Installing Network Cables
| | | | | |
Your | Ethernet | Hub | is denominated as an 12-port, |
or 16-port, or 24-port | Ethernet Hub according to |
the | number | of its | front-panel | 1OBaseT ports. |
Additionally | it | has two ports whose connectors are |
on | the rear | panel: one lOBase2 port (BNC |
connector), | and | one lOBase5 port | (AUI connector). |
These two un-numbered rear-panel ports are logically equivalent with the numbered ports on the front panel of the Ethernet Hub.
By using a rear-panel connector of the Ethernet Hub to connect into an existing coaxial network cable, you can add on a star-topology subnet, connected through the Ethernet Hub’s numbered front-panel ports. Alternatively, you can connect into an existing star-topology through a front panel port of the Ethernet Hub, and then add on a bus-topology subnet by connecting the subnet bus to a rear-panel connector of the Ethernet Hub (irrespective of any star-topology subnet that may also be supported by the Ethernet Hub’s front- panel ports). In either case, the unused rear- panel connector always remains available to connect a second coaxial cable (alternative type of coaxial cable).
When the Ethernet Hub has no coaxial trunk connection, then both of the rear panel connectors remain available for coaxial station-cable connections. It is useful to keep this in mind when you have some station equipment whose
adapters | have | no | 1OBaseT | port | (RI-45 | connector), |
and thus | can | only | be connected to | the | hub through |
a coaxial | cable. | | | | |
