WARNING
Static electricity damage
Before removing any cards, put on a wrist strap and connect
it to the wrist strap grounding point on the left side of the
frame supervisory panel (FSP) of the LCME. This protects
the equipment against damage caused by static electricity.
DANGER

Ensure that you switch off the correct circuit breaker on the
FSP as described in the following steps. Do not proceed until
you have located and switched OFF the correct circuit
breaker for the RG you are replacing.

Holding a card by the locking levers only may break one or
both levers. Once the card has been pulled half way out of the
