Prerequisites to replacing a Multiservice Switch 7480
CAUTION
Service loss due to an outage
Replacing a shelf removes it from service for the
duration of the replacement. Minimize the impact of the
outage by rerouting traffic to other nodes in the network
before powering down the device.
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).
