Communications Statements
The following statement applies to this product. The statement for other products intended
for use with this product appears in their accompanying manuals.
Federal Communications Commission (FCC) Statement
Note: This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his
own expense.
Properly shielded and grounded cables and connectors must be used in order to meet FCC
emission limits. Neither the provider nor the manufacturer are responsible for any radio or
television interference caused by using other than recommended cables and connectors or
by unauthorized changes or modifications to this equipment. Unauthorized changes or
modifications could void the user’s authority to operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) this device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired
operation.
United Kingdom Telecommunications Safety Requirements
This equipment is manufactured to the International Safety Standard EN60950 and as such
is approved in the UK under the General Approval Number NS/G/1234/J/100003 for indirect
connection to the public telecommunication network.
The network adapter interfaces housed within this equipment are approved separately, each
one having its own independent approval number. These interface adapters, supplied by the
manufacturer, do not use or contain excessive voltages. An excessive voltage is one which
exceeds 70.7 V peak ac or 120 V dc. They interface with this equipment using Safe Extra
Low Voltages only. In order to maintain the separate (independent) approval of the
manufacturer’s adapters, it is essential that other optional cards, not supplied by the
manufacturer, do not use main voltages or any other excessive voltages. Seek advice from a
competent engineer before installing other adapters not supplied by the manufacturer.
European Union (EU) Statement
This product is in conformity with the protection requirements of EU Council Directive
89/336/EEC on the approximation of the laws of the Member States relating to
electromagnetic compatibility .
Neither the provider nor the manufacturer can accept responsibility for any failure to satisfy
the protection requirements resulting from a non-recommended modification of the product,
including the fitting of option cards not supplied by the manufacturer.
This product has been tested and found to comply with the limits for Class A Information
Technology Equipment according to CISPR 22 / European Standard EN 55022. The limits
Preface
vii
for Class A equipment were derived for commercial and industrial environments to provide
reasonable protection against interference with licensed communication equipment.
Attention: This is a Class A product. In a domestic environment this product may cause
radio interference in which case the user may be required to take adequate measures.
International Electrotechnical Commission (IEC) Statement

Memory Cards
There are four types of memory card available for use with the R30, R40 or R50 systems.
They are the MRX card, the RLX card, the NFX card, and the SF5 card.
The base MRX memory card looks like the following figure.
Memory cards must be installed starting from memory slot A. Additional memory cards must
be installed using memory slot B first, then C then D.
The system can be upgraded by installing up to three additional memory cards.
Two kinds of memory modules can be installed on memory cards:
• 8MB memory modules which use 4Mb technology.
• 32MB memory modules which use 16Mb technology.

Each memory memory module looks like the following figure.
According to the type of memory modules installed, on the memory cards, the total memory
size is:
• If it has eight 8MB memory modules, the memory card has 64MB memory.
• If it has eight 32MB memory modules, the memory card has 256MB memory.
Reference Information

The next three types of memory cards are shown below. A two bank (8 slots) RLX card, a
four bank (16 slots) NFX card, and a four bank (16 slots) SF5 card. Each bank can house
four memory module kits composed of four memory memory modules each, which comply
with the JEDEC standard for 168 pin, ECC, 60 ns, 5 volt memory modules.

The following table indicates the memory module kits supported by RLX, NFX, and SF5
cards for R30, R40, or R50 systems, and it also shows the resulting memory capacity for
each kit:
Name of the Kit
MM32 4 modules of 8MB each 32MB memory
MM64 4 modules of 16MB each 64MB memory
MM128 4 modules of 32MB each 128MB memory
MM256 4 modules of 64MB each 256MB memory
The maximum memory reachable with this kind of memory card is equal to 1024MB, due to
the fact that up to four of the above indicated kits can be installed on the memory card.
It is not possible to install on the same RLX, NFX, or SF5 card memory modules belonging
to different kits.
Service Guide
Description of the Kit Resulting Memory Capacity
According to both the size and the number of memory module kits installed on the RLX,
NFX, or SF5 cards, these can be divided into the following models:
• NF64 board, based on 4M bit technology, which gives 64MB memory. It houses two
MM32 memory module kits.
• NF128 board, based on 4M bit technology, which gives 128MB memory. It houses two
MM64 memory module kits.
• NF256 board, based on 16M bit technology, which gives 256MB memory. It houses two
MM128 memory module kits.
• NF512 board, based on 16M bit technology, which gives 512MB memory. It houses four
MM128 memory module kits.
• NF1024 board, based on 16M bit technology, which gives 1024MB memory. It houses
four MM256 memory module kits.
Note: The maximum memory configuration yields a system with:
• R30 and R40 - 2048MB (4 x 512MB)
• R50 - 4096MB (4 x 1024MB).
