Warning:
• Electrostatic discharge (ESD) damage can occur if IOMs, SF/CPMs, or MDAs are
mishandled. Always wear an ESD-preventive wrist or ankle strap connected to the grounding
plug on the front of the chassis. Always place chassis components on an anti-static surface.
• Blank panels and faceplates are required in all empty card and component slots to prevent
excess dust accumulation and to help control airflow and electromagnetic interference.
Notes:
General:
• When replacing an IOM, ports, MDAs, and card parameters must be shut down.
• All 7450 ESS-7 systems require at least one IOM.
• When you remove an IOM, always use the ejector levers to make sure that the connector pins
disconnect from the backplane.
• Removing an IOM module will not cause the system to shut down. If you are not immediately
installing a replacement IOM module, replace the empty slot with a blank panel.
7450 ESS-7:
• Accommodates a maximum of five IOMs.
