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, 3000 W HVDC, 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.S9312 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 and 3000 W HVDC power modules can be used as PoE power modules only in V200R012C00 and later versions.
    • The S9303 provides the maximum available power of 3000 W, and the S9306 as well as S9312 provide the maximum available power of 9000 W.
  • S9306 and S9312 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. S9303 supports only one PoE power supply slot. The PoE power supply cannot work in redundancy mode.

  • 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.

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.

Restrictions on the PoE function
  • Currently, the switch supports only one type of PoE board, that is, LE0DG48VEA00.
  • 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.
