Chapter 1 Remote Power-Feeding Configuration
1.1 Overview
S3026C-PWR Ethernet Switch provides Power over Ethernet (PoE) function, which
performs remote power-feeding to connected powered devices (PD) such as IP phones,
WLAN APs and Network cameras, by providing -48V DC power to the attached remote
PDs through twisted-pairs.
zAs a kind of power sourcing equipment (PSE), S3026C-PWR complies with the
IEEE802.3af standard. Besides, it can also supply power to
non-802.3af-compliant PDs.
zS3026C-PWR is capable of concurrent data transfer and current transfer through
the signal lines 1, 3, 2 and 6 in category-3/category-5 twisted pairs. Alternatively, it
can also use the signal lines 1, 3, 2 and 6 in category-3/category-5 twisted pairs to
transfer data and use the spare lines 4, 5, 7 and 8 to transfer current. You can opt
for either power supply mode by inputting command lines or pressing the mode
button.
zS3026C-PWR supplies power to outside with 24 fixed Ethernet electrical ports. It
can feed power to up to 24 remotely attached Ethernet switches, traveling a
longest distance of 100m.
zEach Ethernet port can provide a maximum power of 15.4W to the devices
connected to it.
zAn S3026C-PWR as a whole provides a total of 160W at most during remote
power-feeding. It decides whether to feed power to a next remote device
according to the currently available power.
Note:

1.2 Configuring Remote Power-Feeding
An S3026C-PWR can automatically checks up whether a connected device needs a
remote power-feeding and supply power to those in demand.

You can input command lines to enable/disable remote power-feeding on a port, adjust
its power-feeding mode and PD detection mode, and set its power-feeding priority and
ctionality. As such, you can also press the "mode" button to
PDs connected to an S3026C-PWR and allow the
S3026C-PWR to supply power to PDs on spare lines and signal lines simultaneously.
