Cisco ONS 15454 Troubleshooting and Maintenance Guide
November 2001
Chapter 2 General Troubleshooting
Check the age of the batteries. Battery performance decreases with age.
Check for opens and shorts in batteries, which may affect power output.
If brownouts occur, the power load and fuses may be too high for the battery plant.
Step 2 If multiple pieces of site equipment show signs of fluctuating power or power loss:
a. Check the uninterruptible power supply (UPS) or rectifiers that supply the equipment. Refer to the
UPS manufacturers documentation for specific instructions.
b. Check for excessive power drains caused by other equipment, such as generators.
c. Check for excessive power demand on backup power systems or batteries when alternate power
sources are used.
2.6.2 Power Consumption for Node and Cards
Refer to the Card and Fan-Tray Assembly Power Requirements section on page 4-5.
2.6.3 Lamp Test for Card LEDs
A lamp test verifies that all the card LEDs work. Run this diagnostic test as part of the initial ONS 15454
turn-up, a periodic maintenance routine, or any time you question whether an LED is in working order.
Procedure: Verify Card LED Operation
Step 1 Click the Maintenance > Diagnostic tabs.
Step 2 Click Lamp Test.
Step 3 Watch to make sure all the LEDs on the physical cards light up for several seconds.
Step 4 Click OK on the Lamp Test Run dialog box.
If a LED does not light up, the LED is faulty. Call the Cisco Technical Assistance Center (TAC) at
1-877-323-7368 and fill out an RMA to return the card.
