Removing the AC power supply
Note: Due to the N + 1 power system architecture, if your chassis 
contains two or three power supplies, Nortel recommends that you turn 
on the power supplies simultaneously. If you wait longer to turn on the 
supplies, the power supply(s) shut off within 7 seconds. To correct this 
condition, turn off the power supplies for a short period of time, and then 
turn on the power supplies again simultaneously. 
Danger: Due to high-energy hazards greater than 240 VA, only 
qualified service personnel are permitted to install and replace Ethernet 
Routing Switch 8600 components.
