CHAPTER 2: Introduction
2. Introduction
The FradSwitch A/S 3 Port provides easy, cost-effective access to a packet-switching network. It also provides packet-switching capability for both X.25 and Frame
Relay.
The FradSwitch has three ports which support aggregate data rates up to
2 Mbps. Each port can be configured—through a firmware-resident set of configuration menus that you can access with an attached terminal—to use any of the following protocols: X.25, Frame Relay, HDLC, STM, asynchronous, or
IP/SLIP. Switching between ports is provided for X.25, Frame Relay, and encapsulated protocols.
Depending on the model you ordered, the FradSwitch’s ports can be any of several combinations of EIA/TIA RS-232 (ITU-T V.24) or RS-530 or ITU-T V.35 or
X.21. These physical interfaces can be DCE or DTE (user-configurable). The
“-DDS” models have a DDS interface on port 1 which is always DTE.
The FradSwitch A/S 3 Port supports a wide range of applications. For information on configuring the FradSwitch’s firmware, refer to the Packet Switching
Guide (call Black Box for a copy if you did not receive one with your FradSwitch).

FRADSWITCH A/S 3 PORT
3. Configuration and Installation
The FradSwitch A/S 3 Port is delivered completely assembled. It is designed to be installed as a desktop unit or mounted in a 19" rack.
After installing the unit, refer to the Packet Switching Guide for systemconfiguration information and procedures, as well as for troubleshooting information (including testing and diagnostics instructions) if you have any difficulties.
3.1 The Complete Package
The complete FradSwitch A/S 3 Port package includes:
• A FradSwitch A/S 3 Port,
• Its power cord,
• This manual,
• An RJ-45 to DB25 adapter cable for the control port (see Section 3.5.1), and
• V.35 and X.21 models only: An adapter cable for each V.35 or X.21 port to patch the FradSwitch’s DB25 connector to a V.35-native M/34 connector or an X.21native DB15 connector.
If anything is missing or damaged, contact Black Box right away.
NOTE
We suggest that you save the packing material and carton in case it becomes necessary to store, ship, or return the FradSwitch.
14
CHAPTER 3: Configuration and Installation
3.2 Site Requirements
Power:
The FradSwitch A/S 3 Port unit should be installed within 5 ft. (1.5 m) of an easily accessible, grounded AC outlet capable of furnishing power at the voltage it needs (100 to 230 VAC).
Control-Port Connections:
The FradSwitch A/S 3 Port has an RJ-45 connector for its asynchronous supervisory-control port (see the Appendix for this port’s pinout).
Main-Link Connections:
The FradSwitch A/S 3 Port has three main-link connectors. What type of connectors these are depends on which interface(s) you ordered for your Switch:
RS-232: DB25 female
X.21: DB25 female patched to DB15 female with included adapter cable
V.35: DB25 female patched to M/34 female with included adapter cable
RS-530: DB25 female
DDS: RJ-48 female
The pinouts for these interfaces are listed in the Appendix.
Front and Rear Clearance:
When the FradSwitch A/S 3 Port is installed in a
19" rack, allow at least 36" (90 cm) of clearance in front of it for operator access and 4" (10 cm) of clearance behind it for interface-cable connections.
Environment:
The ambient temperature in which the FradSwitch A/S 3 Port operates should be 32 to 122˚ F (0 to 50˚ C), at a relative noncondensing humidity of not more than 90%.
15
FRADSWITCH A/S 3 PORT
3.3 Hardware Configuration
The FradSwitch A/S 3 Port contains two different types of printed circuit boards, as shown in Figure 3-1 below. The main board contains most of the FradSwitch’s circuits, and has two jumpers. Three main-link interface boards carry interfacespecific logic. The following subsections provide information on the functions and default settings of the internal jumpers, as well as step-by-step instructions for setting them. (Note that the default settings of the FradSwitch’s jumpers are usually suitable for most applications.)
All other configuration of the FradSwitch A/S 3 Port is done after you install it, through its firmware-based “command facility” (menu system). For detailed instructions, refer to the Packet Switching Guide.

There are several jumpers mounted on the FradSwitch A/S 3 Port’s main circuit board. On non-X.21 models, only one of these jumpers—JP25—is user-settable; on
X.21 models, so are jumpers JP4, JP5, and JP6. Refer to the descriptions of these jumpers below, and to Figure 3-2 on the next page. (All other jumpers on the main circuit board are either for factory functions or are reserved for future use. Do not change them from their factory-default settings.)
JP25, the INIT/NOR Jumper
Use this jumper to select which set of stored firmware-configuration parameters the FradSwitch A/S 3 Port will load at power-up and use as its default. The jumper has two positions:
NOR Normal operation (the factory-default setting). The FradSwitch A/S
3 Port loads and uses the set of parameters mostly recently selected and saved to NVRAM by a user.
INIT Initialization. The FradSwitch A/S 3 Port loads and uses its original factory-default configuration. For more information about configuring the Switch, including the unit’s factory-default settings, refer to the
Packet Switching Guide.
X.21 Models Only: JP3 (BRG3), JP4 (BRG2), and JP5 (BRG1), the X.21 DCE Jumpers:
In their factory-default settings, which are appropriate for operating the
FradSwitch A/S 3 Port’s X.21 ports as DTE interfaces, these jumpers are not connected. If you want any of the Switch’s X.21 ports to function as a DCE, you’ll have to connect its jumper here, as well as move its jumper bank to “DCE” on the interface board (see the next section).
For Link 1 to be DCE, connect the JP5 (BRG1) jumper. For Link 2 to be DCE, connect the JP4 (BRG2) jumper. For Link 3 to be DCE, connect the JP3 (BRG3) jumper.

The FradSwitch A/S 3 Port’s main-link ports can be any of these interfaces, each of which is controlled by an interface-specific “interface board” (daughterboard) mounted on the main circuit board:
• EIA/TIA RS-232 (ITU-T V.24)
• EIA/TIA RS-530
• ITU-T V.35
• ITU-T X.21
• DDS CSU/DSU (Port 1 only)
Each interface board can be configured as DCE or DTE by moving the jumper bank on that board. The jumper bank, marked “DCE
↔ DTE,” consists of interlinked multiple jumpers that must be moved together, as shown in Figure 3-3 below.
U1-X21
DTE
↔DCE
Figure 3-3. A DTE/DCE jumper bank (interface board for an X.21 port shown).
When a board is set as DTE, the port receives its clock from outside and so must be firmware-configured for “external clock.” By contrast, when a board is set as DCE, the port uses the Switch’s own clock and so must be configured for “internal clock.” (Refer to the Packet Switching Guide for more information.)

FRADSWITCH A/S 3 PORT
3.4 Installing a Switch in a 19" Rack (Optional)
The FradSwitch A/S 3 Port can be installed in a 19" rack, where it takes up 1U
(1.75", 4.4 cm) of vertical space. A rackmount kit (our product code LRRACK) provides the hardware necessary to do this: two long-arm brackets, four screws, and four washers.
To prepare the Switch for rack installation, attach the two rackmount-kit brackets to its sides. Each bracket is fastened with two screws and two washers, inserted into the two front holes on the Switch’s side as shown in Figure 3-4 below
(nuts are already in place, inside the unit). Now fasten the brackets to the side rails of the rack with four of your own screws (not included), two on each side.

CHAPTER 3: Configuration and Installation
3.5 Attaching Cables to the Switch
The FradSwitch A/S 3 Port has three numbered connectors on its rear panel for its main device/WAN links (of which, on “-DDS” models, Port 1 will be the dedicated
DDS port), plus an RJ-45 connector on its front panel that serves as the supervisorycontrol port. See the Appendix for the pinouts of these ports.

The FradSwitch A/S 3 Port comes with a 6-ft. (1.8-m) RJ-45 male to DB25 female adapter cable. You can attach the cable’s RJ-45 plug to the Switch’s control port and plug its DB25 female connector directly into the DB25 male serial port of most
RS-232 ASCII terminals, older IBM PC compatible computers, and other terminaltype equipment. Alternatively, with a standard DB25 male to DB9 female adapter, you can run this cable from the Switch’s control port to the DB9 male serial port of a newer IBM PC/AT or PS/2 compatible computer.
If you want to attach the control port to a terminal-type device at a greater distance, you can do one of two things. You can either run high-quality straightthrough-pinned RS-232 or AT cable from the DB end of the adapter cable to your device, or you can put aside the adapter cable, attach a specially pinned modular adapter to your device, and run straight-though-pinned RJ-45 male to RJ-45 male
8-wire twisted-pair cable from the control port to the adapter. (Call Black Box
Technical Support to discuss either application. In neither case should you exceed the normal RS-232 maximum distance of 50 ft./15.2-m.)

You can always use straight-through cables for these connections if you set the
FradSwitch A/S 3 Port’s interface-board DTE/DCE jumpers correctly (see
Section 3.3.3
). (On X.21 models, the X.21 DCE jumpers also need to be set correctly—see Section 3.3.2.) Beyond this, the type of cable you connect depends on the link-port’s interface:
• How you connect an RS-232 device to a Switch’s RS-232 main-link port will depend on what type of connector the device has. If it’s a DB25 male or female, run a shielded straight-through-pinned RS-232 cable—such as our
EDN25C-MF or EDN25C-MM respectively—between the Switch port and the device. If the device’s connector is a DB9 male—as will be the case if you are attaching a terminal-emulating PC to upgrade the Switch’s software (see
Section 4.3
)—run a PC/AT modem cable such as our EVMBMC between the
Switch port and the device. (Be aware that devices with normal DB9 RS-232 connectors, pinned as TIA-574, must communicate asynchronously with the
Switch. This is because the standard TIA-574 pinout does not include the sync clocking signals present on the full RS-232 DB25 pinout.)
• To connect an RS-530 device to a Switch’s RS-530 main-link port, run a shielded straight-through-pinned RS-530 cable—such as our EVN530-MM— between the Switch port and the device.
• To connect a V.35 device to a Switch’s V.35 port, attach the included DB25 male to M/34 female adapter cable to the port. Then run a run a shielded straight-through-pinned V.35 cable—such as our EYN450-MM—between the
M/34 end of the adapter cable and the device.
• To connect an X.21 device to a Switch’s X.21 main-link port, attach the included DB25 male to DB15 female adapter cable to the port. Then run a shielded straight-through-pinned X.21 cable—such as our EGM16E-MM— between the DB15 end of the adapter cable and the device.
NOTE
The cables you attach to the FradSwitch A/S 3 Port should be shielded, in order to comply with FCC rules. The Switch and its data interfaces will work well even if the cables are not shielded, but some radio interference may occur.

AC P
OWER
AC power should be supplied to the FradSwitch A/S 3 Port through a power cord terminated by a standard 3-prong plug, such as the 5-ft. (1.5-m) cord provided with the Switch. Connect the cord’s outlet to the Switch’s rear-panel power-inlet, then attach the cord’s plug to a standard grounded AC outlet.
CAUTION!
When you apply power to the FradSwitch A/S 3 Port, make sure that it is properly connected to the site’s grounding (earth) system. Make sure to always use a power cord with a ground lead running from the ground terminal of the Switch’s power inlet to the ground contact of a utilitypower (mains) outlet. Do not leave the Switch ungrounded by using a power cord, power strip, extension cord, BPS/UPS, or outlet without a ground conductor.
In the course of normal operation under normal conditions, your
FradSwitch A/S 3 Port’s fuse (located in the Switch’s rear panel above the Switch’s power inlet) should never blow. But if it ever does, make sure that you replace it only with a new fuse rated for the same required current (see the rear-panel labeling). Do not use repaired fuses or shortcircuit the Switch’s fuse holders. If you ever suspect that the Switch’s fuse might have blown or been damaged, unplug the Switch and make sure it is not powered up again until the problem can be checked and fixed.
Operating the Switch when it’s not properly grounded or does not have proper fuse protection could damage the Switch and any attached equipment, and could also pose a potentially fatal shock hazard.

CHAPTER 4: Operation
4.2 Basic Operating Instructions and Indications
Once you install and configure the FradSwitch A/S 3 Port, it normally operates unattended. After initial setup, operator intervention is only required when the
Switch has to be reconfigured or if something goes wrong. Note that the Switch stores its configuration in nonvolatile RAM (NVRAM), so it won’t lose its configuration if it loses power.
4.2.1 P
OWER
-U
P
The FradSwitch A/S 3 Port will begin operating as soon as you attach its power cord to its rear-panel power inlet and plug the cord into AC power; the Switch has no ON/OFF switch. The Switch’s PWR LED should light and some or all of its other LEDs should flash. (Which other LEDs flash might depend on how the
Switch is configured.) If the ERR, OVF, or TEST LEDs light, make sure that after a short interval (during which the Switch performs its power-up self-test) the LED goes dark again.
4.2.2 N
ORMAL
O
PERATION
During normal operation, the PWR and SYNC LEDs should be continuously lit and the TEST, OVF, and ERR indicators should remain dark. Channel- and link-activity
LEDs should flash according to the traffic load, and should be dark when the channel is idle.

4.3 Upgrading the Switch’s Firmware
Because the FradSwitch A/S 3 Port has flash memory, you can upgrade its firmware without replacing its EPROMs. To do so, take these steps:
1. Connect a PC running terminal emulation to the switch’s control port.
Configure the terminal emulator to transmit and receive at 9600 bps using no parity, 8 data bits, and 1 stop bit (“9600,N,8,1”).
2. When the asterisk “*” prompt appears on the screen, type C0 and press
[Enter]. You will be prompted to enter a password; just hit [Enter] (the
Switch’s default password state is no password at all).
3. The Main Menu will appear:

5. Troubleshooting
5.1 Things to Try First
If a problem occurs with your FradSwitch A/S 3 Port, try these things first:
• Make sure that the Switch is actually powered ON (the PWR indicator should be lit).
• Make sure all cables are properly connected.
• Make sure that all equipment connected to the Switch is powered ON and operating normally.
• Check the Switch’s indicators.
• Make sure that the configurations of the local FradSwitch A/S 3 Port and the remote PAD or switch correspond to the requirements of the equipment connected to their channels.
In case these preliminary checks do not correct the problem, either press RESET or turn the Switch OFF and then ON again. If the problem persists, refer to the
Packet Switching Guide for additional things to try. If this still doesn’t help, see the next section.
5.2 Calling Black Box
