Cisco ONS 15454 Procedure Guide, R5.0
May 2006
Chapter 2 Install Cards and Fiber-Optic Cable
NTP-A16 Install the OC-N Cards
Warning
Class I (CDRH) and Class 1M (IEC) laser products.
Statement 1055
Warning
Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector.
Do not stare into the beam 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 could pose an eye hazard.
Statement 1056
Warning
Use of controls, adjustments, or performing procedures other than those specified may result in
hazardous radiation exposure.
Statement 1057
Warning
On all OC-N cards except the OC192 LR/STM64 LH 1550 card, the laser is on even when the optical port
is not in service.
Warning
On the OC-192 card, the laser is on 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).
Statement 293
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.
Note If protective clips are installed on the backplane connectors of the cards, remove the clips before
installing the cards.
Note To simplify path protection to bidirectional line switched ring (BLSR) conversion and node addition,
install OC-N cards according to a high-speed east (Slots 12 and 13) and west (Slots 5 and 6)
configuration. This configuration is not mandatory.
Note If you install a card incorrectly, the FAIL LED flashes continuously.
Note During the boot process, an out-of-service (OOS) OC-N port will output a Line Alarm Indication Signal
(AIS-L) to any in-service (IS) far-end receivers. See the Cisco ONS 15454 Troubleshooting Guide for
further information about the AIS-L condition.
Step 1 If you installed XC or XCVT cards, review Table 2-1 on page 2-3 to determine card/slot compatibility.
If you installed XC10G cards, review Table 2-2 on page 2-5 to determine card/slot compatibility.
