CIS - 80MKV ROUTER
PRODUCT MANUAL
8. PoE Information and Settings
PoE - Out Modes:
Auto - on mode
If auto - on is selected on a PoE - Out interface, then the port operates in this strict order:
•
The router checks for resistance on the connected port. If the detected resistance range is between (3k Ω to 26.5k Ω), the
power is turned on.
•
When power is applied, the router continuously checks if the overload limit is reached, or if a short circuit is detected.
•
If the cable is unplugged, the port returns to the detection state, and will remain off until suitable power draw is detected.
Forced - on mode
If forced - on is selected, then the port operates in this strict order:
•
There is no resistance check on the port. The router applies power on pins 4,5 (+) and 7,8 ( - ), even if no cable is attached.
•
When power is applied, the router continuously checks if an overload or a short circuit is detected.
•
After the cable is unplugged, the power still remains enabled on the port.
Off mode
If off mode is used, PoE - Out on the port will be turned off, no detection will take place, and the interface will behave as a sim-
ple Ethernet port.
PoE - Out limitations
It is important to check the PoE - Out specifications for hardware limitations because it can differ between models.
PoE - Out ports are limited with maximum amp values which are supported for a particular voltage. Usually max current will
differ for low voltage devices (up to 30 V), and for high voltage devices (31 to 57 V).
PoE supplying devices also have a total current limitation which can't be exceeded, even if individual port limit allows it.
All CIS equipment uses the same PoE - Out pin polarity Mode B 4,5 (+) and 7,8 ( - ), however other vendors can use opposite o r
Mode A pinout on PD, this requires using a special crossover cable
Enable/Disable PoE on a Specific Port
On the CIS - MK80V, only port 10 is capable of powering devices through PoE. Select port 10 from the Interfaces tab. Change the
PoE Out option accordingly.
