Note There are two types of image files, -P PIE files, and x86-based -PX PIE files. -P PIE files are for use on Cisco
ASR 9000 Series Routers with RSP route switch processors (RSP-4G and RSP-8G). -PX PIE files are for use
on the routers with RSP-440/RSP-440 Lite and RSP-880/RSP880-LT route switch processors, and the Cisco
ASR 9922 Router and Cisco ASR 9912 Router route processors.

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 the alphanumeric displays on the RSP, RP, and line cards.
In a normal router startup sequence, the following 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.
1. The fans in the fan tray receive power and begin drawing air through the chassis.
The fan tray OK indicator is on.
1. As the power-on and boot process progresses for the RSP/RP, the status of the RSP/RP appears on the
alphanumeric display on the front panel of the card.

Identifying Startup Issues

This table shows the contents of the alphanumeric displays on the various RSP/RP cards, as well as the normal
LED states on the power modules (AC or DC) and the fan tray after a successful system startup.
Note For the RSP/RP card to communicate properly to a power module in a power tray, the appropriate input power
should be present.
Description
Consists of one or two fan trays, which circulate air through the card cage to cool
the cards, and two fans in each of the power modules, which circulate cooling
air through the power module.
Consists of four fan trays, which circulate air through the top and bottom line
card cages to cool the cards, and two fans in each of the power modules, which
circulate cooling air through the power module.
