PoE Configuration
To display the Advanced PoE Configuration page, click System > Services > PoE > Advanced > PoE Configuration. A screen similar to the following displays.
1. The Unit Selection field displays the current PoE unit. To change the PoE unit, select
Field Description
Units Displays the Current PoE Unit. You can change the
PoE Unit by selecting another unit ID listed here. Firmware Version Version of the PoE controller's FW image.
Power Status Indicates the power status.
Total Power (Main AC) Displays the total power provided by the main ac power source.
Total Power (RPS)
Total Power (PD) for GSM5212P switches only
Displays the total power provided by the redundant power source.
Power Source Current source of system power (Main AC or RPS).
Threshold Power System can powerup one port, if consumed power is less than this power. i.e. Consumed power can be between Nominal & Threshold Power values. The threshold power value is effected by changing System Usage Threshold.
Consumed Power Total amount of a power which is currently being delivered to all ports.
2. To set the System Usage Threshold, enter a number from 1 to 99. This sets the threshold
level at which a trap is sent if consumed power is greater than the threshold power.
3. The Power Management Mode describes or controls the power management algorithm
used by the PSE to deliver power to the requesting PDs. Select Static to indicate that the power allocated for each port depends on the type of power threshold configured on the port. Select Dynamic to indicate that the power consumption on each port is measured and calculated in real-time.
4. To set the Auto Reset Mode, select Enable to reset the PSE pot without administrator
intervention whenever a fault condition occurs. Select Disable to allow only the administrator to reset the PSE port whenever a fault condition is detected.
5. To set the traps, select Enable to activate the PoE traps. Select Disable to deactivate the
PoE traps. The default setting is enabled.
6. Click APPLY to send the updated configuration to the switch. Configuration changes take
effect immediately.
PoE Port Configuration
To display the Advanced PoE Port Configuration page, click System > Services > PoE > Advanced > PoE Port Configuration. A screen similar to the following displays.
1. Select the Admin Mode (Enable or Disable) to determine the ability of the port to
deliver power.
2. Port Priority is used to determine which ports can deliver power when the total power
delivered by the system crosses a specific threshold. If the switch is not be able to supply power to all connected devices, priority is used to determine which ports can supply power. The lowest numbered port which is one of the ports of the same priority will have a higher priority. Select the priority order from the following list:
• Low - Low priority
• Medium - Medium priority • High - High priority • Critical - Critical priority
3. Select the High Power Mode from the following options:
• Disabled indicates that a port is powered in the IEEE 802.3af mode.
• Legacy indicates that a port is powered using high-inrush current, used by legacy
PD's whose power requirements are more than 15W from powerup.
• Pre-802.3at indicates a port is powered in the IEEE 802.3af mode initially and then
switched to the high-power IEEE 802.3at mode before 75 msec. This mode needs to be selected if the PD is NOT performing Layer 2 Classification or the PSE is
performing 2-Event Layer 1 Classification.
• 802.3at indicates that a port is powered in the IEEE 802.3at mode. For example, if the
class detected by PSE is not class4, then the PSE port will not power up the PD.
4. The Power Limit Type describes or controls the maximum power that a port can deliver.
Select the type from the following list:
• Class indicates that the port power limit is equal to the class of the PD attached. • User indicates that the port power limit is equal to the value specified by Power Limit. • None indicates that the port will draw up to class 0 max power in case of low power
mode and up to class 4 max power in case of high power mode.
5. Select the Power Limit to define the maximum power (in watts) which can be delivered by
6. The Detection Type Describes a PD detection mechanism performed by the PSE port. • pre-ieee - Only legacy detection is done.
• ieee - 4 Point Resistive Detection is done.
• auto - 4 Point Resistive Detection followed by Legacy Detection is done.
• 4point and Legacy indicates that the resistive 4 point detection scheme is used and when it fails to detect a connected PD, legacy capacitive detection is used.
7. The Timer Schedule defines the timer schedule assigned to the port. Select None to remove the timer schedule assignment.
8. Click Reset to forcibly resets the PSE port.
9. Click CANCEL to cancel the configuration on the screen. This will also reset the data on the screen to the latest value of the switch.
10. Click APPLY to send the updated configuration to the switch. Configuration changes take effect immediately.
The following table describes the PoE Configuration non-configurable fields.
Field Description
Port The interface for which data is to be displayed or
configured.
High Power Enabled when particular port supports High Power
Mode.
Max Power The maximum power in Watts that can be provided
by the port.
Class The Class defines the range of power a PD is
drawing from the system. Class definitions: 0 - 0.44-12.95(watts)
1 - 0.44-3.83(watts) 2 - 0.44-6.48(watts) 3 - 0.44-12.95(watts) 4 - 0.44-25.5(watts)
Output Voltage Current voltage being delivered to device in volts.
Output Current Current being delivered to device in mA.
