RIMM Installation

RIMM Installation Guidelines

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.
