Quick Setup Guide Quick Setup Guide This section briefly describes how to install your ServSwitch CWDM Mux system. Unless you are an experienced user, we recommend that you follow the full procedures described in the rest of this manual. Install system 1. Install the ServSwitch CWDM Mux transceivers in the local and remote units. Each wavelength must not appear more than once in the system. Device pairs must carry transceivers with the same wavelength. 2. Connect interconnection cables from remote/local unit to the ServSwitch CWDM Mux make sure you connect the transceivers to the matching port of the ServSwitch CWDM Mux. Be sure to use single-mode fiber cable between the local and remote units via the common link. 3. Power on the system. Check the fiber cables and fiber connectors. Link established? YES NO Check whether the transceivers are plugged into the correct ports. 1530-µm lightwave transceivers should plug into 1530-µm ports, 1550-µm transceivers should plug into 1550-µm ports, and so on.

Chapter 2: Overview 2. Overview 2.1 Introduction The ServSwitch CWDM Mux breaks away from the traditional model of using fiber interconnection cables. With the ServSwitch CWDM Mux, you can send up to four bidirectional data streams simultaneously over a single pair of fiber cables. Wherever you run low on installed fibers or when you want to avoid installing new fibers, you can use the ServSwitch CWDM Mux. It s suitable for all kinds of single-mode fiber cables. It works with matching CDWM transceiver modules with wavelengths of 1530, 1550, 1570, or 1590 nm. A ServSwitch CWDM Mux reduces the number of required fibers for a number of independent data links. The ServSwitch CWDM Mux mixes the signals in different wavelengths onto a single fiber and splits it again into the original signals at the end of a link. A basic ServSwitch CWDM Mux system consists of a local KVM extender unit and a remote KVM extender unit. 2.2 Features The ServSwitch CWDM Mux offers the following features: Support for up to four data streams. Support for 9-μ single-mode fibers. No power supply unit is required. Small footprint chassis. Rackmountable. 2.3 What s Included Your package should include the following items. If anything is missing or damaged, contact Black Box Technical Support at 724-746-5500 or info@blackbox.com.

ServSwitch CWDM Mux 3. Installation For first-time users, we recommend that you carry out a test placement, confined to a single room, before commencing full installation. This will help you to identify and solve any cabling problems, and experiment with the KVM extender system more easily. 3.1 Interconnection Cable Requirements To connect the local and remote ACS4001A-R2-SM units to the ServSwitch CWDM Mux box and to interconnect the ServSwitch CWDM Mux boxes, you ll need: Fiber cable: Two strands of fiber are required for connecting the local and remote ACS4001A-R2-SM units to the ServSwitch CWDM Mux box and to interconnect both Mux/Demux boxes. Recommended cables: Single-mode type 9/125 μ. Maximum cable length: Approximately 25 miles (40 km). 3.2 System Setup To install your ServSwitch CWDM Mux system: 1. Switch off all devices. 2. Install the ServSwitch CWDM Mux Transceivers in the local and remote CWDM Mux units. Each wavelength must not appear more than once in the system. Device pairs must carry transceivers with the same wavelength. NOTES: Each wavelength (1530, 1550, 1570, 1590 nm) must not be used more than once at each side! For four links, use four different wavelengths; for three links, use three different wavelengths; and for two links, use two different wavelengths. Each transceiver will work only at the appropriate port. The data will always flow between devices with the same wavelengths. 3. Connect interconnection cables from the remote/local ACS4001A-R2-SM unit to ServSwitch CWDM Mux make sure that you connect the transceivers to the matching port at the ServSwitch CWDM Mux. 4. Connect local and remote ServSwitch CWDM Mux units with matching interconnection cable (single-mode fiber). 5. Power on the system. 3.3 Diagnostics There are no diagnostics on the ServSwitch CWDM Mux. Please use the capabilities of the attached units. Page 12 724-746-5500 blackbox.com

Chapter 4: Troubleshooting 4. Troubleshooting 4.1 Problem/Solutions Problem: There isn t a data link. Possible Causes/Solutions: 1. Check the attached devices by directly connecting the local unit to the remote unit using a short fiber cable. 2. Check that each wavelength does not occur more than once at the local side and at the remote side. 3. Check that the transceivers are routed to the correct ports on the ServSwitch CWDM Mux. 4.2 Contacting Black Box If you determine that your unit is malfunctioning, do not attempt to alter or repair it. It contains no user-serviceable parts. Contact Black Box Technical Support at 724-746-5500 or info@blackbox.com. Before you do, make a record of the history of the problem. We will be able to provide more efficient and accurate assistance if you have a complete description, including: The nature and duration of the problem. When the problem occurs. The components involved in the problem that is, what type of computers, what type of keyboard, brand of mouse, make and model of monitor, type and make of cable, etc. Any particular application that, when used, appears to create the problem or make it worse. The results of any testing you ve already done. 4.3 Shipping and Packaging If you need to transport or ship your unit: Package it carefully. We recommend that you use the original container. If you are shipping it for repair, please include the ServSwitch CWDM Mux s external power supplies. If you are returning it, please include everything you received with it. Before you ship the unit back to your Black Box for repair or return, contact us to get a Return Authorization (RA) number. 724-746-5500 blackbox.com Page 13
