Tx/Rx High Speed Links - ADDER AdderLink Infinity dual User Manual

TX/RX high speed links

ALIF dual units can be either connected directly to each other or via a high speed
network. The connections can be copper-based Gigabit Ethernet as well as Fibre
Channel over Ethernet (FCoE). These can be used in parallel to provide up to 2 Gigabit
connections speeds.
A single System port (Gigabit Ethernet) is provided as standard on the right side of the
front panel. Additionally, the Teaming port, located just to the left, allows you to insert
either an optional Fibre Channel SFP module or Active Copper SFP module. The chosen
module can then allow either a fibre optic or additional Gigabit Ethernet link to be used
in parallel with the fixed System (Gigabit Ethernet) port.
To link ALIF dual units using the Teaming port
1 Insert the appropriate optional SFP module
(SFP-MM-LC, SFP-SM-LC or
SFP-CATX-RJ45) into the aperture on
the ALIF dual front panel:
2 Make your connection(s) between the chosen SFP module and either the other ALIF
dual unit or a suitable network switch:
Connect the transmit and receive
fibre optic links to the sockets on
the Fibre Channel SFP module.
Then close the latch over the link
connectors to lock them into place.
or
Connect a CAT
5, 5e, 6, or 7 cable to the socket on
the Active Copper SFP module.

Please see Appendix C for important tips about networking ALIF units.
To link ALIF dual units using the System port
1 Connect a CAT 5, 5e, 6, or 7 cable to the System port socket on the front panel of the
ALIF dual unit.
CAT 5, 5e, 6, or 7 link either
directly from the other ALIF
unit or from a Gigabit Ethernet
switch
2 Connect the other end of the cable either to the other ALIF dual unit or to a Gigabit
Ethernet switch, as appropriate.
3 [For connections via a network] repeat steps 1 and 2 for the other ALIF dual unit.
Cable and fibre details
• For direct links over Ethernet cable, the length of cable should not exceed 100
metres (328 feet). Network cables used for connections may be category 5, 5e, 6 or
7 twisted-pair cable. ALIF TX units have an autosensing capability on their network
interfaces, so for direct point-to-point connections, no 'crossover' Ethernet cable is
required.
• For direct links via fibre, varying distances can be achieved depending on the module
and cable types used. Please refer to the table in
The fibre links must have crossovers.
