Field Replaceable Units
7450 ESS-7
Page 119
Notes:
• The 7450 ESS-7 requires a minimum of one DC PEM
or
one AC PSM and one AC PEM to
operate. Additional modules are recommended for redundancy.
• For full redundancy, each PEM should be attached to an independent power source with a
dedicated circuit breaker.
• In the event of a power module failure, the entire power module must be replaced. There are
no field serviceable parts inside the PSMs or PEMs.
