CHAPTER 2: INTRODUCTION
23
The Octet Serial SAM is a DCE (Data Communication Equipment) device that provides
the primary interface between a serial device and the Octet switching system.
It supports VT100 terminal emulation, break suppression and port history in a convenient
module format. For information on using the Serial SAM, refer to Chapter 7.
These modules eliminate the need for extra rack spaces or additional cables. For ease of
installation, each SAM has a factory-assigned unique number that identifies the attached
server within the system. The connection between the Octet switching system and these
modules is through industry standard UTP cabling.
UTP cables
The Octet switching system uses video technologies that compensate for the losses that
occur in all UTP cables. These technologies make the Octet switch compatible with most
UTP cable types and support Octet switch use in environments where there are
combinations of UTP cable types and patch panels. The Octet switch will function
correctly with any combination of CAT 5, CAT 5e and CAT 6 cables.
NOTE: Throughout this manual, the generic term UTP refers to any CAT cable used by the Octet
switching system.
2.3 Safety Precautions
To avoid potential video and/or keyboard problems when using Black Box products:
•
If the building has 3-phase AC power, ensure that the server and monitor are on the
same phase. For best results, they should be on the same circuit.
To avoid potentially fatal shock hazard and possible damage to equipment, please observe
the following precautions:
•
Do not use a 2-wire extension cord in any Black Box product configuration.
• Test AC outlets at the server and monitor for proper polarity and grounding.
• Use only with grounded outlets at both the server and monitor. When using a backup
Uninterruptible Power Supply (UPS), power the server, the monitor and the Octet
switch off the supply.
NOTE:
The AC inlet is the main disconnect.
DC installation safety considerations
As a safety precaution, install this product in an area with limited or controlled access. A
readily accessible disconnect device that is suitably approved and rated shall be
incorporated in the field wiring. Connect field wiring from earth ground to the screw
terminal marked with the ground symbol. Terminals will accommodate wiring from 26 to
12 AWG (up to 2.5 mm
2
maximum cross section). Strip each wire, insert it in the square
opening in the terminal block and tighten the screw above it to a maximum of 70 ounce-
inches (0.5 Nm) using either a flat or Phillips-head screwdriver.
Rack mount safety considerations
• Elevated Ambient Temperature: If installed in a closed rack assembly, the operation
temperature of the rack environment may be greater than room ambient. Use care not
to exceed the rated maximum ambient temperature of the unit.
