Cisco 7100 Series VPN Router Installation and Configuration Guide

Chapter 1 Overview
Field-Replaceable Units
Note
The Cisco 7100 series VPN routers do not support an ISM and an ISA in the same chassis.
The boot LED remains lit when the ISA/ISM is configured for MPPE, and it starts to pulsate after
booting when the ISA/ISM is configured for IPSec. The ISA/ISM functions normally whether the boot
LED is pulsating or is solid. See the
Integrated Service Adapter and Integrated Service Module
Installation and Configuration
for more information on configuring the ISA/ISM.
Caution
To ensure compliance with U.S. export laws and regulations, and to prevent problems later on, refer to
the “Compliance with U.S. Export Laws and Regulations Regarding Encryption” section in the
Regulatory Compliance and Safety Information for the Cisco 7100 Series VPN Routers
document for
specific and important information.
ISM
The Integrated Service Module (ISM) is a service module that resides in slot 5 in Cisco 7100 series VPN
routers. The ISM has three LEDs, as shown in
Figure 1-27
.
Table 1-9
lists the colors and functions of
the LEDs.
Figure 1-27 ISM LEDs
Note
The physical orientation of the ISM LEDs is reversed from that of the ISA (see
Figure 1-27
).
The following conditions must all be met before the enabled LED goes on:
•
The ISM is correctly connected to the backplane and receiving power.

After successfully booting, the boot LED pulses in a “heartbeat” pattern to indicate that the ISM is operating. As
crypto traffic increases, the nominal level of this LED increases in proportion to the traffic level.
