Netgear GS752TXS - Stackable Smart Gigabit Ethernet Switch 하드웨어 매뉴얼

The following table describes the system LED designations.

Power 

•

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.

Fan

•

Solid yellow .   The fan has failed.

•

Off .   The fan is operating normally.

Stack Master LED

•

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.

Stack ID

Displays the stack ID, from 1 to 6.

Device Hardware Interfaces

This section describes the hardware interfaces on the smart switch.

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.
