Cisco ONS 15454 Installation and Operations Guide
November 2001
Chapter 1 Hardware Installation
Fiber-Optic Cable Installation
Procedure: Remove a Gigabit Interface Converter
Step 1 Disconnect the network fiber cable from the GBIC SC connector.
Step 2 Release the GBIC from the slot by simultaneously squeezing the two plastic tabs (one on each side of
the GBIC).
Step 3 Slide the GBIC out of the Gigabit Ethernet module slot.
A flap closes over the GBIC slot to protect the connector on the Gigabit Ethernet card.
1.13 Fiber-Optic Cable Installation
This section explains how to install optical fibers on OC-N cards.
Caution Always use the supplied ESD wristband when working with a powered ONS 15454. Plug the
wristband cable into the ESD jack located on the lower-right outside edge of the shelf assembly.
ONS OC-N cards feature SC connectors. To install fiber-optic cables in the ONS 15454, a fiber cable
with the corresponding connector type must be connected to the transmit and receive ports on the ONS
15454 cards. On ONS 15454 optical card ports, the top connector is transmit and the bottom connector
is receive. Cisco recommends that the transmit and receive and the working and protection fibers be
labeled at each end of the fiber span to avoid confusion with cables that are similar in appearance.
For information about fiber cable management, see the “Optical Cable Management” section on
page 1-55.
Warning
Class I (21 CFR 1040.10 and 1040.11) and Class 1M (IEC 60825-1 2001-01) laser products.
Warning
Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector.
Do not stare into the beam or view directly with optical instruments. Viewing the laser output with
certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a
distance of 100 mm may pose an eye hazard. Use of controls or adjustments or performance of
procedures other than those specified may result in hazardous radiation exposure.
Warning
The laser is active when the card is booted and the safety key is in the on position (labeled 1). The
port does not have to be in service for the laser to be on. The laser is off when the safety key is off
(labeled 0).
Warning
Follow all directions and warning labels when working with optical fibers. To prevent eye
damage, never look directly into a fiber or connector.
