Connect to the Data Ports
Depending on the model, your switch can have the following ports:
12-port 10/100/1000BASE-T(12 x 90W) PoE
EX78934X-0VB
+ 4-port 1G/10G SFP+
12-port 10/100/1000BASE-T(12 x 90W) PoE
EX78934X-0VB-CC
+ 4-port 1G/10G SFP+
10/100/1000BASE-TX (PoE) Ports
Ports that support Power over Ethernet provide power to networked devices such
as IP Phones, Wireless LAN Access Points, and IP security cameras with a power
budget of 360 Watts.
PoE 90W Limitation
When using PoE ports at 90 Watts, use PoE ports – 1, 4, 8, and 9 for 90W PoE. See
example below:
1G/10G SFP Ports
SFP transceivers can be installed directly into SFP slots. Ensure that the same type
of transceiver is used at both ends of the link and that the correct type of fiber
cable is used.
