Netgear GSM7224 설치 가이드

 

This chapter describes the hardware features of the NETGEAR Model GSM7224 Managed Layer 2 Gigabit 
Ethernet Switch. Topics include: 

•  Front and back panels 
•  10/100/1000 Mbps auto-sensing RJ-45 ports 
•  SFP module bay 
• LED 

descriptions 

• 

Console port

 

Figures 2-1 and 2-2 show the key components on the front and back panels of the NETGEAR Model 
GSM7224 Managed Layer 2 Gigabit Ethernet Switch. 

The front panel contains LEDs, RJ-45 jacks, SFP module bays, and a console port.  The back panel has a 
standard AC power receptacle for accommodating the supplied power cord.

As Figures 2-1 and 2-3 show, the GSM7224 Managed Layer 2 Gigabit Ethernet Switch has 24 10/100/1000 
Mbps RJ-45 ports. The RJ-45 ports are auto-sensing 10/100/1000 Mbps 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- or full-duplex) of the attached device. 

To simplify the procedure for attaching devices, all RJ-45 ports support Auto Uplink. This technology lets 
you attach devices to the RJ-45 ports using 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 connecting the port to a PC) or an “uplink” connection (such as when connecting the port 
to a router, switch, or hub)
