4.1 Network Settings

4.1.1 Review TCP/IP Settings

During unit startup, the LED ‘Matrix’ will flash as the switch boots up, and then any slots with cards or any of

the 4+4 SFP/Copper ports with n Ethernet link will light during normal operation. Refer to Chapter 2 section 2.2.5

TCP/IP Configuration for the SNMP agent settings. Be sure you have a valid IP address for the attached network,

that the subnet mask is properly set and that the default gateway is set if you wish to manage the GSW from a

remote network.

Attach a network cable to any one of 4 (four) rear panel LAN (10/100/1000) connectors using a straight cable if

connecting to a HUB or to another MDI device, such as direct connection to a workstation. The Link LED should be

on or flashing. No link LED means no link. From any PC on the network, confirm the switch can be pinged.

Figure 4.1 Ping

The "ipconfig" command from a command window in NT will display the workstation's IP, subnet and gateway

settings. The "ping" command will send an ICMP protocol message to the GSW SNMP agent, which in turn should

reply. If no reply, double check all network connects, connect directly from a workstation to the GSW, or as a last

resort replace the GSW card of the FRM220A.
