Cisco ONS 15454 SDH Installation and Operations Guide, R3.3
May 2002
Chapter 1 Hardware Installation
Card Installation
ONS 15454 SDH cards have electrical plugs at the back that plug into electrical connectors on the shelf
assembly backplane. When the card ejectors are fully closed, the cards plug into the assembly backplane.
Figure 1-14 shows card installation.
Caution Always use the supplied ESD wristband when working with an ONS 15454 SDH. Plug the wristband
cable into the ESD jack located on the middle-right outside edge of the shelf assembly.
Warning
During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not
directly touch the backplane with your hand or any metal tool, or you could shock yourself.
Warning
Class-I (21 CFR 1040.10 and 1040.11) and Class-1M (IEC 60825-1 2001-01) laser products.
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 The laser of the OC-192 LR/STM64 LH 1550 is active when the card is booted and the safety key is
in the on position (labeled 1). The port does not need to be in service for the laser to be active. The
laser is off when the safety key is in the off position (labeled 0).
Caution Hazardous voltage or energy may be present on the backplane when the system is operating. Use
caution when servicing.
