CHAPTER 2: Overview
2. Overview
The Remote Management Switch (part number SW555A or SW555AE) can be
used for serial switching and as an AC power control system. A Remote
Management Switch with Modem (part number SW556A-R2 or SW556AE—
includes 56 kbps modem) is also available. See Figure 2-1.
MANUAL
Figure 2-1. The switch’s front and rear views.
2.1 Port Selector
As a port selector, the Remote Management Switch allows one master RS-232
asynchronous channel to be selectively switched to any of up to 4 ports. You can
use the switch as a port selector to provide access from one modem or terminal to
multiple systems. Typically, you can use the switch to access out-of-band
management ports on multiple devices. By using simple escape strings or menu
commands, you can select which port to access. Ports can also access the master by
raising a control lead. While accessing a port, the switch is passive, allowing all data
to pass until it receives a user-programmable command.
2.2 Power Controller
You can control the four AC outlets on the Remote Management Switch. The
Switch accepts code or menu commands from its master port to power on, off, or
reboot the outlets.

CHAPTER 3: Installation
The four switched ports, A through D, are wired DCE (output data on pin 3, RD).
The master port is wired as DTE. To directly connect a terminal device to the
master port, you need a null-modem cable (see Figure 3-2).
Control leads required vary from device to
device. Consult your device’s operations
manual for details on your specific needs.

REMOTE MANAGEMENT SWITCH
4. Operation
4.1 Four Modes of Operation
You can operate the Remote Management Switch in four possible ways: menu
selection, escape code sequences, lead control, and manual control.
4.1.1 MENU SELECTION
By connecting to the master port, you can switch to any of the four ports (A
through D) or operate any of the four relays. The menu system allows convenient
naming of each port and relay, as well as allowing setup of all Remote Management
Switch parameters. A login procedure protects the menu system from
unauthorized access.
4.1.2 ESCAPE CODE SEQUENCES
You can bypass menu operation by transmitting escape codes to the master port of
the switch. You can partially define these escape codes through the setup menus.
4.1.3 LEAD CONTROL
This option allows any of the four ports to access the master port by raising its
Request to Send (RTS) or Data Terminal Ready (DTR) control lead. This is an
alternative to menu selection (described in Section 4.1.1).
4.1.4 MANUAL CONTROL
You can select ports locally via the switch’s front-panel pushbutton.
4.2 Menu Control
You can control the Remote Management Switch principally through an ASCII
terminal interface. Connect to the modem using a terminal or PC running
terminal emulation software. The factory default parameters for communication
are (9600, 8, n, 1):
• 9600 bits per second
• 8 data bits
• no parity
• 1 stop bit
12
CHAPTER 4: Operation
The Remote Management Switch automatically detects the rate of operation,
allowing connection at 300 bps to 115.2 kbps. Using the default speed will allow
the fastest access to the unit. To invoke the auto rate detector, press the Enter key
one or more times as needed. When the Switch detects the rate, it will respond
with the security login prompt:
Login >
Enter the default security code (the default code is “TEST,” all caps, case-sensitive).
Three incorrect attempts to enter the security code will cause the switch to
terminate the call. When you enter the correct code, the main menu appears (see
Figure 4-1).

Once you select a port, the switch will clear the screen and generate the following
message:
x Selected (x=the programmed name of the port)
Enter ESC{PASSWORD}ESC to return to menu
At this point, the master port is connected through to the port selected. The
Remote Management Switch is passive to the messages sent between the master
port and the port selected. To terminate the session with the current port and
bring back the menu, enter the escape character plus the security code and
another escape character (for example: <Esc>TEST<Esc>).
4.2.2 POWER CONTROL

3) Baud Rate. The Remote Management Switch can operate at speeds from 300 to
115,200 bps. Simply enter the desired baud rate followed by the Enter key. Valid
selections are 300, 600, 1200, 2400, 4800, 9600, 19,200, 38,400, 57,600, and
115,200.
The baud rate set only affects the code and menu control of the switch. Once
connection to a port is made, the switch is transparent to the speed and character
format sent.
4) Parity and Data Bits. The Remote Management Switch can operate with a 7- or
8-bit data frame, and odd, even, or no parity. You need only set the parity: None,
Even, or Odd. The switch automatically determines the number of data bits and
stop bits.
16
CHAPTER 4: Operation
5) Lead Control. This selection determines whether control leads from the
switched ports can be used to access the master port. The factory default is lead
control disabled. Select Yes or No.
6) Command Response. The switch can send a response to escape sequences to let
the operator know that the switch has taken place. The factory default is responses
disabled. Select Yes or No to change the setting.
7) Modem or Terminal Mode. Sets the switch for either terminal or modem use.
Each time you select 7 Mode, this setting toggles.
• Modem mode: The Remote Management Switch monitors the DCD lead from
the master port. Once the call is established, send the Escape to invoke the
auto rate detector, if required, then the Enter key to generate the Login
prompt, or any valid control code. Three unsuccessful login attempts causes
the switch to hang up the modem. Use this setting when the switch is
connected to a dial modem.
• Terminal mode: The Remote Management Switch does not monitor the
connection status of the master port. This mode allows an unlimited number
of login attempts. Each time it receives an enter key, the switch issues a new
login prompt. After three tries, the login prompt is suppressed to allow you to
enter control codes. Use this mode for direct cable connections from a PC or
terminal to the switch.
8) Cycle Time. Sets the length of time in a relay Cycle command. This time is set
once for all relays controlled. Selections from 1 to 255 are valid.
9) Time Out. To prevent one port from dominating access to the master port and
locking out other selections, the switch incorporates a timeout feature. With this
feature enabled, the switch monitors the data activity received by the master port.
When no data is received by the time as set, the currently selected port is deselected. Set the Timeout from 1 to 99 minutes. Setting the Timeout to 0 (the
default setting) disables the feature and allows unlimited time with no data
received. The timeout feature affects all selection modes.
X) Exit the Programming Mode. Exit the programming menu and activate all
current settings. If you have changed the baud rate and/or character format, Exit
will enable those changes. From the main menu, “X” terminates the current
session and a new connection to the Remote Management Switch will be required.
The calling system must terminate the session and hang up the modem.
17
REMOTE MANAGEMENT SWITCH
4.3 Escape Code Control
The Remote Management Switch allows direct computer control using simple
ASCII strings. These codes can control the port selection and relay operation. To
access the switch for code control, enter the commands as shown below. To invoke
the auto-rate detector, press the Escape key one or more times, until the switch
responds with BLACK BOX READY.
<Esc> The Escape character (Decimal 27 Hex 1B)
<Sec> The Security code (Default=TEST)
<x>

D=De-energized)
CHAPTER 4: Operation
Responses to Code Control commands are optional and set via the Programming
menu.
4.4 Lead Control of Ports
The Remote Management Switch can automatically select ports via control leads.
You must set up this feature before using the switch. Any port can access the
master by raising the RTS or DTR lead (jumper selectable) provided no other port
is already connected by Menu, Manual, or Code Control. If another port is
connected, the request is placed in queue. The queue is first-in, first-out.
Once a port has been connected via lead control, it remains connected until the
control lead has gone low. If a port has been manually selected, and another port
requests access, the manually selected port remains active until it is deselected via
Menu, Code, or Manual Control.
4.5 Manual Control of Ports
You can control the switch manually via the pushbutton switch on the front panel
(provided that anyone who has been controlling the switch remotely has exited the
remote menu). Each time you press the button, the port will cycle to the next port.
To return the Switch to automatic operation, press the pushbutton switch for over
two seconds. All port LEDs will turn off.
The Timeout feature, if enabled, continues to operate when manual control is
established. To override this feature, select Timeout=0 from the Programming
menu.
When manual control is selected, lead control is locked out. Escape codes will
override the manual selection only in terminal mode.
