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 LEFT “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 RIGHT “Off”
position, learning is turned off and all received unicast packets are forwarded to
all ports.
SW6: Pause - “Pause Off/On”
Setting the DIP-switch to the LEFT “Pause Off” position (factory default) configures
the module to advertise no Pause capability on all ports. Setting this DIP-switch
to the RIGHT “On” position configures the module to advertise Symmetrical and
Asymmetrical Pause capability to all ports.
SW7: L2CP - “L2CP Tunnel/Discard”
When this DIP-switch is in the LEFT “L2CP Tunnel” position (factory default), all
L2CP frames will be tunneled through the module. When this DIP-switch is in the
RIGHT “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 LEFT “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 RIGHT “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 that uplink port. On models with 4 RJ-45 user
ports, 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. On models with 8 RJ-45 user ports, P1 - P4 will drop PoE power
when a loss of receive link on F1 is detected and ports P5 - P8 will drop PoE power
when a loss of receive link on F2 is detected.

2) Installing the Module
The module can be wall or rack mounted using the optional Wall Mount Plate
(8260-3). Refer to the Wall Mount Plate user manual (040-08260-301x) for the
proper installation guidelines.
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 DC Power
This module is intended for installation in restricted access areas. (“Les matériels
sont destinés à être installés dans des EMPLACEMENTS À ACCÈS RESTREINT”).
A restricted access area can be accessed only through the use of a special key, or
other means of security.
The over current protection for connection with centralized DC shall be provided in
the building installation, and shall be a UL listed circuit breaker rated 20 Amps, and
installed per the National Electrical Code, ANSI/NFPA-70.
The 6 Port /Si re48 to +57VDC inclusive of tolerance (2.33A
@ 56VDC max rated power). The 10 Port /Si re46 to +57VDC
inclusive of tolerance (4.49A @ 56VDC max rated power). See specification table
for specific model requirements.
Appropriate overloading protection should be provided on the DC power source
outlets utilized.

WARNING:
Only a DC power source that complies with
safety extra low voltage (SELV) requirements can be
connected to the DC-input power supply.
