Chapter 1 Cisco 10008 Router Overview
Cisco 10008 Router Hardware Description
PCMCIA Card Slots
Two PCMCIA Type II card slots can store the Cisco IOS image or a system configuration file on a flash
memory card. The system can also boot from the software stored on the flash memory card. See
“Figure 5-47Removing the PCMCIA Flash Card” section on page 5-45 for more information about
inserting and removing flash cards from the PRE.
PRE LED Indicators and Switches
LEDs on the front panel of the PRE provide a visual indication showing the status of PRE operation (see
Figure 1-6). The LEDs are separated into three categories:
• alarms
• status
• failure
Alarm relay contacts on the Cisco 10008 router let you connect the router to a site alarm maintenance
system. This allows critical, major, and minor alarms generated by the Cisco 10008 router to be
displayed on both the PRE front panel and to external visual or audible alarms connected to the system.
See the “Connecting Alarm Indicators” section on page 3-26 for more information about alarm
connections.
Pressing the alarm cutoff (ACO) switch on the (primary) PRE during an alarm condition shuts off the
external alarm, but does not deactivate the alarm LEDs on the PRE front panel. Alarm LEDs on the front
panel are deactivated only after the condition that caused the alarm is corrected.
Table 1-3
describes the LEDs and switch on the PRE.
