Warning:
• Electrostatic discharge (ESD) damage can occur if SF/CPMs, IOMs, or MDAs are mishandled.
Always wear an ESD-preventive wrist or ankle strap and always connect an ESD strap to the
grounding plug on the front of the chassis.
• Invisible laser radiation can be emitted from the aperture ports of an MDA when no cable is
connected. Avoid exposure and do not stare into open apertures.
• Always place components on an anti-static surface.
• Do not power up a 7750 SR-12 router until all components are installed and verified.
• Use only approved small form factor pluggable fiber optic devices in MDA ports. The MDA
installation guides list the types of SFP modules and connectors used with specific MDAs.
Notes:
General:
• Ports cannot be provisioned if the MDA is not preprovisioned.
• Services cannot be provisioned if ports are not provisioned.
• MDAs can be installed on an IOM two ways:
→
Install MDAs on the IOM and then load the unit into the chassis slot. See Installing an
MDA on an IOM on page 107 .
→
Install MDAs after the IOM is loaded in the chassis slot. See Installing an MDA on a
Chassis-Installed IOM on page 109 .
• For configuration purposes, MDA slots are numbered 1 (top slot) and 2 (bottom slot).
