Assembly Exchange The following assemblies are available for exchange.
Part Number Assembly
E1418-69201 Main board and all sheet metal. Does NOT include
plug-on assemblies or expansion board.
E1418-69502 Expansion board. Does NOT include plug-on assemblies.
E1418-66503 Isolated plug-on module (replacement, not an exchange).
Notes When exchanging either the main board or expansion board, you must
disassemble the module and remove all plug-on assemblies before sending
the exchange part. Keep all parts removed in a safe place.
If you are exchanging a main board from a module configured as a 16-channel
device, you must remove the expansion board before sending the exchange part.
CAUTION Almost all electrical components can be damaged by electrostatic discharge
(ESD) during handling. Component damage can occur at electrostatic
discharge voltages as low as 50 volts. Disassemble and reconfigure only in a
static free work area. Minimize handling of assemblies and components. Keep
all assemblies and replacement parts in the original static free packaging.
These procedures should be performed by qualified service personnel at
approved static safe workstations.
To Exchange an
Assembly
1. Contact the nearest Hewlett-Packard Sales and Service Office for
instructions on packaging and shipping.
2. Disassemble the module, using the procedures given earlier in this
appendix, until just the exchange part is obtained. Remove the
plug-on modules and expansion board, if any.
3. Keep all removed parts in a static-safe place. Do not send plug-on
modules with the exchange assembly.
4. Package the assembly in static-safe packaging material.
5. Include a description of the problem encountered as well as your
phone number and return address.
