Installing Components
The Control and Switching Module (CSM), compact flash, adapter cards, Fan module,
distribution panel, and cables are field-installable and field-replaceable components.
Warnings and Notes
CSM
The CSM includes one compact flash memory device that can be used to copy and store
system boot software, OS software, and configuration files and logs. The CSM is shipped
with the compact flash memory device installed. The CSM provides the console and
management interfaces to the 7705 SAR-8, as well as external synchronization input and
output interfaces.
To maintain EMC compliance, cables that are shielded and grounded at both ends must be
used with the Console, (Ethernet) Management, and Synchronization interfaces.
Dangers:
• Only trained and qualified personnel should install or replace this equipment.
• Invisible laser radiation can be emitted from an adapter card aperture port when no cable
is connected. Avoid exposure and do not stare into open apertures.
Warnings:
• Electrostatic discharge (ESD) damage can occur if the CSM, compact flash, or adapter
cards are mishandled. Always wear an ESD-preventive wrist or ankle strap connected to
a nearby ground point that is connected to a site grounding point (typically, the grounding
stud on the 7705 SAR-8, or a properly grounded rack or work bench).
• Always place components on an anti-static surface.
• Do not power up a 7705 SAR-8 before verifying that all common equipment (chassis,
power, cooling, and grounding) is connected properly and that the fan module and all
cards in the chassis have the same voltage type.
• Use only approved small form-factor pluggable (SFP) fiber-optic devices in adapter card
ports.
Notes:
• Ports cannot be configured until the adapter card is provisioned.
• Services cannot be configured until the ports are configured.
