Warning:
• Do not remove an 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 router 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 7750 routers 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 a SF/CPM module in a non-redundant system 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
7750 SR-12:
• Accommodates two SF/CPMs, one active and one standby.
