NTP-D19 Install Fiber-Optic Cables on Optical Cards
Warning
Class I (21 CFR 1040.10 and 1040.11) and Class 1M (IEC 60825-1 2001-01) laser products.
Statement 291
Warning
Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do
not 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.
Statement 1056
The following warning applies only to STM-64 cards with safety keys:
Warning
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
Do not use fiber loopbacks with the STM64 LH 1550 or STM64 LH ITU 15xx.xx card unless you are
using a 20-dB attentuator. Never connect a direct fiber loopback. Using fiber loopbacks causes
irreparable damage to the STM64 LH 1550 or STM64 LH ITU 15xx.xx card.
Caution
Do not use fiber loopbacks with the STM64 SH 1550 card unless you are using a 5-dB attentuator. Never
connect a direct, unattenuated fiber loopback. Using unattenuated fiber loopbacks causes irreparable
damage to the STM64 SH 1550 card.
Caution
Always use the supplied ESD wristband when working with a powered ONS 15454 SDH. Plug the
wristband cable into the ESD jack located on the lower-right outside edge of the shelf assembly.
Note
You can install the fiber immediately after installing the cards, or wait until you are ready to turn up the
network. See
Chapter 5, “Turn Up a Network.”
