Danger:
• Only trained and qualified personnel should install or replace this equipment.
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.
Notes:
General:
• Ports cannot be provisioned if the MDA is not preprovisioned.
• Services cannot be provisioned if ports are not provisioned.
• MDAs can be attached to an IOM two ways:
→
Attach MDAs to the IOM and then load the unit into the chassis slot.
→
Install MDAs after the IOM is loaded in the chassis slot.
• For configuration purposes, MDA slots are number 1 (the left MDA slot) and 2 (the right MDA
slot).
