You accidentally flipped the cap over backwards when you were putting the male plug on. If you are using 568B standard that starts with orange/white and ends it brown...make sure that if the orange white is on the left, then the clip on the plug is facing away from you.

Setup router modem


the asus gx1008b is not a modem router, it is a network switch and doesn't need any setting up. all you do is plug in a LAN cable from your internet modem into one of the rj45 sockets on the back - the gray one if it has one then plug anything else in using rj45 LAN cables.

Not connect from console port


Verify that the correct settings and cable/connectors (rollover cable, correct COM port specified) are being used when establishing the console connection.

From the manual-

3.9.2 Connecting to an IBM or Compatible Device

To connect an IBM PC or compatible device, running the VT terminal emulation, to an
Enterasys Networks module Console port (Figure 3-20), proceed as follows:
1. Connect the RJ45 connector at one end of the cable (not supplied) to the Console port on the
Enterasys Networks module.
Connecting to Console Port for Local Management
Hardware Installation 3-31
2. Plug the RJ45 connector at the other end of the cable into the RJ45-to-DB9 adapter (supplied
with the device).
3. Connect the RJ45-to-DB9 adapter to the communications port on the PC.
4. Turn on the PC and configure your VT emulation package with the following parameters:

Parameter Setting

You have a 5-port router. The 5th port can be used either as an "uplink" port (with a cross-over Ethernet cable) or as a "data" port (with a straight-though Ethernet cable).

You've not provided enough details to trouble-shoot the "staying online" problem, i.e., IP-addresses of each of the connected computers/printers, whether you're using CAT3 or CAT5 or CAT5E cables, whether you've tried different Ethernet cables, and whether the router is connected into a UPS that provides "smooth" power.

I am connecting 4 nodes through 2 switch located at 400ft distance. the data transfer is not working. 2 nodes are connected to each switch, both nodes connected to individual switch communicates with each...


Just to clarify, you have 4 computers connected to two ethernet switches. Two computers are connecteh to each ethernet switch and a network cable connecting the two ethernet switches 400ft apart.

For all the computers to communicate with each other, they all need to be in the same workgroup "name".
The cable joining the two ethernet switches need to be connected to the RJ45 UPLINK port on both the ethernet switches, and the uplink port may have a switch (the switch allows it to function as a standard RJ45 port or a RJ45 uplink port).
If there is no RJ45 uplink ports on the ethernet switches then a cross over network cable is needed to connect the ethernet switches together.

Same thing as above, want to se up a LAN connection


Once you connect the 2nd switch - you must power down the cable modem and the original router along with all PC's connected to the network.
Then power up the cable modem,wait 2 minutes,
power up the router - wait 2 minutes, then power up all the switches. Once all downstream devices are on - power up all the PC's and you should be OK.

Cajun P333T doesn't accept input from serial


All info from juliankov appears good.. but thought I'd add a bit of stuff I found on a web site..

http://www.tek-tips.com/viewthread.cfm?qid=300461&page=2

Use a console cable with following minimum pinout (the flat gray one with the RJ45- D9 type converter currently shipping with new P33xx switches will suffice): DB9 Console Port
1 ----------- 6
2 ----------- 3
3 ----------- 2
4 ----------- 4
5 ----------- 5
6
7 ----------- 8
8 ----------- 7
9

Obviously the speed is set to 9600
maybe stop all sessions & try to re-establish a new one. The instruction manual warns u can only run one..

NIC blinks on then off for longer run lines


Please check the RJ45 plugs. the wiring should be as follows: RG45 connector side#1 legs 1236 goes to RG45 connector side#2 legs 1236 see the colors of the wires they should be equal
