1 About HP CWDM MUX modules and CWDM (SFP) transceivers This chapter includes information about: • “HP CWDM MUX modules” on page 11 • “CWDM (SFP) transceivers” on page 16 HP CWDM MUX modules This section includes information about: • “HP CWDM 8-port Multiplexer/Demultiplexer module” on page 11 • “HP CWDM Slot A 4-port and HP CWDM Slot B 4-port Add/Drop MUX modules” on page 12 • “Supported configurations using HP CWDM MUX modules” on page 12 HP CWDM MUX modules are Coarse Wave Division Multiplexer (CWDM) pa
• One monitor port, also known as tap port, optionally used to connect optical monitoring equipment for checking optical link quality • One network port to allow users to connect to additional CWDM modules to extend their SAN or network • Dual LC-type connectors for all optical connections Figure 1 HP StorageWorks CWDM 8-port Multiplexer/Demultiplexer module HP CWDM Slot A 4-port and HP CWDM Slot B 4-port Add/Drop MUX modules The CWDM Slot A 4-port Add/Drop Multiplexer (Figure 2) and CWDM Slot B 4-port Ad
gigabits of data from one location to another. Typical applications include linking two data centers to become one virtual site, mirroring two sites for disaster recovery, or providing a large amount of bandwidth between two buildings. Each HP CWDM MUX supports one network backbone connection and four or eight connections to CWDM (SFP) transceivers in the locally-attached Fibre Channel Storage Area Network (FC SAN) or Ethernet network equipment.
Figure 5 Point-to-point: 4-port (non-redundant) Figure 6 Point-to-point: 8-port to 4-port (non-redundant) Point-to-point redundant configurations (no single point of failure) Typically, for redundant configurations, two HP CWDM 8-port MUX modules are installed in a chassis. Two HP CWDM Slot A 4-port Add/Drop MUX modules or two HP CWDM Slot B 4-port Add/Drop MUX modules can be installed in a chassis for redundancy.
In Figure 7, Figure 8 and Figure 9, the HP CWDM MUX modules on the left are termed the West path and the modules on the right are termed the East path. This allows a point-to-point connection, so that the network will remain viable even if the fiber is broken at one point.
Figure 9 Point-to-point: 8-port to 4-port to 4-port (redundant, no single point of failure) CWDM (SFP) transceivers CWDM (SFP) transceivers are hot-swappable, field-replaceable, small form pluggable devices (Figure 10) that adapt an electronic data signal to laser light at a specific wavelength. These devices allow gigabit ports to link with fiber optic networks. CWDM (SFP) transceivers create light at one of eight specific wavelengths.
• Low power dissipation For a list of specific CWDM (SFP) transceivers and part numbers, see the HPwebsite www.hp.com/go/cwdm-mux CWDM (SFP) transceivers are color-coded to indicate the wavelength and have a color-coded clasp at one end. See Table 2 for the color codes and corresponding wavelengths.

2 Installing HP CWDM MUX modules The following hardware is required to install the HP CWDM MUX modules: • • • • • • HP StorageWorks CWDM 2-slot chassis HP StorageWorks CWDM 8-port Multiplexer/Demultiplexer HP StorageWorks CWDM Slot A/Slot B 4-port Add/Drop Multiplexer CWDM (SFP) transceivers Fiber optic cables Cage nuts and screws Preparing for installation Before installing the HP CWDM MUX modules, observe the following: • Environmental and physical requirements • Electrostatic discharge (ESD) warning E
• Avoid bringing synthetic materials such as polyester, plastic, vinyl, or styrofoam into the area where installation is being performed because these materials carry static electricity that may damage sensitive components. Mounting the equipment in a rack The HP CWDM 2-slot chassis can be mounted in a standard 19-inch cabinet or rack. To attach the chassis to a standard 19-inch rack: 1. Insert two cage nuts on each rail. 2.
• To clean contaminants from the optical bores of a CWDM (SFP) transceiver, use lint-free 1.25 mm Fiber Optic swabs to clean the ferrules of the optical connector. • Dispose of this product according to all national laws and regulations. NOTE: Dry cleaning is the preferred method. Using alcohol-based cleaning swabs may cause problems. WARNING! Fiber optic equipment can emit laser or infrared light that can injure your eyes. Never look into an optical fiber or connector port.
3. Slide the CWDM (SFP) transceiver out of the device module slot. NOTE: If your CWDM (SFP) transceiver does not slide easily from the module slot, use a gentle side-to-side rocking motion while firmly pulling the CWDM (SFP) transceiver out. 4. Put the dust covers securely on the CWDM (SFP) transceivers. Cabling HP CWDM MUX modules Connecting fiber optic cables from the HP CWDM MUX module ports to the CWDM (SFP) transceivers is simplified by color coding.
Figure 13 Cabling an HP CWDM Add/Drop MUX Module Connecting to the network There are two possible network configurations, using either two or three HP CWDM MUX modules: Two HP CWDM MUX configuration • For a two HP CWDM MUX module configuration, connect the network port of the first HP CWDM MUX module to the network port of the second HP CWDM MUX module. For non-redundant cabling, see Figure 4 and Figure 5. For redundant cabling, see Figure 7 and Figure 8.
