Do I need a cross over cable?
A crossover cable is only required when interconnecting two devices with the same functionality. Another significant difference between crossover cables and standard patch cables is that each type will have different wire arrangement in the cable for serving different purposes.
In what scenarios do you use a crossover cable?
Use crossover cables for the following cabling:
- Switch to switch.
- Switch to hub.
- Hub to hub.
- Router to router.
- Router Ethernet port to PC NIC.
- PC to PC.
Do I need a patch or crossover cable?
While the patch cable connects two different devices, crossover cables connect two similar devices. If you’re looking to connect similar devices without using hubs or routers, you’ll need a crossover cable. Because of the patch cable’s wire configuration, it’s only designed to connect different devices.
Why it is necessary to crossover the cables to connect two PCs?
Crossover cables flip the transmit and receive wire pairs from one end to the next, so that the transmissions channel on one end corresponds to the receiving channel on the other and vice versa. This eliminates the need for a hub, switch or other intermediary hardware.
Do you need a crossover cable to connect two switches?
No, you do not need a crossover cable to connect two switches, with qualifications. Most (probably all) modern switches have either an auto detect port(s) or a manual uplink switch for a particular port.
What color is a crossover cable?
A crossover is used to connect two Ethernet devices without a hub or for connecting two hubs. A crossover has one end with the Orange set of wires switched with the Green set. Odd numbered pins are always striped, even numbered pins are always solid colored.
Which devices can be connected using a crossover cable?
An Ethernet crossover cable is a type of cable used to connect network devices together directly where they would normally be connected via a network switch or router, such as directly connecting two computers via their network interface adapters. The 10BASE-T and 100BASE-TX Ethernet standards use one wire pair for transmission in each direction.
Can you use a crossover cable as an Ethernet cable?
Most switches, hubs, and routers nowadays have the capability of detecting whether you have a straight through or a crossover cable and adjust accordingly. So even though the wiring is different, you can still use the crossover cable as an ordinary Ethernet cable to connect a computer to a hub.
Do I need a crossover cable for an uplink port?
If you are connected to an uplink port there is no need for a crossover cable. The port is capable of MDI /MDI-X. If you connect to like devices together you need a crossover cable. Most modern networking devices are auto-sensing and will detect the proper polarity regardless of which cable you use.
Do crossover cables connect like devices?
Crossover cables are very similar to straight-through cables, except that they have pairs of wires that crisscross. This allows for two devices to communicate at the same time. Unlike straight-through cables, crossover cables are used to connect like devices without the use of an uplink port.
