CHAPTER ONE – INTRODUCTION
The Raymar-Telenetics RM16M Universal Data ShelfTM is a heavy-gauge steel-plated modem rack
chassis. It measures 7 inches high and 10.75 inches deep, and mounts in a standard 19- or 23-inch rack.
The Data Shelf comes in two versions: AC (RM16M VAC-R) and DC (RM16M VDC-R). This guide
covers both versions.
OVERVIEW
The Raymar-Telenetics RM16M Universal Data Shelf has slots that accept 16:
•Modems
•Digital Data Service (DDS) units
•Dial backup units
•Automatic calling units
All of these devices are plug-in printed circuit (PC) cards that slide into the front of the Data Shelf. The
cards can be mixed in any way within the Data Shelf. Each card has been independently tested and
meets Part 68, FCC rules and regulations.
Power, Data Terminal Equipment (DTE), and communications-line connections are made at the back
panel of the Data Shelf (see the “Back Panel Interface Connectors” section). This allows PC cards to be
installed or replaced, without disturbing the cable connections at the back.
The AC version of the Data Shelf accepts either a single power module that occupies two slots, or two
power modules that occupy one slot each. The DC version accepts two power modules that occupy one
slot each. The power modules power all the PC cards in the Data Shelf, converting user-supplied 48
volt DC, or 90 – 265 VAC, input to +15 VDC, -15 VDC, and + 8.5 VDC outputs for distribution to the
PC cards. Regulators on the PC cards convert the plus and minus 15 VDC to plus and minus 12 VDC
and +8.5 VDC to +5 VDC.
NOTE: If two power modules are installed, one powers the Data Shelf while the other
acts as a redundant power source.
Figure 1-1 shows an example of the location and orientation of the modem cards and power module.
For convenience, the front panel of the Data Shelf is hinged to allow easy access to the modem cards
and power module(s) without disturbing the DTE and communication-line connections at the back of the
Data Shelf.

CHAPTER TWO – INSTALLATION
This chapter describes how to install the Data Shelf.
UNPACKING and INSPECTING the EQUIPMENT
Unpack the equipment and compare the contents to the packing list. Inspect the equipment for any
damage that may have occurred in shipment. If you see any damage or if items are missing, contact
Raymar-Telenetics. Keep the shipping container and packing material for future shipment.
SITE PREPARATION
When selecting a location to install the Data Shelf, choose a site that:
•Is clean, well lit, and free from extremes of temperature, humidity, appreciable shock, and
vibration.
•Is within seven feet of a power source that can furnish 48 ±4 VDC at 3.5 amps, or 90 – 265
VAC.
•Is within 50 feet of the associated data terminal.
•Provides at least 36 inches of clearance at the front for operating and maintenance accessibility.
•Provides at least 4 inches at the back of the enclosure for interface cable clearance and
unobstructed airflow.
•Provides at least 1U above and below the enclosure for airflow.
Side and top clearances for rack-mounted equipment are dictated by the rack-cabinet provisions, but
should allow a free flow of cooling air (Figure 2-1). An optional fan tray (1U), part number 0058-1639-
005 (see below), can be installed to improve airflow.

Rev. C Page 7 of 27
Mechanical Assembly
The Data Shelf mounts into a standard 19-inch cabinet and requires 7 inches of vertical panel
space.
The 19-inch Data Shelf also fits into a 23-inch cabinet. This installation requires the rack-
mounting brackets to be removed and reinstalled in the reversed position, so the wider tabs are
used for mounting to the cabinet.
ELECTRICAL INSTALLATION
All power connections are made at the back panel of the Data Shelf.
AC Power (RM16M VAC-R Data Shelf)
Power for the AC version of the Data Shelf (RM16M VAC) is supplied to the power modules
through a separate AC power cord.
One power module is sufficient to power all 16 slots. If only one power source is available, it
can be connected to either input 1 or 2.
After the power module is installed, insert the power cord into the power module socket on the
back of the Data Shelf.
To apply power to the module, plug the opposite end of the power cord into a standard 115/220
VAC grounded wall socket.
Redundant AC Power
Power for the redundant AC version of the Data Shelf (RM16M VAC-R) is supplied to the
power modules through separate AC power cords (see figure below).
After the power modules are installed, insert the power cords into the power module sockets on
the back of the Data Shelf.
To apply power to the modules, plug the opposite ends of the power cords into standard 115/220
VAC grounded wall sockets.
In the event of a power source failure or a power supply module failing, the enclosure will
remain online using the alternate source.

0049-1200-XXX RM16M – USER’S GUIDE 12/29/2010
Rev. C Page 8 of 27
DC Power (RM16M VDC-R Data Shelf)
Power for the DC version of the Power Shelf (RM16M VDC-R) is provided by an incoming
power source that connects to PS1, PS2 (or both) on the back of the Data Panel (see Figure 2-4).
Facing the front of the Data Shelf, PS1 supplies the power module on the left and PS2 supplies
power to the power module on the right.
One power module is sufficient to power all 16 slots. If only one power source is available, it
can be connected to either terminal strip (PS1 or PS2) on the back of the Data Shelf, with shunt
bars installed to connect power to the opposite strip (see Figure 2-5). The bars should always be
installed if only one power source is used and must be removed if two power sources are used.
PS1 and PS2 alarms and chassis ground are connected internally. An alarm condition exists on
the alarm circuit when any operating or supply voltage is lost on either power supply. By
observing which front panel power LED is out, you can identify the faulty power supply.

TELEPHONE LINE INTERFACES
The Data Shelf is FCC certified for connection to the dial-up Public Switched Telephone Network
(PSTN). The following sections describe the standard and optional ways for connecting to the
communications line.
Modular Jack Connectors
The standard Data Shelf back panel has 16 8-pin modular jacks, one for each modem. These
jacks provide the interface for connecting individual modems to the telephone line. Each 8-pin
jack has contacts that are used in various combinations depending on the type of service
installed. Leased-line modems, by comparison, have four contacts: a transmit pair and a receive
pair.
For a description of the modular jack functions, refer to Table C-1 in Appendix C.
Optional Backplanes for Dial Backup Connections
Two optional Data Shelf backplanes are available for use with dial backup modems. These
backplanes provide either modular or mass termination jacks for both dial-up and leased line
telephone line connections. Figure 1-4 and Figure 1-5 show examples of these backplanes.
Modems with dial backup capability can switch to a dial-up line if the leased line fails. For this
reason, both the TELSET/LL and TELCO connections must be made. If the option is not used,
connect the modem to the appropriate service, either leased line or dial-up. If standard modems
(no dial backup capability) are installed they are limited to connection to the TELCO only.
For a description of the modular jack functions, refer to Table C-1 in Appendix C.
NOTE: Telco jack pin functions are identical for both standard and dial backup
modems. Similarly, DTE connectors are the same as for standard modems.
INSTALLING and REMOVING POWER MODULES
Power modules generate power that is bused to the 16 modem edge connectors on the recessed power
bus. Power modules are available in AC and DC versions.
AC Power Module
The AC power module is a 2-slot module designed for the RM16M VAC-R Data Shelf. The
RM16M VAC-R Data Shelf can hold a maximum of one AC power module.
