CLASS 1 LED PRODUCT.
In accordance with EN60825-1, Safety of Laser Products - Part 1: Equipment Class,
Requirements, and User's Guide (2001), single-mode IOAs with LC connectors are defined
as follows:
CLASS 1 LASER PRODUCT.
WARNING: Do not look directly into LC-style fiber connectors. The fiber-optic
laser used in single-mode fiber (SMF) meets the regulatory requirements for
casual exposure to the eye; however, looking directly into a laser can cause
eye damage.
WARNING: EN60825-1, Class 1 laser fiber connectors are for connection only
to Class 1 laser devices.
See "IOAs Requiring SFPs" on page 32 and the E120 and E320 Module Guide for information
on small form-factor pluggable transceivers (SFPs) used on IOAs.
After you have correctly cabled the SRP IOA, you must attach grounding and electrical
wires before you attempt system power-up. See Figure 27 on page 51.
Three main tasks are involved:
Switch all router power switches to OFF.
1.
CAUTION: Switches may have inadvertently flipped to ON during shipping
and installation.
Connect the grounding wires to the chassis.
2.
WARNING: Always connect the grounding wires first (before connecting
the power cables) and disconnect them last when installing or servicing
the router.
Connect the power cables to the PDUs.
3.
See "System Specifications" on page 89 for the power requirements for the router. Table
8 on page 51 identifies the cabling requirements.
