PSEs
All modules require a PoE dual in-line memory module (DIMM) to provide the PoE function, except
the LSQ3GV48SC0 (JG663A, JG664A), LSQ1GV48SD0 (JD229B, JC712A), and LSQM1GV48SE0
(JH213A, JH221A). PoE DIMMs include the following types:
•
24-port PoE DIMM LSQM1POEDIMMS0(JC671A).
•
PoE master/subordinate DIMM LSBM1POEDIMMH(JD192B).
For the compatibility between the two types of DIMMs and modules, see
. For the installation
of a PoE DIMM, see "Installing a PoE DIMM."

NOTE:
•
The model of a module is LSQM-prefixed on the module package and LSQ-prefixed on the module panel.
For example, LSQ1GV48SD0 and LSQM1GV48SD0 identify the same module.
•
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 7502 and 7503-S switches because the two
models use non-PoE power supplies (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.
For how to connect an external PoE power supply, see "
Connecting an external PoE power supply
PoE power supplies
PoE power supplies are required only for the 7503, 7506, 7506-V, and 7510.
