Hi, 

Both are the POE terms in the switching.

Short Counter — Number of times there has been a power shortage.

Denied Counter — Number of times the powered device has been denied power.

I understand that "denied power" happens when the power consumed by all my PD loads is more than the power that the switch can supply.

Similarly, what causes Short counter ? What does "power shortage" mean ?

Power over Ethernet (PoE) allows a switch to provide power to connected devices via the same Ethernet cable that transmits data. This eliminates the need for a separate power cord to power devices such as IP phones and wireless access points.

The objective of this document is to show the user how to configure the PoE settings on a 200/300 Series Managed Switch.

• Short Counter — Number of times there has been a power shortage.

• Denied Counter — Number of times the powered device has been denied power.
