WITCH

The Switch provides 24 front panel RJ-45 ports that 
support the IEEE 802.3af Power-over-Ethernet (PoE) 
standard. Any 802.3af compliant device attached to a 
port can directly draw power from the switch over the 
Ethernet cable without requiring its own separate power 
source. This capability gives network administrators 
centralized power control for devices such as IP phones 
and wireless access points, which translates into greater 
network availability. 

The 2 Gigabit combo ports support fiber Gigabit 
Ethernet short-wave (SX) and long-wave (LX) SFP 
transceivers in any combination. This offers you the 
flexibility of using SFP transceivers to provide 
connectivity between the Switch and a 1000 Mbps core 
network. 

When an SFP port is in operation, the corresponding 
1000BASE-T port is disabled. The 1000 Mbps 
connections can only operate in full duplex mode.

Figure 1 shows the front and rear panels of the Switch. 
The numbers in this diagram refer to numbered sections 
in “Front Panel” on page 10 and “Rear Panel” on 
page 13.

The front panel of the Switch contains a series of 
indicator lights (LEDs) that help describe the state of 
various networking and connection operations.
