Important Note!
Due to the “Hot Swap” capabilities of all card components in the COS chassis, power can be 
applied to the unit at any time before after or during card installation.  It is recommended, 
however, that this feature only be used when necessary. 
This is because  the hot swap  system  can  not protect  from  all  possible errors made by  the 
operator during card installation. 
Powered  on cards  are susceptible to  damage from accidental  shorting due  to conductive 
jewelry, excessive card deflection, or mis-aligned insertion or cards.   To insert or remove 
cards while the chassis power is applied, first carefully read instructions in this manual to 
prevent damage to equipment. 
This unit should be installed in restricted access areas only 
(such as dedicated equipment rooms or equipment closets)
