Feature Limitations

PoE Power Supplies Supported by the Switch
  • A switch supports several types of PoE power modules: 800 W AC, 2200 W AC, 2200 W DC, and 3000 W AC power modules.
    • With 220 V input voltage, 800 W AC and 2200 W AC power modules provide maximum output power of 800 W and 2200 W, respectively. With 110 V input voltage, they provide the maximum output power of 400 W and 1100 W, respectively.S7712 does not support inputting 110 V voltage.
    • 2200 W DC power modules can be used as PoE power modules only in V200R006C00 and later versions.
    • 3000 W AC power modules can be used as PoE power modules only in V200R012C00 and later versions.
    • The S7703 provides the maximum available power of 3000 W, and the S7706 as well as S7712 provide the maximum available power of 9000 W.
  • The S7706 and S7712 provide four PoE power supply slots that can be installed with four PoE power supplies simultaneously. The PoE power supplies can work in redundancy mode. S7703 supports only one PoE power supply slot. The PoE power supply cannot work in redundancy mode.

  • The S7706 PoE and S7703 PoE switches do not have specific PoE power supply slots. As long as a power module is installed in a power module slot, PoE power supply can be implemented after a PoE board ES0D0G48VA00, ES1D2G48VX5S, or ES1D2G48VX5E is installed.
  • The maximum output power of the system is determined by the number, type, and voltage of PoE power supplies. For the maximum PoE power of each switch, see "PoE power modules" in the Hardware Description - Power Supply Slot Configuration.

Restrictions on the PoE function
  • Currently, the switch supports three type of PoE board, that is ES0D0G48VA00, ES1D2G48VX5S, and ES1D2G48VX5E.
  • For an ES1D2G48VX5S or ES1D2G48VX5E board, the following first and second operations will not power off the PDs connected to interfaces on this board, but the third operation will. For an ES0D0G48VA00 board, any of the following three operations will power off these PDs.
    1. Run the reset slot command to reset the board.
    2. Run the reboot command to restart the switch.
    3. Run the power off command to power off the board.
  • For the S7703, S7706, or S7712, a PoE board can provide power to PDs only a chassis has both a PoE power module and PoE board installed. In a CSS, if chassis 1 has a PoE board installed but does not have any PoE power module installed, the PoE board of chassis 1 cannot provide power to PDs even if chassis 2 has a PoE power module installed.
  • If a CMU board fails or is reset on the switch, the PD is powered off.
PoE function
  • The switch supports power supply capability negotiation using the Link Layer Discovery Protocol (LLDP).
  • The switch supports perpetual power supply and fast power-on.
  • If a switch supports PoE, its PoE feature is not affected after it joins a CSS.

  • The maximum PoE power supply distance is 100 m.
