Checklist for Power Up
You may power up the Cisco router if the following steps have been completed:
• Mount and ground the chassis securely.
• Connect the power and interface cables.
• Make sure that the external CompactFlash memory card is properly seated into its slot. For
installation instructions, see “Installing and Replacing CompactFlash Memory Cards on Cisco 1800
Series Routers (Modular)”.
• Connect a PC to the router’s console port.
• Start HyperTerminal or a similar terminal emulation program on your PC. Select the appropriate PC
COM port. Set the terminal emulation program configuration for 9600 baud, 8 data bits, 1 stop bit,
no flow control, and no parity.
Note For initial power up, we recommend a direct console connection. After the intial configuration is
completed, a remote modem connection can be used for router management.
Caution To ensure adequate cooling, never operate the router unless the cover and all modules and cover plates
are installed.
Caution To prevent damage to the ejector mechanism, the ejector button next to the CompactFlash memory card
must remain fully seated when not being used to eject a CompactFlash memory card.
LED Indicators
The meanings of the LED indicators for Cisco 1800 series routers are summarized in Table 2-5. For more
detailed information about the LEDs, see Chapter 8, “Troubleshooting Cisco 1800 Series Routers
(Modular).”
Power-Up Procedure
To power up your Cisco router and verify that it completes its initialization and self-test, follow this
procedure. When you have completed the procedure you may begin configuring the router.
