SRM-100
The SRM-100 Secure Rack Modem provides password-protected, dial-in access to rack
mounted serial communications equipment. The SRM's non-volatile memory can store
up to 100 menu-defined passwords, each with an optional dial back number. The unit
can also track access activity for each password and create a log record of successful
and unsuccessful connection attempts.
Password Protected Access
Each menu-defined password can be assigned an individual User Name for easy reference,
and an optional Dial Back number, which instructs the unit to call the user at a predefined
number before allowing access to the secure device. A separate System Password restricts
access to the SRM Command Mode. This allows the system administrator to contact the
unit via modem in order to change parameters or check access activity.
Access Activity Logs
The SRM-100 provides two convenient ways to track access activity; the Connection Log
and the Password Directory. The Connection Log lists the 100 most recent connection
attempts, along with the password entered, port used, time, date, call duration, and status
at disconnect. The Password Directory displays all user names, passwords, and dial back
numbers, and also lists the number of times that each password has been used. The
Connection Log and Password Directory can only be viewed by the System Administrator;
callers who log on with a User Password are not allowed to view these screens.
Local or Remote Configuration
All configuration tasks are performed via the SRM's command mode. The command mode
features a series of command-driven configuration menus, which are used to select port
parameters, define passwords and dialback numbers, and review connection activity. The
command mode can be accessed locally via a serial DB9 Console Port, or remotely via
dial-up connection. This makes remote installation a breeze. Simply plug in the power
and phone line, and the system administrator can call the SRM and download all parameters,
either by keystroke or ASCII file.
In addition to allowing command mode access by a local system administrator, the SRM's
Console Port can also be connected to a secondary serial device, such as a reboot switch.
Although most dial-in users are only allowed to access the primary device connected to
the SRM modem port, a remote administrator can also access a secondary device
connected to the console port in order to initiate reboot operations or take equipment off-
line.
AC and DC Powered Models
The SRM-100 is available in both 115/230 VAC
powered models and -48 VDC powered models.
The AC version features a self adjusting power
supply for 115/230 volt AC operation at 50/60
Hz. The -48 volt DC version is ideal for remote
locations where AC power may not be available.
The DC version features a dual bus terminal
block assembly, allowing easy connection to a
back-up power source.
Local or Remote Configuration
AThe SRM-100 provides three distinct operating
modes:
User Mode: Provides password protected
access to the secure device connected to the
SRM's serial modem port.
Command Mode: Provides password
protected access to the SRM command menus,
which are used to define passwords and select
configuration parameters. When accessed via
modem, the command mode also allows access
to an optional secondary device installed at the
SRM console port.
Unsecured Mode: If necessary, the SRM's
security features can also be disabled. When
security is disabled, the SRM will function like
a normal, unsecured, rack modem; callers are
allowed to access the secure device without
entering a password.
