components, and the port adapter installation:
• Verify that the router is plugged in.
• Visually inspect the routers, the port adapters, and the VIP4 and its components to confirm that they
appear to be in working order. Check to see that the LEDs are lighting up.
• Remove and reinstall the VIP4 to reseat it. See instructions in the “Removing a VIP4” section on
page 18.
• If you replaced the SDRAM DIMMs, remove and reinstall them, to reseat them. See the “Upgrading
VIP4 Memory” section on page 31.
• Remove and reinstall the port adapters. See the “Installing or Replacing a Port Adapter on a VIP4”
