Chapter 4 Troubleshooting the Installation

Troubleshooting Overview

For troubleshooting purposes in this chapter, the router consists of these subsystems:

•Power subsystem—Router chassis is shipped with up to two AC-input or DC-input power supply modules installed in the Cisco ASR 9001 Router chassis.

•Chassis backplane power distribution—System transfers +12 VDC power from the power modules to the chassis backplane and distributes it to all the cards through the backplane connectors. The fan tray receives power from the chassis backplane and communicate to the RP CAN Bus controller.

•Processor subsystem—Includes the active Route Processor (RP) card with line card. The RP is equipped with onboard processors. The RP downloads a copy of the Cisco software image to the line card processor.

•Cooling subsystem—Consists of one fantray with 14 fans, which circulate cooling air through the chassis.

Normal Router Startup Sequence

You can generally determine when and where the router failed during the startup sequence by checking the status LEDs on the power modules and RP.

In a normal router startup sequence, this sequence of events and conditions occur:

1.The fan in each power module receives power and begins drawing air through the power supply. The power module input power and output power indicators are on.

2.The fans in the fan tray receive power and begin drawing air through the chassis. The fan tray OK indicator is on.

3.As the power-on and boot process progresses for the RP, the status of the RP appears on the front panel of the card.

Identifying Startup Issues

Table 4-1shows the LED states on the power modules (AC or DC), RP, and the fan tray after a successful system startup.
