The IEEE 802.3 AF (PoE) functionality is supported on SRX210 Services Gateway PoE models that have power supply of 48V. The IEEE802.3 AT (PoE+) functionality is supported on SRX210 Services Gateway PoE models that have power supply of 54V. For more information, see “Adjusting the Power Supply Adapter Tray for the SRX210 Services Gateway for Rack-Mount Installation” on page 70.

NOTE:

The PoE+ functionality is available from JUNOS Software Release 10.2 or later.

The PoE+ functionality is available only if your gateway is using 54V power supply. You can order the 54V power supply from Juniper Networks. Contact your Juniper Networks customer service representative for more information.

PoE Classes and Power Ratings

A powered device is classified based on the maximum power that it draws across all input voltages and operational modes. When the class-based power management mode is configured on the services gateway, power is allocated by taking into account the maximum power ratings defined for the different classes of devices.

Table 18 on page 37 lists the classes and their power ratings as specified by the IEEE 802.3 AF standard.
