ERS3626GTS-PWR+ : Low POE power mode (Fanless mode) support
  • ERS3626GTS-PWR+
In Low POE power mode (Fanless mode), the fan speed is reduced to accommodate silent operation for open environments where reduced noise from the fans is required. The surrounding ambient air temperature for use of this feature is required to be 30 degrees Celsius (86 F) or lower. The available PoE budget for the switch when operating in lowpower-budget is limited to 90 Watts in total (802.3af/at) allowing the switch to operate with an acoustic output of 40 db or less.
  • Low PoE power setting is supported on the ERS3626GTS-PWR+ only
  • This feature is supported in stand-alone mode only
1. Enter Global Configuration mode:
