• PoE power modules.
A switch that supports PoE
The S7502E, S7503E, S7503E-S, S7506E, S7506E-V, or S7510E switch.
PSEs
All cards require a PoE dual in-line memory module (DIMM) to provide the PoE function, except the
LSQ3GV48SC0 (LSQM3GV48SC0), LSQ1GV48SD0 (LSQM1GV48SD0), and LSQM4GV48SC0. PoE
DIMMs include the following types:
• 24-port PoE DIMM LSQM1POEDIMMS0.
• PoE master/subordinate DIMM LSBM1POEDIMMH.
For the compatibility between the two types of DIMMs and cards, see Table 9 . For the installation of a
PoE DIMM, see " Installing a PoE DIMM ."

NOTE:
•
The model of a card is LSQM-prefixed on the card package and LSQ-prefixed on the card panel. For
example, LSQ1GV48SD0 and LSQM1GV48SD0 identify the same card.
• Make sure the total PoE power required by all PDs connected to a PSE is not greater than the maximum
PSE power. For more information about the maximum PSE power, see "Appendix A Chassis views and
technical specifications."
An external PoE power supply
An external PoE power supply is required only for the S7502E and S7503E-S switches because the two
models use non-PoE power modules (PSR650-A/PSR650-D/PSR320-A/PSR320-D). The external PoE
power supply must meet the following requirements:
• Output voltage—–46 to –57 VDC for type 1 PoE mode and –52 to –57 VDC for type 2 PoE mode.
• Maximum output current—40 A.
