Cisco Systems Cisco 12008 manual MEM-12KRP-FD64=

Overview of the Cisco 12008

Flash memory also functions as a Trivial File Transfer Protocol (TFTP) server to allow other servers to boot remotely from stored images or to copy them into their own Flash memory. The onboard Flash memory (called bootflash) contains the Cisco IOS boot image, and 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.

1.Standard Type 1 and Type 2 linear Flash memory cards also are supported, although they may not have the capacity to meet the requirements of your configuration.

2.64-MB ATA Flash disk is the default shipping configuration.

System Status LEDs

The sections describes the two types of system status LEDs used on the PRP: LED 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)—1 LED per Flash disk slot: these go 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 4 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. Since both ports are supported on the PRP, the LED on port ETH0 is always on. The ETH1 LED goes on when it is selected.
