CHAPTER 2: PRODUCT OVERVIEW
23
• SAM module – a standard Octet server access module that connects a target device to
the switching system. SAM modules are available for PS/2, USB and Sun VGA or
13W3 interfaces.
• SAMDM module –a two-port Octet server access module that enables one server to
be shared between two Octet switches, increasing the number of users that can be
added to the switching system. The SAMDM module also enables the multimedia
feature (audio and serial data communication) when it is connected to a user station
that supports this feature. SAMDM modules are available as PS/2, USB and Sun
VGA interface modules.
• Serial SAM (serial) module – a DCE (Data Communication Equipment) device that
is the primary interface between a serial device and the Octet switching system. It
supports VT100 terminal emulation, break suppression and port history. See Chapter
6 beginning on page 89 for more information.
Octet server access modules are connected to the switching system with UTP cabling and
eliminate the need for additional cables or extra rack spaces. Each Octet server access
module has a factory-assigned unique number that identifies the attached target device
within the system.
UTP cables
You may use any combination of CAT 5, CAT 5e and CAT 6 cables in the Octet
switching system.
NOTE:
Throughout this manual, UTP refers to any CAT cable used by the Octet switching system.
2.4 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 mm2 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.
