3 SAFETY
Read the installation instructions before connecting the chassis unit to the power source. Do
not install the chassis unit with power on.
The chassis or the portable unit is intended for installation in restricted access areas. A re-
stricted access area can be accessed only through the use of a special tool, lock and key, or
other means of security.
Blank face plates and cover panels serve three important functions: they prevent exposure to
hazardous voltages and currents inside the chassis, they provide electromagnetic interference
shielding and they direct the flow of cooling air through the chassis. Do not operate the chassis
unit unless all modules, face plates, front covers and rear covers are in place.
Only trained and qualified personnel should be allowed to install, replace or service this equip-
ment.
This equipment must be installed and maintained by service personnel as defined by AS/NZS
3260. Incorrectly connecting this equipment to a general-purpose outlet could be hazardous.
If SFP modules are used ensure proper precautions are taken to protect eyes against harmful
infrared radiation. Do not look straight into the SFP module or fibers connected to the SFP
module. The SFP modules employed are certified in Laser Class 1.
Ultimate disposal of this product should be handled according to all national laws and regula-

Do not work on the system or connect or disconnect cables during periods of lightning activity.
The chassis or the portable unit requires short-circuit (overcurrent) protection. Ensure that the
protective device is rated not greater than 120 VAC, 15 A; 240 VAC, 16 A; 60 VDC, 20 A.
