Troubleshooting; Cannot See The Ip Address, Lan Status Led Stays Red; Ip Address Is All Zeroes, Lan Status Led Stays Red; Ip Address Is Three Zeroes And A Number - TDK-Lambda Genesys Series User Manual

15. TROUBLESHOOTING

15.1. Cannot See the IP Address, LAN Status LED Stays Red

If you press and hold the front panel FOLD button for 3 seconds, the voltage display should show "IP-1"
(see section 5.1).
If "IP-1" does not show, then the LAN enable switch has not been set. To fix this:
A. Switch the power supply AC OFF.
B. Verify the LAN Enable switch is UP (see section 3.3.1). You may want to slide it down and up a few times
to clean the switch.
C. Switch the power supply AC ON again.
See the voltage display shows "LAn" for a few seconds during power-up.

15.2. IP Address is All Zeroes, LAN Status LED Stays Red

When viewing the IP address on the front panel (hold the FOLD button, see section 5.1), and you see the
IP address is all zeroes, then the power supply is not connecting to the network.
A. Verify the LAN cable is connected to an active network. Look at the rear panel Link LED (part of the RJ-
45 connector, see section 3.3.2) and verify it is green (and possibly blinking a little). If the LED is not lit,
then the LAN cable is not connected properly.
B. Wait longer and try to read the IP address again. In the Auto-IP mode (see section 4.4), the power supply
will wait a full 40 seconds to assign an IP address after power-up.
C. There could be an address collision on the network where two devices on the network have the same
IP address. If the power supply detects this, it will refuse to assign an IP address and it stays all zeroes.
This only occurs if the power supply is in Static.
addressing mode (see section 4.4). To correct this situation, do either of:
i. Do a front panel LAN Reset (see section 5.3). The power supply will try to get an address from a network
DHCP server or it will create its own address in the
one you are using, then use the front panel to set an IP address that is compatible with your network
(see section 5.2)
ii. Disconnect any LAN device that may have a conflicting address from the network. Switch the power
supply off and on. After 15 or 40 seconds the power supply will acquire its static address.

15.3. IP Address is Three Zeroes and a Number

When viewing the IP address on the front panel (hold the FOLD button, see section 5.1), and you see the
IP address is , then you have to do a LAN Reset (see section 5.3).
0.0.0.x
This situation occurs when, after first powering up, you are viewing the IP address, the address is still zeroes,
and you turn the current encoder and press the FOLD button. This sets a static address (see section 5.2).

15.4. Cannot Communicate to the Power Supply

If the LAN Status LED is green and the front panel shows a valid IP address, but you still cannot open a web
page, VISA or socket connection then try "pinging" the power supply. The ping utility verifies the computer
can send a message and get a response from the power supply over the network.
On a Windows XP computer, open a command line window by:
A. Click the "Start" button, Select "Run..."
B. A "Run" window opens. Type: cmd <Enter>. See the command window open
