LED and the ACT/STBY LED flash alternately every 30 to 45 seconds as the new software loads onto
the new TCC-I card. After the new card loads the software for approximately 30 minutes, it becomes
the standby card and the amber LED is illuminated.
Procedure: Install Optical, Electrical, and Ethernet Cards
Although the installation procedure is the same for optical, electrical, and Ethernet cards, you must
install the optical cards before installing the electrical cards.
Caution Before installing an OC192 LR/STM64 LH 1550 card, make sure the safety key on the faceplate is
in the off position (labeled 0). When the safety key is in the on position (labeled 1), the laser is
activated.
Warning
Invisible laser radiation can 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 can pose an eye hazard. Use of controls or adjustments or performance of
procedures other than those specified can result in hazardous radiation exposure.
Caution Hazardous voltage or energy may be present on the backplane when the system is operating. Use
caution when servicing.

Step 2 Slide the card along the guide rails into the correct slot.
Step 3 Close the ejectors.
