Warning:
• Do not remove a SF/CPM if a compact flash LED is lit green. If green, a read/write action is in
progress.
• 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 SF/CPM modules, configuration modifications are not required.
• All 7450 systems require at least one SF/CPM.
• Do not force an IOM into a SF/CPM slot.
• Do not force a SF/CPM into an IOM slot.
• When you remove a SF/CPM, always use the ejector levers to make sure that the connector
pins disconnect from the backplane.
• Removing the SF/CPM module causes the system to shut down. If you are not immediately
installing a replacement SF/CPM module, replace the empty slot with a blank panel and power
off the system until the SF/CPM module is replaced
7450 ESS-7 :
• Accommodates two SF/CPMs, one active and one standby. One SF/CPM is required for
operation.
• The SF/CPMs must be installed in center slots A or B.
