1. Introduction
Using a Power over Ethernet (PoE) Layer 2 switch, IP telephones are supplied power
over the last pair of CAT-5 cable that connects them to the switch. This eliminates the
need for a separate power supply to power the telephone. For this to work, the port the
telephone is connected to must support Power over Ethernet or have a power adapter
placed in series between the switch port and the telephone. The Layer 2 switches are
Power Sourcing Equipment (PSE) and comply with the IEEE 802.3af standard protocol.
The telephones are Powered Devices (PD) that also comply with the IEEE 802.3af
standard protocol.
The Samsung Ubigate
TM
iBG-3026 is one such PSE capable of providing Power over
Ethernet using a blade module. The LMP20 blade module has 20 10/100 Base-T Ethernet
ports and plugs into one of the 2 slots available in the Samsung Ubigate
TM
iBG-3026
Integrated Services Router. The following inline power capable Avaya IP Telephone
Devices are directly connected to the Samsung Ubigate
TM
iBG-3026 to receive inline
power as shown in Figure 1.
• Avaya 4600 series IP Telephone
o 4602SW IP Telephone
o 4610SW IP Telephone
o 4620SW/4621SW/4622SW IP Telephone
o 4625SW IP Telephone
• Avaya 9600 series IP Telephone
o 9620 One-X Deskphone
o 9630 One-X Deskphone
Note that the 4620SW IP Telephone comes in either as a Class 2 and Class 3 power
device. The Class 2 telephone has one microphone hole at the bottom right side of the
telephone while the Class 3 has two holes.
The Institute of Electrical and Electronics Engineers (IEEE) 802.3af classifications
classifies the powered devices such as the Avaya IP Telephones. The power the switch
supplies to the PD depends on the PD’s class (The IEEE 802.3af PSE and Powered-
Device Power Classifications chart can be seen in the Table 3).

4. IEEE 802.3af PoE Implementation on the Avaya IP
Telephones and Samsung Ubigate
TM
iBG-3026.
Table 2 lists the detected IEEE 802.3af class and measured power of the Avaya
IP Telephones when connected to the iBG LMP20 PoE blade. The power
readings listed in Table 2 were measured by the iBG-3026 when the telephones
were idle. Cable length and impedance affects power usage, so the measurements
listed may vary based on the cable used.
The IEEE 802.3af classifications for the PDs are given in Table 3. Note that Class
0 and Class 3 are identical. The reason for this is that Class 0 covers the case
where a powered device is detected but the PSE cannot assign the powered device
to Classes 1, 2, or 3.

5. Configuring and Verifying Inline Power on the Samsung
Ubigate
TM
iBG-3026
The Samsung Ubigate
TM
iBG-3026 Integrated Services Router provides three
kinds of power; they are the AC power, AC with PoE power, and DC with PoE
power. Any combination of the three kinds of power can be mounted to any of the
2 power module slots available. Dual AC with PoE Power supplies are
recommended for power supply redundancy. In the test configuration only AC
with PoE power was mounted and used for testing.
The Samsung Ubigate
TM
iBG-3026 ISR configuration interface can be accessed
through a Microsoft
TM
Windows HyperTerminal. To access the router, the
computer needs to be connected to the router’s console port located in the back
with the serial cable provided. Alternatively, use remote connection such as telnet
to configure the system.
To access the PoE commands, access the config mode and access the next level of
poe commands by typing “poe”.

The real time power consumption can be displayed using the command “show poe
portmeasurements x y” on the Ethernet interface configurations mode. The x
indicates the slot and the y indicates the logical position of the port. The LMP-20
PoE board has 20 logical position numbered from 0-19. The power limit is shown
by using the command “show poe portstatus x y” whether there is overload,
underload or force on current. In order to show the power consumption of the
PoE blade at one glance, you use the command “show poe portspower x”. Below
are some of the commands which are useful for setting or showing the PoE
