Powering Up Cisco 3800 Series Routers
This document describes how to power up your Cisco 3800 series integrated services router.
Caution 
To ensure adequate cooling, electromagnetic interference (EMI) reduction, and safety, never operate the router unless the cover and all modules and cover plates are installed.
Warning The plug-socket combination must be accessible at all times because it serves as the main disconnecting device. Statement 1019
This document contains the following sections:
•Prerequisites
•Power-Up Procedure
Prerequisites
Before you power up the router, make sure you have done the following:
•Securely mounted and grounded the router. See "Installing Cisco 3800 Series Routers in an Equipment Rack" for instructions.
•Connected power and interface cables. See "Connecting Cables to Cisco 3800 Series Routers."
•Connected a PC running HyperTerminal or a similar terminal emulation program to the console port, configured for 9600 bps, 8 data bits, 1 stop bit, no flow control, and no parity. See the "Connecting a Console or Modem" section of "Connecting Cables to Cisco 3800 Series Routers."
Note For initial power-up, a direct console connection is recommended. After the initial configuration is completed, a remote modem connection can be used for router management.
•Chosen passwords for access control.
•Determined IP addresses for Ethernet and serial interfaces.
Power-Up Procedure
To power up your router and verify that it has gone through its initialization and self-test, follow these steps. After you are finished, the router is ready for software configuration.
Note To view the boot sequence, you must have a console connection to the router before it powers up.
Step 1 Make sure that your PC is powered up and connected as described in the "Prerequisites" section.
Step 2 Turn the router power switch on.
Step 3 The SYS LED on the front of the router immediately begins blinking green and the fans operate. On the Cisco 3825 router, the SYS PWR LED shows steady green. The SYS PWR1 and SYS PWR2 LEDs on the Cisco 3845 router do not come on yet.
If these events do not happen, see "Troubleshooting Cisco 3800 Series Routers." Table 4 describes the behavior of other LEDs during the power-up sequence.
Step 4 Startup messages appear on your console. When the startup messages end, the SYS LED shows a steady green. The SYS PWR1 or SYS PWR2 LED on the Cisco 3845 router comes on (depending on which power supply is installed).
Caution Do not press any keys on the keyboard until the messages stop and the SYS LED is steady green. Any keys pressed during this time are interpreted as the first command typed when the messages stop, which might cause the router to reboot. It takes several minutes for the messages to stop.
Note If the rommon 1> prompt appears, your router has booted in ROM monitor mode. For information on the ROM monitor, see Using the ROM Monitor.
Verifying LED Indications
The LEDs described in Table 4 provide power, activity, and status information. For detailed information about LEDs, see the "LEDs" section of "Troubleshooting Cisco 3800 Series Routers."
Note The Cisco 3845 router has two SYS PWR and two AUX PWR LEDs. These LEDs do not come on until the router has booted. Each power supply also has its own LED, which shows steady green to indicate normal operation as soon as router power is turned on.

Verifying the Hardware Configuration
To display and verify hardware features, enter the following commands:
•show version—Displays the system hardware version; the installed software version; the names and sources of configuration files; the boot images; and the amount of installed DRAM, NVRAM, and flash memory.
•show diag—Lists and displays diagnostic information about the installed controllers, interface processors, and port adapters; typical examples are network modules, interface cards (VICs, WICs, HWICs), and advanced integration modules (AIMs).
After your router is powered up, you are ready to begin the initial software configuration. For basic configuration procedures, see Cisco 3800 Series Software Configuration.
Setting the Date and Time
If the router has been exposed to nonoperating environmental conditions, its internal real-time clock (RTC) may not display the correct date and time. To set the RTC manually, use one of the forms of the calendar set command in EXEC mode:
calendar set hh:mm:ss day month year
calendar set hh:mm:ss month day year
Syntax Description
hh:mm:ss
|
Current time in hours (using 24-hour notation), minutes, and seconds.
|
day
|
Current day (by date) in the month.
|
month
|
Current month (by name).
|
year
|
Current year (no abbreviation).
|
The following example sets the RTC to 1:32 p.m. on November 19, 2004:
Router# calendar set 13:32:00 November 19 2004
