Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when
electronic components are improperly handled and can result in complete or intermittent failures.
Always follow ESD-prevention procedures when removing and replacing components. Ensure that
the chassis is electrically connected to earth ground using an ESD mat or a ground wire. Wear an
ESD-preventive wrist strap, ensuring that it makes good skin contact. To safely channel unwanted
ESD voltages to ground, connect the clip to the surface of an unpainted chassis frame. To properly
guard against ESD damage and shocks, the wrist strap and cord must operate effectively. If no wrist
strap is available, ground yourself by touching the metal part of the chassis.
Caution For safety, periodically check the resistance value of the antistatic strap, which should be
between 1 and 10 mega ohms.
About this Publication
This publication includes the procedures required to install Copper Distributed Data Interface
multilevel transmission (CDDI/MLT-3) and Fiber Distributed Data Interface (FDDI) A/B port cards
in the workgroup switch and concentrator models that use this card. The equal sign (=) appended to
the product numbers designates these products as spare parts.
Following are the sections and procedures included:

2 Installing A/B Port Cards
Cabling Requirements
Cabling Requirements
Following are the cabling requirements for the A/B port cards.
FDDI The multimode FDDI connectors on the switch accept 62.5/125-micron or 50/125-micron
multimode fiber with standard FDDI media interface connectors (MICs). The single-mode
connectors accept 8.7 to 10/125-micron single-mode fiber with standard FDDI ST-type connectors.
Table 1 lists FDDI distance specifications and Figure 1 and Figure 2 illustrate single-mode and
multimode connectors, respectively.
Table 1 FDDI Maximum Transmission Distances
Figure 1 Single-Mode FDDI Interface Connector—ST Type
Warning Invisible laser radiation may be emitted from the aperture ports of the single-mode FDDI
card when no cable is connected. Avoid exposure and do not stare into open apertures.
Figure 2 Multimode FDDI Interface Connector—MIC Type
CDDI Check all existing cables to ensure that you have the proper connectors (modular RJ-45) and for
conformance with the following CDDI/MLT-3 distance requirements and:
•Data-grade unshielded twisted-pair (UTP) wiring—Electronics Industries
Association/Telecommunications Industries Association (EIA/TIA)-568 category 5, data-grade
cableisrequiredforCDDIinstallations.ThetotallengthofdatagradeUTPcablefromtheswitch
to another switch, station, or CDDI concentrator must not exceed 330 feet (100.6 m), including
patch cords and cross-connect jumpers.
•Shielded twisted-pair (STP) wiring—You must use IBM Type 1 STP wiring for your CDDI
installation. The total length of STP cable measured from the adapter or media access unit
(MAU) to the switch must not exceed 330 feet (100.6 m).
Transceiver Type Maximum Distance Between Stations
Single-mode 18.6 miles (up to 30 km)
Multimode 1.2 miles (up to 2 km)

Note You must use high-performance, category 5, data-grade, modular cross-connect cables for
external CDDI connections.
When you plan your CDDI installation, remember the following:
•Use cross-connect (patch) panels which comply with the EIA/TIA 568B category 5 wiring
standard.
•Do not use bridge taps.
•Do not use protection coils.
•Do not share services (such as voice and data on the same cable). CDDI uses two of the four pairs
in the twisted-pair cable. The remaining two pairs cannot be used for other applications.
•Do not exceed the maximum cable length for CDDI UTP and STP of 330 feet (100.6 m).
A/B Port Cards
The A/B port cards are options that provide two additional CDDI/MLT-3 or FDDI ports.
Caution During these procedures, the concentrator must be turned off, thereby disrupting the ring.
The A/B card slot supports a single media access control (MAC), dual attachment station (DAS)
with dual homing configuration for FDDI (can also be used as single attachment station [SAS]). The
slot also accepts CDDI/MLT-3 cards for UTP and STP connections.
Figure 3 shows the following three models of A/B port cards:
•WS-C1511—Multimode FDDI with FDDI MICs
•WS-C1513— CDDI/MLT-3 with category 5 UTP modular RJ-45 connectors
•WS-C1514—Single-mode FDDI with standard FDDI ST-type connectors

Port Card Installation
Following is the procedure for installing an A/B port card:
Step 1 Unplug the power cable but, to channel ESD voltages to ground, ground the chassis and
attach an ESD-preventive wrist strap.
Caution To prevent damage, never install or remove a port card with power applied to the
concentrator.
Step 2 Remove the two screws holding the blank plate to the concentrator and remove the plate.
Caution To prevent damage to the FDDI transceivers on the FDDI port card (in step 3), gently press
down on the port card as you insert it so that the transceivers clear the chassis. The fit is snug.
Step 3 Slide the port card into the slot in the concentrator. Make sure the metal base plate on the
card slides under the guides in the concentrator. (See Figure 4.)
Step 4 Secure the card to the concentrator using the two Phillips screws supplied with the port
card.
Step 5 Reinsert the power cable.

Port Card Removal
Following is the procedure for removing an A/B port card:
Step 1 Unplug the power cable but, to channel ESD voltages to ground, ground the chassis and
attach an ESD-preventive wrist strap.
Caution To prevent damage, never install or remove a port card with power applied to the
concentrator.
Step 2 Remove the two screws that secure the port card to the concentrator. (See Figure 5.)

Caution To prevent damage to the FDDI transceivers on the FDDI port card (in step 3), gently press
down on the port card as you remove it so that the transceivers clear the chassis. The fit is snug.
Step 3 Gently pry the A/B port card out of the slot with a flat-blade screwdriver. (See Figure 5.)
After traveling approximately 1/2 inch, the card will be free from the connector and will
slide out easily.
Step 4 Reinsert the power cable.
