SAFETY INSTRUCTIONS
To ensure reliable and safe long-term operation of your Repeater please note the following guidelines.
INSTALLATION
Only use in dry, indoor environments.
The Repeater and the power supply units can get warm. Do not install components in an enclosed space without any airflow.
Do not place the power supply directly on top of the device.
Do not obscure ventilation holes.
Only use power supplies originally supplied with the product or manufacturer-approved replacements. Do not use a power supply if
it appears to be defective or has a damaged chassis.
Connect all power supplies to grounded outlets. In each case, ensure that the ground connection is maintained from the outlet
socket through to the power supply’s AC power input.
Do not connect the link interface to any other equipment, particularly network or telecommunications equipment.
Take any required ESD precautions.
NOTE: To disconnect the device completely from the electric circuit, all power cables have to be removed.
REPAIR
Do not attempt to open or repair a power supply unit.
Do not attempt to open or repair the Repeater. There are no user serviceable parts inside.
Please contact Black Box Technical Support at 877-877-2269 or [e-mail] if there is a fault.

CHAPTER 1: SPECIFICATIONS
1.1 INTERFACES
1.1.1 RJ-45 (INTERCONNECT)
For CATx communications, the repeater requires a 1000BASE-T connection.
Connector wiring must comply with EIA/TIA-568-B (1000BASE-T), with RJ-45 connectors at both ends. All four cable wire pairs
are used.
1.1.2 FIBER SFP TYPE LC (INTERCONNECT)
The communication of fiber devices is performed via Gigabit SFPs that have to be connected to suitable fibers fitted with type LC
connectors.
NOTE: The correct function of the device can only be guaranteed with SFPs provided by Black Box.
CAUTION: SFP modules can be damaged by electrostatic discharge (ESD). When handling, take care not to damage devices.
1.2 INTERCONNECT CABLE
1.2.1 C AT X
NOTE: A point-to-point connection is required. Operation with several patch fields is possible. Routing over an active network component,
such as an Ethernet hub, router, or switch, is not allowed.
Avoid routing CATx cables along power cables.
If the site has 3-phase AC power, make sure that the CPU module and CON module are on the same phase.
CAUTION: To maintain regulatory EMC compliance, you must use correctly installed shielded CATx cable throughout the interconnection
link. Also, all CATx cables need to have ferrites on both cable ends close to the device.
TYPE OF INTERCONNECT CABLE
The (Cross) Repeater requires interconnect cabling specified for Gigabit Ethernet (1000BASE-T). The use of solid-core (24 AWG), shielded,
CAT5e (or better) is recommended.
TABLE 1-1. CATX INTERCONNECT CABLE
CABLE TYPE DESCRIPTION
CATx solid-core cable 24 AWG S/UTP (CAT5e) cable according to EIA/TIA-568-B. Four pairs of 24 AWG wires. Connection according
to EIA/TIA-568-B (1000BASE-T).
CATx patch cable 26/8 AWG S/UTP (CAT5e) cable according to EIA/TIA-568-B. Four pairs of 26/8 AWG wires. Connection according
to EIA/TIA-568-B (1000BASE-T).
NOTE: You can use flexible cables (patch cables) type 26/8 AWG; however, but you’ll only get half the maximum possible extension distance
(Table 1-2).

CHAPTER 2: DESCRIPTION
2.1 APPLICATION
The (Cross) Repeater is used to double the maximum cabling distance between a KVM extender CON or CPU Unit or even a KVM
matrix. The device can also be used for media conversion from CATx to fiber or vice versa.
The device is available as a pure CATx or fiber version (repeater) and as a hybrid version of CATx and fiber (cross repeater) for an
additional electrical/optical signal conversion.
2.2 SYSTEM OVERVIEW
The (Cross) Repeater consists of at least one module depending on the application.
The device is connected between a KVM extender CON and CPU Unit via the interconnect cable or can be alternatively connected
between a KVM extender unit and a KVM matrix.
The (Cross) Repeater communicates with both the KVM extenders and a KVM-Matrix via the interconnect cables.
