Device Hardware Interfaces
This section describes the hardware interfaces on the smart switch.
RJ-45 Ports
RJ-45 ports are AutoSensing ports. When you insert a cable into an RJ-45 port, the switch
automatically ascertains the maximum speed (10, 100, or 1000 Mbps) and duplex mode
(half-duplex or full-duplex) of the attached device. All ports support only an unshielded
twisted-pair (UTP) cable terminated with an 8-pin RJ-45 plug.
To simplify the procedure for attaching devices, all RJ-45 ports support Auto Uplink. This
technology allows attaching devices to the RJ-45 ports with either straight-through or
crossover cables. When you insert a cable into the switch's RJ-45 port, the switch
automatically:
•
Senses whether the cable is a straight-through or crossover cable.
•
Determines whether the link to the attached device requires a "normal" connection (such
as when you are connecting the port to a computer) or an uplink connection (such as
when you are connecting the port to a router, switch, or hub).
•
Automatically configures the RJ-45 port to enable communications with the attached
device. The Auto Uplink technology compensates for setting uplink connections, while
eliminating concern about whether to use crossover or straight-through cables when you
attach devices.
GS728TXS/GS752TXS Smart Switch
Solid green . The device is powered on; runtime code is operating.
Solid yellow . The device is booting up.
Off . Power is not supplied to the device.
Solid yellow . The fan has failed.
Off . The fan is operating normally.
Solid green . The switch acts as a master unit in a stack of GS7XXTXS series
switches.
Off . The switch acts as a slave in a stack of GS7XXTXS series switches, or the
stack is operating in standalone mode.
