Some I/O controllers have no Flash SIMM but use a permanently fixed 4-MB Flash chip instead. (See Figure 1-9.) 2. 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 Figure 1-12 shows the LEDs on the I/O controller with the Fast Ethernet port that is equipped with an MII port and an RJ-45 port. Figure 1-13 shows the LEDs on the I/O controller without the Fast Ethernet port. Figure 1-14 shows the LEDs on the I/O controller with the Fast Ethernet port that is equipped with a single MII port. Table 1-7 lists I/O controller LEDs and their functions. To use the LEDs for troubleshooting the I/O controller, refer to Chapter 6, "Troubleshooting the Installation," the "Troubleshooting the I/O Controller" section on page 6-6. A CPU reset button is located next to the IO power OK LED or the auxiliary port on the I/O controller faceplate. The CPU reset button resets the entire system. Caution To prevent system errors and problems, use the CPU reset button only at the direction of your service representative. 1-18 Cisco 7206 Installation and Configuration Guide OL-5102-02

LED Descriptions
Figure 1-12
shows the LEDs on the I/O controller with the Fast Ethernet port that is equipped with an
MII port and an RJ-45 port.
Figure 1-13
shows the LEDs on the I/O controller without the Fast Ethernet
port.
Figure 1-14
shows the LEDs on the I/O controller with the Fast Ethernet port that is equipped with
a single MII port.
Table 1-7
lists I/O controller LEDs and their functions. To use the LEDs for troubleshooting the I/O
controller, refer to
Chapter 6, “Troubleshooting the Installation,”
the
“Troubleshooting the I/O
Controller” section on page 6-6
.
A CPU reset button is located next to the IO power OK LED or the auxiliary port on the I/O controller
faceplate. The CPU reset button resets the entire system.
Caution
To prevent system errors and problems, use the CPU reset button only at the direction of your service
representative.
