Redundant Uplink with Switch Mode
When configured for Uplink Redundant Mode “return to primary’, a fault on the
primary Port F1, will cause a fail over to the secondary Port F2 within 50msec.
The module will return to the primary Port F1 after the failure condition has been
restored for 6 seconds.
SW5: MAC Learning - “MAC Learning/Off”
When this DIP-switch is in the DOWN “MAC Learning” position (factory default), all
ports on the module will learn the source MAC address of each received packet and
store the address so packets destined for the stored addresses can be forwarded to
the appropriate port on the module. When the DIP-switch is in the UP “Off” position,
learning is turned off and all received unicast packets are forwarded to all ports.
SW6: Forced PoE - “Off/ PoE Forced”
This DIP-switch allows the PoE power to be forced ON when connected to a PD
with non-standard detection characteristics. The DIP-switch controls the forced
capability for the RJ-45 user ports on the module.
When this DIP-switch is in the DOWN “Off” position, all RJ-45 user ports will
automatically perform the detection, classification and powering functions for the
attached PD. When this DIP-switch is in the UP “PoE Forced” position, all RJ-45
user ports will provide a maximum of 60 or 100 watts of power (depending on the
model) to the PD.
SW7: L2CP - “L2CP Tunnel/Discard”
When this DIP-switch is in the DOWN “L2CP Tunnel” position (factory default), all
L2CP frames will be tunneled through the module. When this DIP-switch is in the
UP “Discard” position, all L2CP frames will be discarded.
SW8: PSE Reset - “Off/PoE Reset”
The module can be configured to disable (reset) the PoE output power for 5 seconds
after a loss of receive link on any uplink port. This feature is typically used to allow
a PD to re-initialize after a failure on the incoming uplink.
When this DIP-switch is in the DOWN “Off” position (factory default), PoE output
power does not reset on a loss of receive link on any uplink port. When this DIP-
switch is in the UP “PoE Reset” position, the module will disable PoE output power
for 5 seconds following a loss of receive link on any uplink port.

When uplink redundancy is enabled, the loss of link on either F1 or F2 will not cause
the PD to be re-initialized even though the PSE Reset is enabled. The PD will be
re-initialized on a loss of receive link on both uplink ports.
When Dual Device Mode is enabled, the loss of receive link on a uplink port will
re-initialize the PDs associated with the that uplink port. Ports P1 and P2 will drop
PoE power when a loss of receive link on F1 is detected and ports P3 and P4 will
drop PoE power when a loss of receive link on F2 is detected.
2) Installing the Module
Wall Mounting
The wall mounting height of the module should be less than or equal to 2 meters
(6.6 feet) from the floor. Use the four mounting holes on the module to secure the
module to the wall. The module can accommodate #6 screws (not included).
Installation of the module should be such that the air flow in the front, back, side
and top vents of the switch are not compromised or restricted.
The accessory cables should have their own strain relief and do not pull down on
the module.
Rack Mounting
The module can be rack mounted using the optional Rack Mount Shelf (8260-0).
Refer to the Rack Mount Shelf user manual (040-08260-001x) for the proper
installation guidelines.
Follow the same guidelines above when rack mounting the module.
3) Apply Power
AC Power
Secure the ground wire to the ground screw. See the figure below for the location
of the grounding screws.
Route the power cord through the provided strain relief for additional support and
connect the DIN connector at the end of the wire on the AC/DC adapter to the DIN
connector on the module. Connect the AC/DC adapter to the AC outlet. Confirm
that the module has powered up properly by checking the Power LED located on
the front of the switch.

Make sure to disconnect the power and ground cables before removing the module.
