the Flash disk contains the Cisco IOS software image. A 64-MB ATA Flash disk
ships by default with the PRP. Table 1-5 lists the supported Flash disk sizes and
their Cisco product numbers.
System Status LEDs
The PRP faceplate is equipped with two types of system status LEDs: device or
port activity indicators and alphanumeric LED displays.
The device or port activity indicators consist of the following functional groups:
• Two Flash disk activity LEDs (labeled SLOT-0 and SLOT-1)—one LED per
Flash disk slot—Turns on when the slot is accessed.
• Four RJ-45 Ethernet port LEDs (labeled LINK, EN, TX, and RX)—Used in
conjunction with each of the RJ-45 Ethernet connectors. Each connector
includes a set of four LEDs that indicate link activity (LINK), port enabled
(EN), data transmission (TX), and data reception (RX).
• Two Ethernet connection LEDs (labeled PRIMARY)—These two LEDs,
when on, identify which of the two Ethernet connections is selected. Because
both ports are supported on the PRP, the LED on port ETH0 is always on. The
ETH1 LED goes on when it is selected.
The alphanumeric display LEDs are organized as two rows of four characters each
and are located at one end of the card. (See Figure 1-7.) These LEDs display
system status and error messages generated during and after the boot process. The
boot process and the content displayed are controlled by the MBus module
software on the PRP.
