Troubleshooting 

If you think your IP-900 series is malfunctioning, follow the corresponding corrective action in the table 

below, according to the applicable conditions. 

If a problem persists, contact the Fujitsu Service Center. 

Electric shock 
Contact your system administrator before checking the voltage of a power 
outlet.  Otherwise, an electric shock may occur. 
 

Is the power cable 

connected? 

Make sure that the power cable is properly 

connected to the outlet. 

Power / 

Starting up 

Power cannot 

be turned on. 

 

Is the outlet voltage normal?

Measure the voltage with a tester to confirm that 

the voltage is normal. 

If another device is connected to the same outlet, 

check the operation of the device. 

The ALM 

LED is on. 

IP-900 series is faulty. 

Troubleshoot from the control terminal. 

Is the ambient temperature 

of IP-900 series higher than 

that in the specifications? 

Adjust the temperature conditions so that the 

ambient temperature of IP-900 series meets the 

specifications. 

Hardware 

The LEDs 

excluding 

100M and 

LINK/ACT 

are on. 

Is there any shielding 

material in the installation 

area? 

Remove the shielding material. 

Is the RDY LED blinking? 

The hardware system is operating while the RDY 

LED is blinking.  Wait until the LED remains on.

Are the LINK LEDs on the  

IP-900 series and hub on? 

If they are not, the UTP cable is not connected.  

Check the UTP cable. 

Operation Commands 

via a LAN 

cannot be 

used (the 

setup menu 

cannot be 

displayed). 

Issue a PING command to 

the IP address of IP-900 

series.  Does it respond? 

If not: 

-  Check the TCP/IP settings (to see whether the 

net mask and gateway address are valid) on the 

client PC. 

-  Start IP-900 series with the default IP address 

and check the IP address by referring to Section 

2.2, "Equipment Operation."  If the problem 

persists, check the operation on the network 

side. 

 

 

Are the browser used and 

its settings valid? 

- Make sure that IE6.0 SP2 or a later version is 

used. 

- Set "Disable proxy" on the browser, and retry the 

operation.
