Web Interface
To set the overall PoE power budget for switch:
1. Click Administration, PoE, PSE.
2. Select Configure Global from the Step list.
3. Set the maximum PoE power provided by the switch, enable the compatible
mode, and set the maximum allocation mode if required.
4. Click Apply.
Figure 216: Setting the Switch’s PoE Budget
Note:
This page shows the maximum PoE power for the ECS2100-10P because the
same source code is used for all of the switches in this series. However, note that the
actual maximum setting for each PoE switch model differs.
Setting the Port
PoE Power Budget
Use the Administration > PoE > PSE page to set the maximum power provided to a
port.
Command Usage
This switch supports both the IEEE 802.3af PoE and IEEE 802.3at-2009 PoE Plus
standards. To ensure that the correct power is supplied to powered devices
(PD) compliant with these standards, the first detection pulse from the switch is
based on 802.3af to which the 802.3af PDs will respond normally. It then sends
a second PoE Plus pulse that causes an 802.3at PD to respond as a Class 4
device and draw Class 4 current. Afterwards, the switch exchanges information
with the PD such as duty-cycle, peak and average power needs.
The number of ports which can supply maximum power simultaneously to
connected devices is listed in the following table. In this table, EPS refers to the
optional external power supply.
