CAUTION
Risk of electrostatic damage
When handling processor cards, wear a grounded
antistatic wrist strap so that you do not damage electronic
parts. For more information, see "Avoiding damage from
static electricity" (page 208).
CAUTION
Service loss on active ports
Unspared FPs, including FPs configured with intra-card
APS (port-to-port sparing on a single FP), will
experience a loss of service on any active ports for the
time it takes to replace the FP.
