4.
Take the alligator clip on the other end of the straight cord and clip it to the chassis frame of the
ECLIPSE MV/7800.
NOTE
The alligator clip must be attached to a metal portion of the chassis,
avoid painted surfaces.
5.
Place the wrist band around either wrist with the gray side against the skin. Be sure that the metal
portion behind the button makes snug contact with the skin.
NOTE
Both wrist bands included with each ESD kit are identical except for size.
The blue band is slightly larger than the beige band. Use the band that
fits snugly.
6.
Press the yellow resistor end of the coil type cord onto the wrist band snap.
7.
Clip the alligator clip at the other end of the coil type cord to the edge of the black mat.
The ESD kit is now installed and the PCBs can now be removed, handled, and installed.
6.4.3.2 Removing the ESD Kit - To remove the ESD kit, reverse the installation procedure and store all
components of the kit in the storage pockets of the black mat.
6.4.4 CPU Chassis Internal Electrical Connections Check
Refer to to both the configuration sheets packed with the system, and Figure 6-9. Use the following procedure to
check the internal electrical connections in the CPU chassis.
1.
Check the CPU chassis for proper slot assignments. Check the seating of all PCBs.
CAUTION
Use only the slot assignments shown in Figure 6-9.
CAUTION
The power supply captive screw shown in Figure 6-10 electrically bonds
the power supply to the chassis ground. Failure to tighten the power
supply captive screw can cause noise to be generated, degrading system
performance.
2.
Check the part numbers in Tables 6-2 and 6-3 for the proper BMC cables and VNR loopback plugs,
respectively.
