RIMM Installation Guidelines

2-10
WARNING: To reduce the risk of personalinjury when replacing or
removing RIMMs allow the module being removed from the RIMM
socket sufficient time to cool before touching it. RIMM temperatures
can reach 212°F (100°C).
CAUTION: When handling a RIMM, do not touch any of the contacts.
Doing so may damage the module.
CAUTION: Static electricity can damage the electronic components of
the workstation or option boards. Before beginning these memory
upgrade procedures, ensure that you are discharged of static electricity
by briefly touching a grounded metal object.
This workstation can support either ECC memory or non-ECC
memory. Compaq does not support mixing ECC and non-ECC
memory in the same system. Doing so will cause the system to blink
the NUMLOCK LED on the keyboard continuously and if a speaker
is installed in the system, there will be a short beep followed by
2 long beeps. In addition, the system will not boot the operating
system.
When installing RIMMs, you must follow the guidelines listed
below:
A RIMM can be installed only one way. Be sure to match the
two key slots on the RIMM with the tabs on the RIMM socket.
Push the RIMM down into the RIMM socket, ensuring that it is
fully inserted and properly seated, and that the retaining arms are
locked in place.
CRIMMs must be installed in all empty RIMM sockets on
channels that are used. The CRIMMs are removed when you
populate the sockets with RIMMs. For examples of the correct
configuration sequence, see "Configurations for RIMM
Installation" in this chapter.
