On the 7705 SAR-H, 7705 SAR-Hc, and 6-port SAR-M Ethernet module, a PoE-capable port
can be configured for PoE and PoE+. On the 7705 SAR-W and 7705 SAR-Wx, a PoE-
capable port only supports PoE+ and can only be enabled using the poe plus command.
On the 7705 SAR-H, before a port can be configured for either PoE or PoE+, the PoE power
source option must first be configured as either internal or external using the
config>system>poe-power-source command; refer to the 7705 SAR Basic System
Configuration Guide, “System Command Reference”, for information.
When the 7705 SAR-H is configured for the internal power source option, PoE capability is
allowed on ports 5 and 6 only. Port 5 can be configured for PoE+ but in that case, port 6
cannot support PoE. When the system is configured for the external power source option, a
mix of PoE and PoE+ is allowed on ports 5, 6, 7, and 8. PoE+ is supported only on ports 5
and 7. Table 26 describes the allowed mix of PoE and PoE+ ports on the 7705 SAR-H.
On the 6-port SAR-M Ethernet module, ports 5 and 6 on the module can each support PoE.
Port 5 can also support PoE+, but if it is configured for PoE+, then port 6 cannot support PoE
power.
On the 7705 SAR-Hc, ports 5 and 6 each support PoE and PoE+. If configured for PoE, both
ports can be used for PoE simultaneously. Both ports are also capable of supporting PoE+
but not simultaneously; if one port is configured for PoE+, the other port can only be
configured for PoE. Ports 5 and 6 can also operate in non-PoE mode.
On the 7705 SAR-W, ports 4 and 5 support PoE+. Both ports can operate in non-PoE+ mode.
On the 7705 SAR-Wx, port 5 (the RJ-45 port labeled PoE) supports PoE+. The port can also
operate in non-PoE+ mode.
To disable PoE/PoE+ on a port and prevent it from delivering power, use the no form of the
command. Performing a shutdown command on the port does not disable PoE/PoE+ on the
port.
