Spot Checks
This chapter explains how to check for problems and solve them. It is
good practice to carry out regular checks of your MSH equipment and
it could allow you spot a potential problem before it occurs.
Check the following:
■
LEDs
— Press the Lamp Test button located on the MSH display panel.
All yellow LEDs should light continuously and all bi-color LEDs should
flash their two colors alternately.
■
Cabling
— Check that all external cabling connections are secure and
that no cables are pulled taut.
■
Modules
— Check that all modules are secured in position and that
their ejectors are locked. All modules should be flush in the chassis
with each other.
If individual LEDs do not respond to the Lamp Test, the LEDs are faulty.
If, however, all LEDs on a single module fail to light, and all other
checks are satisfactory, there is a fault with the module or the MSH
chassis. Refer to
“Identifying Fault Conditions with the LEDs”
later in this
chapter.
