Power management modes
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 58.
NOTE:
•
The PoE+ functionality is available from Junos OS Release 10.2 or later.
•
The PoE+ functionality is available only if your gateway is using 54V power
supply. You can order the 54V powersupply from Juniper Networks.Contact
yourJuniper Networkscustomer servicerepresentative 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 15 on page 30 lists the classes and their power ratings as specified by the IEEE
802.3 AF standard.
