648303460000 Rev A IA672-04-01-Rev. I15. TROUBLESHOOTING15.1. Cannot See the IP Address, LAN Status LED Stays RedIf you press and hold the front panel FOLD button for 3 seconds, the voltage display shouldshow “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 downand 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 RedWhen 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 thenetwork.A. Verify the LAN cable is connected to an active network. Look at the rear panel LinkLED (part of the RJ-45 connector, see section 3.3.2) and verify it is green (and possiblyblinking 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 networkhave the same IP address. If the power supply detects this, it will refuse to assign an IPaddress and it stays all zeroes. This only occurs if the power supply is in Staticaddressing 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 anaddress from a network DHCP server or it will create its own address in the169.254.xxx.xxx subnet. If this subnet is not the one you are using, then use thefront panel to set an IP address that is compatible with your network (seesection 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 willacquire its static address.
