1. Introduction
WTI’s RSM-8R series Remote Site Manager + Power Control units allow secure, remote
monitoring and management of AC powered rack mount equipment via SSL, SSH,
SNMP, web browser, telnet, internal modem or local terminal. The RSM-8R allows you
to connect to console ports on rack mounted devices, switch and reboot power, monitor
equipment temperature and can automatically notify you when changes in temperature
or response to ping commands exceeds user-defined threshold values.
Security and Co-Location Features:
Secure Shell (SSHv2) encryption and address-specific IP security masks help to prevent
unauthorized access to command and configuration functions.
The RSM-8R also provides four different levels of security for user accounts:
Administrator, SuperUser, User and ViewOnly. The Administrator level provides
complete access to all serial port and switched plug functions, status displays and
configuration menus. The SuperUser level allows control of serial ports and plugs, but
does not allow access to configuration functions. The User level allows access to only a
select group of Administrator-defined serial ports and plugs. The ViewOnly level allows
you to check unit status, but does not allow control of serial ports or switched outlets or
access to configuration menus.
The RSM-8R includes full Radius, LDAP and TACACS capability, DHCP and an invalid
access lockout feature. An Audit Log records all user access, login and logout times
and command actions, and an Alarm Log records user-defined alarm events.
Environmental Monitoring and Management:
The RSM-8R can constantly monitor temperature levels, ping response and other
factors. If the RSM-8R detects that user defined thresholds for these values have
been exceeded, the unit can promptly notify you via email, SNMP, or Syslog. When
temperature readings exceed user-defined critical values, the RSM-8R can also
intelligently decrease the amount of heat being generated within the rack by temporarily
shutting down nonessential devices; when readings return to acceptable levels, the
RSM-8R can restore power to those devices to return to normal operating conditions.
The RSM-8R also records temperature readings to a convenient log file.
If you need to switch power to rack mount devices at a specific time of the day or week,
the RSM-8R also includes a Scheduled Power Management feature, that allows you to
define a daily or weekly schedule for switching each outlet off or on, or even rebooting
that outlet.
The RSM-8R can also notify you when excessive invalid access attempts are detected,
and can automatically lock ports when it determines that an unauthorized user may be
attempting to gain access by "hammering" the unit with random passwords.

3.3. Communicating with the RSM-8R
When properly installed and configured, the RSM-8R will allow command mode access
via Telnet, Web Browser, SSH client, modem, or local PC. However, in order to ensure
security, both Telnet and Web Browser access are disabled in the default state. To
enable Telnet and/or Web Browser access, please refer to Section 5.9.2.
Notes:
• Default RSM-8R serial port parameters are set as follows: 9600 bps, RTS/
CTS Handshaking, 8 Data Bits, One Stop Bit, No Parity. Although these
parameters can be easily redefined, for this Quick Start procedure, it is
recommended to configure your communications program to accept the
default parameters.
• The RSM-8R features a default IP Address (192.168.168.168) and a default
Subnet Mask (255.255.255.0.) This allows network access to command
mode, providing that you are contacting the RSM-8R from a node on the
same subnet. When attempting to access the RSM-8R from a node that is
not on the same subnet, please refer to Section 5.9 for further configuration
instructions.
1. AccessCommandMode:The RSM-8R includes two separate user interfaces;
the Text Interface and the Web Browser Interface. The Text Interface is available
via Local PC, SSH Client, Telnet, or Modem and can be used to both configure the
RSM-8R and create connections between ports. The Web Browser interface is only
available via TCP/IP network, and can be used to configure the unit, but cannot
create connections between ports.
a) ViaLocalPC: Start your communications program and then
press [Enter].
b) ViaSSHClient: Start your SSH client, enter the default IP address
(192.168.168.168) for the RSM-8R and invoke the connect command.
c) ViaWebBrowser: Make certain that Web Browser access is enabled as
described in Section 5.9.2. Start your JavaScript enabled Web Browser, enter
the default RSM-8R IP address (192.169.168.168) in the Web Browser address
bar, and then press [Enter].

e) ViaModem: Use your communications program to dial the number for the line
connected to the RSM-8R’s Phone Line port.
2. Username/PasswordPrompt: A message will be displayed, which prompts you
to enter your username (Login) and password.. The default username is "super"
(all lower case, no quotes), and the default password is also "super". If a valid
username and password are entered, the RSM-8R will display either the Main Menu
(Web Browser Interface) or the Port Status Screen (SSH, Telnet, or Modem.)
3. ReviewHelpMenu: If you are communicating with the RSM-8R via the text
interface (SSH, Telnet or Modem), type /H and press [Enter] to display the Help
Menu, which lists all available RSM-8R commands. Note that the Help Menu is not
available via the Web Browser Interface.
3.4. Connecting Ports and Switching Outlets
Although both the Text Interface and Web Browser Interface allow you to select
configuration parameters, the Text Interface is always used when invoking commands to
connect ports. If you have previously accessed command mode via the Web Browser
Interface, exit command mode (log out), then re-enter command mode using the Text
Interface as described in Section 3.3.
Proceed as follows to connect ports and switch outlets:
1. ReviewtheHelpMenu: At the Text Interface command prompt, type /H and press
[Enter] to display the Help Menu, which provides a basic listing of all available
RSM-8R commands.
2. CreatingConnectionsBetweenPorts: The RSM-8R can perform two different
types of port connections; Resident Connections and Third Party Connections:
a) ResidentConnection: Your resident port issues a /C command to connect to
a second port.
i. To connect your resident port to Port 3, type /C 3 [Enter]. While you
are connected to Port 3, the unit will not recognize additional commands
issued via your resident port. However, the unit will recognize a Resident
Disconnect Sequence issued at either connected port.
ii. Issue the Resident Disconnect Sequence (Logoff Sequence); type ^X
(press [Ctrl] and [X] at the same time).
b) ThirdPartyConnection: Your resident port issues a /C command to create a
connection between two other ports.
i. To connect Port 3 to Port 4, type /C 3 4 [Enter].
ii. While Ports 3 and 4 are connected, your resident port will still recognize
commands. Type /S [Enter] to display the Status Screen. The "STATUS"
column should now list Ports 3 and 4 as connected and the other ports as
"Free".
