Installation Instructions
Secure Racking
If Secure Racked units are installed in a closed or multi-unit rack assembly, they may require
further evaluation by Certification Agencies. The following items must be considered.
1. The ambient within the rack may be greater than room ambient. Installation should be such
that the amount of air flow required for safe operation is not compromised. The maximum
temperature for the equipment in this environment is 45°C. Consideration should be given to
the maximum rated ambient.
2. Installation should be such that a hazardous stability condition is not achieved due to uneven
loading.
Input Supply
1. Check nameplate ratings to assure there is no overloading of supply circuits that could have an
effect on overcurrent protection and supply wiring.
2. When installing 48 VDC rated equipment, it must be installed only per the following
conditions:
A. Connect the equipment to a 48 VDC supply source that is electrically isolated from the
alternating current source. The 48 VDC source is to be connected to a 48 VDC SELV
source.
B. Input wiring to terminal block must be routed and secured in such a manner that it is
protected from damage and stress. Do not route wiring past sharp edges or moving parts.
C. A readily accessible disconnect device, with a 3 mm minimum contact gap, shall be
incorporated in the fixed wiring.
Grounding
Reliable earthing of this equipment must be maintained. Particular attention should be given to
supply connections when connecting to power strips, rather than direct connections to the branch
circuit.
No Serviceable Parts Inside; Authorized Service Personnel Only
Do not attempt to repair or service this device yourself. Internal components must be serviced by
authorized personnel only.
• Shock Hazard - Do Not Enter
• Lithium Battery
CAUTION: Danger of explosion if battery is incorrectly replaced. Replace only with same
or equivalent type recommended by the manufacturer. Discard used batteries according to
the manufacturer's instructions.
Disconnect Power
If any of the following events are noted, immediately disconnect the unit from the outlet and
contact qualified service personnel:
1. If the power cord becomes frayed or damaged.
2. If liquid has been spilled into the device or if the device has been exposed to rain or water.

RSM Series; Remote Site Managers - User’s Guide
1-1
1. Introduction
The RSM-8, RSM-16, RSM-16DC, RSM-32 and RSM-32DC Remote Site
Managers provide in-band and out-of-band access to RS-232 console ports and
maintenance ports on UNIX servers, routers and any other network element
that includes a serial console port. System administrators can access the RSM
via TCP/IP network, using SSH or Telnet, or out-of-band via modem or local
terminal. The RSM features two separate command interfaces; a convenient,
user-friendly web browser interface, and a simple, command driven text
interface.
Intelligent Port Selection
Each of the RSM’s RS232 serial ports can be individually accessed by
number, name or group via SSH or Telnet sessions. The RSM also allows
direct connections using TCP port assignments. Each RSM serial port can
be separately configured using simple menu driven commands to set the port
password, data rate, flow control and other operating parameters.
The full matrix capability of the RSM allows you to easily connect any two
ports on the switch, even when the ports are using different communications
settings. Ports can also be connected or disconnected by a third party with
supervisor rights, and system managers can swap various RS232 devices
between ports at a remote location.
Security and Collocation Features
Secure Shell (SSHv2) encryption and address-specific IP security masks
prevent unauthorized access to command and configuration functions. The
RSM also provides two different levels of user security; the Supervisor level
and the Non-Supervisor level. The Supervisor level, which is intended for
use by system managers and other administrators, provides complete access
to all RSM port connection / disconnection functions, operating features and
configuration menus, and also allows access to any port on the switch. The
Non-Supervisor level is ideal for collocation applications, since users are only
permitted to view status and connect to the ports allowed by their password.
Capture Buffer
"Buffer Mode" allows individual ports to capture and store incoming data,
such as error and status messages received from attached console ports. This
"snapshot" of the last data received is stored in memory, and can be viewed,
saved, or erased by the system operator at any time. Console messages can be
stored in the RSM port buffers, and sent to a remote location via SYSLOG, or
an SNMP message can be generated to alert administrators when new console
messages are received.

Configuration Backup
Once you have configured the RSM to fit your application, parameters and
options can be saved to an ASCII text file on your PC. This allows you to
quickly restore user-selected parameters if unit configuration is accidentally
altered or deleted. Saved parameters can also be uploaded to other RSM units.
This allows rapid set-up when several units will be configured with identical or
similar parameters.
RSM-8, RSM-16, RSM-16DC, RSM-32 and RSM-32DC Units
This User’s Guide discusses five different models from our RSM product line:
the RSM-8, RSM-16, RSM-16DC, RSM-32 and the RSM-32DC. Throughout
this User's Guide, all of these units are referred to as the "RSM." Note
however that these units differ as described below:
• RSM-8: 8 Serial Ports, 100 to 240 VAC, 50/60 Hz, 5 Watts
• RSM-16: 16 Serial Ports, 100 to 240 VAC, 50/60 Hz, 5 Watts
• RSM-16DC: 16 Serial Ports, -48 VDC
• RSM-32: 32 Serial Ports, 100 to 240 VAC, 50/60 Hz, 5 Watts
• RSM-32DC: 32 Serial Ports, -48 VDC.
Aside from the differences listed above, all other features function identically
in all five models.
