The C7200-I/O-GE+E and C7200-I/O-2FE/E do not have a boot ROM component. 2. Some I/O controllers have no Flash SIMM but use a permanently soldered 4-MB or 8-MB flash memory chip instead. (For the location of the 4-MB Flash memory chip, see Figure 1-18 and Figure 1-20. For the location of the 8-MB flash memory chip, see Figure 1-15 and Figure 1-16.) 3. The NVRAM on some I/O controllers is replaced by a 32-pin nonsocketed SRAM component that is soldered onto the card. The SRAM component is made to act like the NVRAM by the addition of some external components, one of which is a 1-inch (2.54-cm) button-type lithium battery. LED Descriptions All I/O controllers have LEDs, and the NPE-G1 and NPE-G2 also have interfaces that have LEDs. The I/O controller faceplate contains LEDs that indicate system and port status; two additional LEDs indicate the status of the Flash Disk or flash memory cards installed in either PC Card slot. A CPU reset button is located next to the IO POWER OK LED or next to the auxiliary port on the I/O controller faceplate. The CPU reset button resets the entire system. The NPE-G2 and NPE-G1 faceplate contains LEDs that indicate system and port status. The RJ-45 and GBIC or SFP ports share the same LINK LED because only one of these ports per interface (0/1, 0/2, or 0/3) can be used at any one time. The ENABLE LED is on if the RJ-45 port is in use. The POWER ON LED on the NPE-G1 or the PWR OK LED on the NPE-G2 is on when the system is powered on, whether 1-40 Cisco 7200 VXR Installation and Configuration Guide OL-5013-09
