Installing the MCC Card
Use a small- to medium-size flat-blade screwdriver to install the MCC card.
NOTE:
All standalone 8600 chassis (i.e., chassis that are not daisy-chained to other
HotWire 8600 DSLAM chassis) require an MCC card, but only the base
chassis of a multi-system stack requires an MCC card.
Do not discard filler plates. Each slot in the chassis must contain a circuit
card or a filler plate to maintain the required EMI shielding and to prevent air
leakage from the forced air cooling. Air leakage could result in overheating
which may cause the power to the circuit cards to be shut off. Store all
unused filler plates in a safe place. You may need to use the filler plates to
cover open slots in the chassis at a later time.
! HANDLING PRECAUTIONS FOR
STATIC-SENSITIVE DEVICES
This product is designed to protect sensitive components from damage
due to electrostatic discharge (ESD) during normal operation. When
performing installation procedures, however, take proper static control
precautions to prevent damage to equipment. If you are not sure of the
proper static control precautions, contact your nearest sales or service
representative.
