Chassis Replacement
CAUTION
!
To prevent damage to the equipment from ESD:
1. Ensure that the ED-48000B is grounded when removing or
installing static-sensitive components. This can be
accomplished by leaving the power cords attached to the
chassis and a power source or by implementing standard ESD
precautions, such as placing the chassis on a grounded bench.
2. Wear an ESD grounding strap when handling the CP cards,
16-port cards, and WWN card.
3. Protect the CP cards, 16-port cards, and WWN card with static
bags or grounding pads while they are out of the chassis.
