005C00, offering maximum flexibility for power infrastructure integration .
THERMAL MANAGEMENT AND COOLING:
The S6700 Series employs a forced-air cooling architecture, utilizing two pluggable fan modules located on the rear panel . The airflow design, which draws cool air from the sides and exhausts hot air from the rear, is optimized for high-density rack deployments, ensuring critical components remain within operational temperature thresholds under full load. The fan modules are hot-swappable, enabling replacement without service interruption.

ADDITIONAL INSTALLATION NOTES:
Cabinet/Rack Mounting: The S6700 Series switches are installed in a standard 19-inch cabinet or rack. For switches of this depth and weight, Huawei recommends using guide rails (purchased separately) to support the chassis and ensure safe, secure mounting. The provided front mounting brackets are used to secure the switch to the mounting rails .
ESD Protection: An ESD jack is provided on the front panel. Before installing or maintaining the switch, it is mandatory to wear an ESD wrist strap and insert the other end into this ESD jack to prevent electrostatic discharge damage to sensitive components .
Stacking: The S6700 Series supports service port stacking, allowing multiple switches to be interconnected as a single logical device. Any of the 10GE SFP+ ports can be configured as stack ports, with a maximum of eight physical ports per switch. This feature simplifies management and scales network capacity .
