Connecting the 1152B PDU cables
All of the ports on the front of the 1152B PDU are configured as data route-through ports for all
data wires (pins 1, 2, 3 and 6).
Use a standard CAT5, CAT6 or CAT6e straight-through Ethernet cable (not supplied), including
all 8 wires (4 pairs) as shown in
Connecting cables to telephones and other end devices on
page 327.
Figure 28: Connecting telephones and other end devices to the 1152B PDU
For Data-In ports connect the Ethernet cable leading from the Ethernet Switch/Hub to the Data
port. For Data & Power Out ports connect the Ethernet cable leading to the telephone or other
end device to the corresponding Data & Power port.
Note:
Note:
Be certain to connect correspondingly numbered Data and Data & Power ports.
Connecting cables to telephones and other end devices
An 1152B PDU contains line-sensing capabilities that enables it to send power only to end
devices designed to receive power from the LAN. These end devices, termed Power over LAN
Enabled, receive power once they are connected to the 1152B PDU.
To safeguard devices that are not enabled, the 1152B PDU detects devices that are not enabled
so does not send power. Note that data continues to flow using the Ethernet cable regardless of
the status of the end device.
