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.

Page 2: Cabling Requirements
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. - Page 3 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 •...
- Page 4 A/B Port Cards 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.
