Powering Up the Router
132 7705 SAR-M Chassis Installation Guide
Powering Up the Router
Complete the steps in Wiring the DC Inputs (or Wiring the AC Power Converter to the DC 
Inputs for systems using an AC power source) and SFPs before proceeding with the 
power-up and initialization instructions.
The primary copy of the 7705 SAR-M TiMOS software is located on the compact flash 
memory device that is factory-installed. The compact flash device is accessible via an access 
cover that is positioned on the left side of the rear chassis plate. Accessing the compact flash 
device facilitates the commissioning process as the device can be installed pre-programmed 
with the desired software and configuration files. 
Power-Up and Initialization
To power up the router, follow these steps:
Step 1. Turn ON the power to the router at the remote DC power source(s) to initiate the 
boot process. For systems using AC power, plug the AC power converter into an 
AC power source to initiate the boot process.
The logo should illuminate, and the Batt A and Batt B LEDs should be green. If 
only one DC power source is used, only one Batt LED should be lit.
Caution: 
• Only qualified installers following ESD practices should access the compact flash 
device. 
• All power to the chassis must be disconnected while attempting to access the compact 
flash device. 
• The access cover must be fully secured in place before power is applied to the chassis. 
Note: 
• The 7705 SAR-M does not have a power switch or circuit breaker. The system is 
powered on by applying power from the AC or DC power source. For AC power 
supplies, unplug the cord(s) to disconnect the system from the power supply. For DC 
power supplies, use a circuit breaker or a disconnect device to disconnect the system 
from the power supply.
• Configurations and executable software can be stored on the compact flash memory 
device or at an FTP file location.
• You must have a console or Telnet connection to communicate with and provision the 
7705 SAR-M. See Establishing Router Management Connections.
