Ethernet Cable Specifications
You must supply the Ethernet cable for connecting workstations or other 10BaseT devices, such as
compatible hubs or switches, to the Cisco Micro Hub.
The Ethernet cable should meet the following specifications:
• Straight-through Ethernet
• 100-ohm Category 3, 4, or 5
• Can be shielded or unshielded
• No longer than 328 feet (100 meters)
If you are connecting another 10BaseT hub or switch, you can also run straight-through 10BaseT cabling from
a a port labeled 1X through 8X on this hub to an MDI port on the other device.
However, if you are connecting a Cisco Micro Hub workstation port (labeled 1X through 8X) to another hub's
MDI-X port, you must use an Ethernet rollover cable. You can identify a rollover cable by comparing the
modular ends of the cable. Holding the cable in your hand, side-by-side, with the tab at the back, the wire
connected to the pin on the outside of the left connector (pin 1) is the same color as the pin on the outside of
the right connector (pin 8). On Cisco cables, pin 1 is white on one connector, and pin 8 is white on the other
connector.
Cable Wiring
This section contains wiring specifications for cables used with the Cisco Micro Hub, including the following:
• 10BaseT port
,• Straight-through 10BaseT cable (RJ-45 to RJ-45)
• Console cable and adapters

10BaseT Port Wiring
Table D-3 describes the wiring for a straight-through 10BaseT cable, which is used to connect the hub to any
devices that use a standard Ethernet LAN interface (for example, to a PC or server).

Straight-Through 10BaseT Cable (RJ-45 to RJ-45)
A console cable kit is provided with your hub to connect a console (an ASCII terminal or PC running terminal
emulation software) to the hub's CONSOLE port.
The console cable kit contains:
• RJ-45-to-RJ-45 console cable (light blue)
• RJ-45-to-DB-25 adapter (light gray)
• RJ-45-to-DB-9 adapter (light gray)
, describes the wiring for the CONSOLE port, the console cable, and both adapters.
