Chapter 2 Quick Installation Procedures
Common Installation Procedures
To ground the shelf, follow these steps:
Step 1 Use a wire-stripping tool to remove approximately 0.75 inch (20 mm) of the covering from the end of
the grounding wire.
Step 2 Insert the stripped end of the grounding wire into the open end of the grounding lug.
Step 3 Use the crimping tool to secure the grounding wire in place in the grounding lug.
Step 4 Locate the grounding receptacle on the chassis.
Step 5 Remove the label that covers the grounding receptacle.
Note Step 6 is optional if you are not using the top cable management guide.
Step 6 Place the lug mounting adapter against the grounding receptacle at the top of the chassis.
Step 7 Place the grounding lug against the lug mounting adapter.
Step 8 Insert two screws through the holes in the grounding lug and the grounding receptacle. Ensure that the
grounding lug does not interfere with other hardware or rack equipment.
Step 9 Install the locking washers and nuts; tighten them to secure the grounding lug to the grounding
receptacle.
Step 10 Prepare the other end of the grounding wire and connect it to an appropriate grounding point in your site
to ensure adequate earth ground for the Cisco ONS 15540.
Cleaning the Shelf
Be careful with the airflow system when you clean the chassis. If the cleaning process must be done
while the system is running, be aware that the airflow system is in operation. Clean the chassis with a
damp cloth only and be careful of the following:
• Do not touch the airflow system while fans are operating.
• Do not use wet tissues for cleaning the chassis.
• Do not use any harsh or abrasive cleaning agents.
Warning
Invisible laser radiation might be emitted from the end of the fiber or connector. Do not stare into the
beam or view directly with optical instruments.
Cleaning Optical Connectors
When installing your optical connectors, consider the following issues:
• Dirty optical connectors are a common source of light loss. Keep the connectors clean at all times
and keep the dust cover installed when not in use.
• Before installing any type of cable or connector, use a lint-free alcohol pad from a cleaning kit to
clean the ferrule, the protective white tube around the fiber, and the end-face surface of the fiber.
• As a general rule, whenever there is a significant, unexplained loss of light, clean the connectors.
