Connecting to the Network
The following procedures cover the cable connections from the network or other devices to the D2
switch.
• Connecting UTP Cables to RJ45 Ports
• Installing an Optional SFP on page 2‐29
• Connecting Fiber‐Optic Cables to SFP Ports on page 2‐32

Connecting UTP Cables to RJ45 Ports

RJ45 10000BASE‐TX front panel ports on the D2G124‐12 and D2G124‐12P switches support Auto
MDIX, which means that you can use straight‐through or crossover twisted pair cabling.
To connect twisted pair segments to the D2, refer to Figure
follows:
1. Ensure that the device to be connected at the other end of the segment is powered on.
2. Connect the twisted pair segment to the D2 by inserting the RJ45 connector on the twisted pair
segment into the desired RJ45 port.
2-28 Installation
Note: All RJ45 front panel and IOM ports support Category 5 Unshielded Twisted Pair (UTP)
cabling with an impedance between 85 and 111 ohms. Category 3 cable may be used if the
connection is going to be used only for 10 Mbps.
