Dominion SX Frequently Asked Questions 4/9
Question
Answer
What is the MTBF for the power
supply in the Dominion SX?
350,000 hours. But, keep in mind that the life of a power supply depends on
environmental factors like temperature, humidity, variation in power, and other
factors.
What is the ESD (electro-static
discharge) protection on the
Dominion SX serial ports?
15KV (Kilo volts)
Why do I need to use a serial
adapter to connect to some
servers?
While EIA published a standard for RS232 on DB25 and DB9 connectors,
there is no standard for RS232 on RJ45 connectors. Also, some
manufacturers have chosen not to follow the pin out assignments of the EIA on
DB25 and DB9 connectors.
Is the Dominion SX unit SUN®
"break-safe"?
All Dominion SX units are SUN "break-safe" for use with SUN Solaris, and the
units are Solaris Ready certified by SUN.
I have lost my Admin password
to the Dominion SX. Is there a
back door or secret password?
For security reasons, there is no back-door password. The only option is to
restore the unit to its factory default settings. A hardware reset function to
restore the unit to factory default settings is provided.
Does Dominion SX include the
19" rack mount kit or is there an
extra charge for this option?
Dominion SX comes standard with a complete ready-to-install 19" rack mount
kit on the models with 16 or greater serial ports. One 8-port model with dual-
power also comes with a rack-mount kit. Some competitors charge extra for a
rack mount kit. On models with less than 16 ports, a rack mount kit is available
as an option.
What remote access connection
methods can Dominion SX
accommodate?
Dominion SX provides multiple choices for remote access. These include:
HTTP/HTTPS, SSH/Telnet, or dial-up modem. That means servers can be
accessed both in and out of band so remote access to mission critical target
servers is always available-even if the network is down.
Which ports need to be open on
the corporate firewall for a
secure console session using
Dominion SX?
Port 443 (for https); optionally port 80 (http) for user sessions. For units
running software version 2.2 or higher, port 51000 (or other port between
1024-65536). On software releases PRIOR to firmware 2.2 (2.0Bx or 2.1.x)
either port 23 or a user-designated port between 2000 and 2400. When using
SSH, port 22 needs to be open. Starting with Dominion SX firmware 3.0, the
TCP ports for HTTP, HTTPS, Telnet, SSH are all user configurable. These
user configured ports will need to be open for access. Also, TCP port 5000.
How do I get access to the
operating system of the
Dominion SX?
Dominion SX is a secure appliance. Therefore, NO access is possible to the
operating system.
I have a few serial devices
located a distance away from my
server closet and the Dominion
SX. Can I connect these devices
to my Raritan switch?
Yes. EIA RS232 specifications defined in the 1970s recommend that the
maximum distance serial devices be 10 meters. However, with good cables,
no patch panels, and lower baud rates, customers report success up to 60
meters.
How do I upgrade the software
on my Dominion SX?
Use the Administrator option for Upgrade from a menu. The upgrade is done
over the Ethernet port of the Dominion SX. Access to an FTP server is
required.
Are updates to Dominion SX
software free?
Yes. Currently, all software upgrades are free.
Does Dominion SX require any
additional client software?
No. Dominion SX is truly "Plug-and-Play" making installation quick and set-up
easy. It is not necessary to buy any additional client software or hardware. In
addition, no special networking equipment or design is necessary.
