Cautions: To prevent accidental product damage, observe the following precautions:
• Always use proper electrostatic discharge (ESD) gear when handling the control module, backplane, line cards or other internal parts of the chassis.
•Make sure you allow adequate room for air flow around the chassis.
•If you plan to install the chassis in an equipment rack, it is recommended that you install a support tray under the chassis, especially for chassis that are completely filled (no empty control module, power supply, or line card slots).
Before Removing Fiber Optic Protective Caps
Cable assemblies and fiber optic ports are shipped with protective caps to prevent contamination. To avoid contamination, replace port caps on all fiber optic devices when not in use. Cable assemblies and fiber optic ports that become contaminated may experience signal loss or difficulty inserting and removing cable assemblies from fiber optic ports.
Contamination can be removed from cable assemblies by:
1.Blowing surfaces with canned duster (Chemtronics p/n ES1270 or equivalent).
2.Using a fiber port cleaning swab (Alcoa Fujikura LTD p/n
Contamination can be removed from fiber optic ports by:
1.Using the extension tube supplied with canned duster, blow into the optical port, being careful not to allow the extension tube to touch the bottom of the optical port.
2.Reconnect cable and check for proper mating. If problems remain, gently wipe out optical port with a DRY fiber port cleaning swab and repeat step 1.
