EARPANEL

Figure 2-2. The rear panel of the Pow-R-Boot 5+ (115-VAC model shown).

➀ AC Outlets 1 through 5: The devices whose rebooting you want to control

must be plugged into these outlets. On the 115-VAC model (SWI020A-R2),
the outlets are North American standard NEMA 5-15R sockets; on the 230­VAC model (SWI020AE-R2), they are international standard IEC 320 female
connectors. Each outlet can deliver up to 15 amps, and the total current
drawn from all five outlets must not exceed 15 amps. See Section 3.4 for
more information.

➁ Rate Switch: A four-position DIP switch used to set the control port baud

rate, select the Off-Time, enable/disable the Password Option, and
enable/disable the Read-Only Mode. See Section 3.1 for more information.

➂ RS-232 (Control) Port: A male DB9 connector used for connection to an

external modem or local PC. The Pow-R-Boot 5+ will switch plugs on/off in
response to ASCII commands received via the control port. See Section 3.3
for more information.

④ Default Button: Reads Rate Switch settings and sets parameters accordingly.

This allows the user to change Rate Switch settings without re-booting the
Pow-R-Boot 5+ and connected devices. The Default button can also be used
to bypass the Password Prompt.

➄ 115-VAC Units (SWI020A-R2): Nondetachable 6-ft. (1.8-m) power cord with a

North American standard NEMA-5-15P plug.

CHAPTER 3: Installation

3. Installation

3.1 Setting the Rate Switch

The Rate Switch selects the control port baud rate, sets the boot cycle Off-Time,
and enables/disables the Password Option and Read-Only Mode. If switch settings
are changed while the unit is powered on, press the Default button to re-read the
switch settings. The Default button allows the user to change switch settings while
power is on, without rebooting the PRB 5+ and connected devices.

NOTE

If Rate Switch settings are changed while the unit is powered on, new
settings will not take effect until the Default button is pressed, or the
Pow-R-Boot 5+ is powered off and on.

Switch Position Function UP DOWN

1 Control Port Baud Rate 2400 bps 9600 bps*
2 Off-Time 10 sec. 5 sec.*
3 Password Function Disable Enable*
4 Read-Only Mode Enable Disable*

* = Factory Setting

Control Port Baud Rate: Use DIP-switch-position 1 to select the data rate you want
the PRB 5+ to use for Control port communication. The device attached to the
Control port must be set to the same data rate.

Off-Time: Switch position 2 selects the “Off-Time” for the reboot cycle. The Off­Time determines how long the Pow-R-Boot 5+ will keep AC power off before
restoring it when you send a reboot (toggle power) command.

Select the 10-second Off-Time if the attached device needs to be off longer than
5 seconds in order to properly reinitialize.

Password: When position 3 is set DOWN (factory setting), a password will be
required in order to access the Pow-R-Boot 5+ command mode. The default
password is [Enter]. To redefine the password, please refer to Chapter 4.

12

POW-R-BOOT 5+

Read-Only Mode: When position 4 is set in the UP position to enable the Read­Only Mode, the /P command (Define Parameters) is disabled. This allows the
user to invoke On/Off/Boot commands, but prevents redefinition of parameters
such as the Password and Power-Up Default.

3.2 Rackmounting the Unit

You can use the included screws and rackmount brackets to mount the Pow-R-Boot
5+ in any standard 19" rack. If you would rather mount the PRB 5+ in a 24" rack,
call Black Box for a quote on special brackets.

3.3 Connecting the Master Device

The Control Area on the Pow-R-Boot 5+ rear panels includes a DB9 male
connector labeled “RS-232.” Use this input to connect the PRB 5+ to the master
device. Figure 3-1 shows the control port interface.

ONNECTINGDEVICES TO THE

RS-232 P

ORT

The PRB 5+’s RS-232 port is a DB9 male connector wired in a DTE configuration
similar to that of an IBM

® AT®

computer. When connecting an external modem,

use a standard AT modem cable (our product code EVMBMC).

Make certain the modem is initialized at the same baud rate as the PRB 5+ (Rate
Switch 1). The modem must be placed in auto-answer mode, and set to answer in
one ring. Please refer to your external modem’s users’ guide to determine the
appropriate AT command string.

CHAPTER 3: Installation

3.4 Connecting Switched Devices

Plug the power cords or the power-supply input cords of each of the devices whose
rebooting you want to control into one of the five AC outlets on the rear panel of
the Pow-R-Boot 5+. Make sure that the power switches of these devices are all
turned ON. When the PRB 5+ is powered up, the five AC outlets will be set ON or
OFF as determined by the Power-Up Default string (see Chapter 4).

Each of the PRB 5+’s AC outlets is capable of switching up to 15 amps of AC
power. The total current load on all five outlets cannot exceed 15 amps.

3.5 Powering Up the System

If your Pow-R-Boot 5+ is the 230-VAC model, connect an appropriate power cord
to the IEC 320 male power inlet on its rear panel.

Now plug the Pow-R-Boot 5+’s power cord into a working AC outlet and turn
ON the PRB 5+’s ON/OFF switch. The PRB 5+’s POWER ON LED should light.

When power is applied, the PRB 5+’s five AC outlets will be set ON or OFF as
determined by the Power-Up Default String (described in Chapter 4).

4. Start-Up/Configuration

This section describes the procedures used to access the Pow-R-Boot 5+ command
mode and configure the unit to fit the requirements of your application.

1. Access the Pow-R-Boot 5+: The PRB 5+ is transparent to parity and will accept
7 or 8 bit characters, but will always answer back at 8 bits, no parity. Make
certain your communications program (for example, ProComm

®

) is set for
the appropriate baud rate, bits, and parity. We recommend that you set the
communications program for TTY mode.

a) Via Modem: Start your communications program. Dial the external

modem connected to the PRB 5+. Wait for the Connect message and
proceed to Step 2.

b) Via Local PC: Start your communications program.

2. Password: If the Password function is enabled, the unit will display a prompt.
Key in the Password and press [Enter]. If the password has not yet been
defined, just press [Enter].

NOTE

The Password feature is case-sensitive.
If you forget your password, press the Default button when the

Password Prompt appears, then invoke the /P command to display the
password.

3. The PRB 5+ will display the Status Screen (Figure 4-1).

4. When the command prompt appears, type /P and press [Enter] to define
system parameters. The unit will display a series of prompts.

NOTES

Pow-R-Boot 5+ commands are not case-sensitive.
To skip a prompt without changing its current definition, press [Enter].
To exit from the Define Parameters function, press [Esc] at any time.

Parameters defined up to that point will be saved.

a) Location: Key in a text string that describes the Pow-R-Boot 5+ location

(up to 23 characters).

POW-R-BOOT 5+

NOTES

The Echo Mode will not be enabled/disabled until the /D command is
invoked.

If the Power-Up Default String includes invalid or missing characters,
the /D command will not function.

e) Plug Labels: Allows the user to identify the device connected to each plug

(for example, “SERVER”). Key in the desired name (up to 16 characters)
and press [Enter].

The Power-Up Default String

The Power-Up Default String allows the user to select default On/Off conditions
for each switched AC outlet. When the Pow-R-Boot 5+ is powered up, or when the
/D command (Set Defaults) is invoked, each outlet will be set according to the
Default String.

NOTES

The Power-Up Default String includes five characters; each character
determines the default On/Off condition for the corresponding plug. The
first character applies to plug 1, the second character applies to plug 2,
and so on.

To set a plug to default ON, enter a one (1); to set a plug to default OFF,
enter a zero (0).

If the Default String includes invalid or missing characters, plugs will be
switched OFF when the unit is powered up, regardless of the conditions
shown by the Status Screen. In addition, the /D command will not
function.

Example 1: To set default On/Off conditions as follows:

ON: Plugs 1 and 5
OFF: Plugs 2, 3, and 4

The Power-Up Default String would be defined as “10001.”

Example 2: To set default plug conditions as follows:

ON: Plugs 3, 4, and 5
OFF: Plugs 1 and 2

The Power-Up Default String would be defined as “00111.”

CHAPTER 5: Operation

5. Operation

The device connected to the control port must send ASCII characters at the same
data rate as the Pow-R-Boot 5+. The unit accepts 8 bits no parity, or 7 bits even or
odd parity, but will always answer back at 8 bits, no parity. Access the PRB 5+ as
described in Chapter 4, step 1. When the command prompt appears, the user may
invoke the following commands.

NOTES

Commands are not case-sensitive.
Wait for the command prompt to appear before entering commands.

The prompt will not re-appear until the previous command is complete.
If an invalid command or parameter is entered, the PRB 5+ will respond

with the “?” message.

1. Switch Plug(s) On: To power-on one or all of the five switched plugs, type
/n ON and press [Enter]. “n” is a plug number from 1 to 5 and an asterisk (*)
indicates the command should be applied to all plugs.

2. Switch Plug(s) Off: To power-off one or all of the five switched plugs, type
/n OFF and press [Enter]. “n” is a plug number from 1 to 5 and an asterisk
(*) indicates the command should be applied to all plugs. Note that “OFF”
can also be entered as “OF.”

3. Boot Plug(s): To initiate a Boot cycle at one or all of the switched plugs, type
/n BOOT and press [Enter]. “n” is a plug number from 1 to 5 and an asterisk
(*) indicates the command should be applied to all plugs. Note that “BOOT”
can also be entered as “B.” The PRB 5+ will display a series of periods (dots)
while the Boot cycle is in progress.

4. Status: To display the Status Screen, type /S and press [Enter].

5. Enter Parameters: To define parameters, such as the Location I.D., Power-Up
Default, and Plug Labels, type /P and press [Enter]. (Refer to Chapter 4, step

CHAPTER 6: Troubleshooting

6. Troubleshooting

6.1 Common Concerns

6.1.1 NOP

OWER

O

UTPUT

If the Pow-R-Boot 5+ does not seem to be providing power to one or more of your
devices, make sure all of them are actually plugged into the PRB 5+ and are turned
ON. Also make sure that the PRB 5+ itself is plugged in. Now turn the PRB 5+
OFF and then ON again using its master power switch.

If this doesn’t help, try unplugging the Pow-R-Boot 5+, then unplugging the
switched devices from the PRB 5+ and plugging them directly into the AC outlet
that the PRB 5+ was plugged into. If any devices still don’t seem to get any power,
try plugging them into an outlet you know is working. If they get power then, the
outlet you were using is probably not working; have it examined by a certified
electrician. If they still don’t seem to get power, there is probably something
wrong with the devices themselves.

If all of the switched devices get power when they are plugged directly into the
wall outlet you had the Pow-R-Boot 5+ plugged into, check how much current each
of the switched devices is drawing. If any individual device is drawing more than 15
amps, or if all of the devices put together are drawing more than 15 total amps, you
might have tripped the PRB 5+’s circuit breaker. If this is the case, unplug the
devices connected to the PRB 5+, and then reset the circuit breaker.

After you reset the circuit breaker, or if the circuit breaker has not been
tripped, try reducing the current draw to the PRB 5+’s specified limits, then plug
everything back in the way it was when you started. If any devices still don’t seem
to get power, there is probably something wrong with the PRB 5+; call Black Box at
724-746-5500 for technical support.

6.1.2 U

NITDOESNOTRESPOND TOCOMMANDS

If the Pow-R-Boot 5+ doesn’t seem to carry out the commands you send it, and you
are judging this by the fact that you get no electronic responses from the unit, first
make sure that both the master device and the PRB 5+ are actually plugged in and
turned ON. Then make sure that the cable running from the master device to the
PRB 5+ is pinned straight-through and is securely attached at both ends. Also
make sure that both the master device and the PRB 5+ are set to the same data rate
(see Section 3.1), that the master device is actually sending your commands out of
the port that is connected to the PRB 5+, and that the master device is sending
ASCII in the format of 7 data bits (even or odd parity) or 8 data bits (no parity).

POW-R-BOOT 5+

If these checks turn up nothing, make sure that neither the cable nor the
master device’s serial port are broken (this might require a cable tester and/or an
ohmmeter). If these seem OK, call Black Box for technical support.
