WARNING
Static electricity damage
Wear a wrist strap connected to the wrist-strap grounding
point of a frame supervisory panel (FSP) or a modular
supervisory panel (MSP) while handling circuit cards. This
protects the cards against damage caused by static electricity.
Obtain a replacement card. Ensure that the replacement card has the same
product engineering code (PEC), including suffix, as the card being removed.
DANGER
Risk of electrocution
Some of the terminals inside the frame supervisory panel
(FSP) have an electrical potential of -48V dc. Remove all
jewelry before replacing a card in the FSP. Do not touch any
terminal in the FSP.
Unscrew the slotted nut on the left-hand side of the FSP.
Open the FSP panel.
Remove the alarm and control card.
