2.5 Making RJ-45 Copper Port Connection
The balanced twisted-pair copper (TP) port supports the following connection types and distances:
Network Cables
10GBASE-T: 4-pair UTP Cat. 6a or better, EIA/TIA-568B 100-ohm
5GBAST-T: 4-pair UTP Cat. 6 or better, EIA/TIA-568B 100-ohm
2.5GBAST-T: 4-pair UTP Cat. 5e or better, EIA/TIA-568B 100-ohm
1000BASE-T: 4-pair UTP Cat. 5 or better (Cat.5e is recommended), EIA/TIA-568B 100-ohm
Link distance: Up to 100 meters
Auto MDI/MDI-X Function
This function allows the port to auto-detect the twisted-pair signals and adapts itself to form a valid MDI to
MDI-X connection with the remote connected device automatically. No matter a straight through cable or
crossover cable is connected, the ports can sense the receiving pair automatically and configure itself to match
the rule for MDI to MDI-X connection. It simplifies the cable installation.
Auto-negotiation Function
The port is featured with auto-negotiation function and full capability to support connection to any Ethernet
devices. The port performs a negotiation process for the speed and duplex configuration with the connected
device automatically when each time a link is being established. If the connected device is also
auto-negotiation capable, both devices will come out the best configuration after negotiation process. If the
connected device is incapable in auto-negotiation, the port will sense the speed and use half duplex for the
connection.
Conversion Line Rate
After auto-negotiation, the negotiated speed is as the line rate for conversion between RJ-45 copper port and
SFP+ fiber port.
2.6 Making SFP+ Fiber Connection
The fiber port is equipped with one SFP+ slot that can be installed with a matched fiber transceiver in order to
support different line rates of fiber connectivity. Your device unit may come with an SFP transceiver
pre-installed when it was delivered.
Installing SFP Fiber Transceiver
To install an SFP fiber transceiver into an SFP slot, the steps are:
1. Turn off the power to the device unit.

-14-
2. Insert the SFP fiber transceiver into the SFP slot. Normally, a bail is provided for every SFP transceiver.
Hold the bail and make insertion.
3. Until the SFP transceiver is seated securely in the slot, place the bail in lock position.
Connecting Fiber Cables
LC connectors are commonly equipped on most SFP transceiver modules. Identify TX and RX connector
before making cable connection. The following figure illustrates a connection example between two fiber
ports:
Make sure the RX-to-TX connection rule is followed on the both ends of the fiber cable.
Network Cables
Multimode (MMF) - 50/125m, 62.5/125m
Single mode (SMF) - 9/125m
Fiber Port Configuration
According to the speed negotiated by the copper port with the connected partner, the SFP+ fiber port uses the
same speed as the operating line rate for packet forwarding between copper port and fiber port automatically.

2.7 Making SFP+ DAC/AOC Connection
The SFP+ lot can also support short reach connections with DAC cable or AOC cables between two converters.
Direct Attach Cable (DAC)
DAC cables are made from copper and are factory terminated copper/twinax cables. DAC cables are used to
connect switches, routers and servers. They’re assembled from shielded copper cables with a fixed length and
are fitted with transceivers on either end of the cable with gauges attached. These can be from 24 up to 30
AWG, while 15 meters of interconnection is possible via the copper cable. There are passive and active types
of DAC cables. Active copper wires use electronics to connect via the connections and transmissions are made
via the copper ends. To put it simply, passive DAC cables do not contain any components that are electrical,
minimizing power usage. Active cables benefit from boosted signals and use more power but ensure better
quality transmissions.
The SFP+ Passive DAC cable is a high-performance, cost effective solutions for 10Gb Ethernet and 10G Fiber
Channel applications. SFP+ Passive DAC cable enables hardware manufacturers and data center operators to
achieve high port density, configurability and utilization at a very low cost and with reduced power
requirements.

-16-
Active Optical Cable (AOC)
AOC is one of the forms of DAC cable. It integrates multimode optical fiber, fiber optic transceivers, and
modules. AOCs have many benefits such as lighter weight, high performance, low power consumption, low
interconnection loss, EMI immunity, and flexibility etc. Primarily, active optical cable (AOC) assemblies were
invented to replace copper technology in data centers and high performance computing (HPC) applications. As
we know, copper passive twinax cable is heavy and bulky, making it difficult to physically manage the
datacenter. And due to the nature of electrical signals, electromagnetic interference (EMI) limits copper’s
performance and reliability.

2.8 Making Management Connection
The device is featured to support web-based management and SNMP management. Use Cat.5 cable and
connect the management port to a TCP/IP network where the web management host and SNMP host are
located. The following figure illustrates a typical connection:

management:
Default IP address of the device: 192.168.0.2 / 255.255.255.0
Default Password of the device: 123
The IP Address is an identification of the device unit in a TCP/IP network. Each unit should be designated a
new and unique IP address in the network. Refer to Web management interface for System Configuration. The
password is used for authentication in accessing to the device via web-based interface. For security reason, it is
recommended to change the default settings for the device unit before deploying it to your network. Refer to
Web management interface for System Configuration.

-20-
2.12 Converter Function
The device supports the following media conversions between fiber cable and Unshielded Twisted-pair (UTP)
(copper) cable:
Operation Rules:
1. Under “Auto”port configuration mode, the conversion line rate depends on the link speed finally
established with the link partner on the RJ-45 copper port. Otherwise, a fixed line rate among 5Gbps,
2.5Gbps, and 1000Mbps is applied for the device.
2. The packet forwarding, data conversion between the fiber segment and UTP segment is transparent. There
is no packet modification in forwarding.
3. No packet type is limited in packet forwarding. The types include untagged packets, tagged packets, BPDU
packets, and the reserved MAC control packets.
4. RJ-45 copper port link down will cause fiber port link down, but not vice versa.
