The FTM is hot swappable and may be managed through the IPM Sentry software for hot swap.
If your system is not running high-availability software, behavior of the LED may be
indeterminate. The face plate of the FTM has the following indicators:
2.9 Power Entry Modules (PEMs)
The PEM is a Field Replaceable Unit (FRU) and can be replaced while the system is on, but the
power for the PEM being replaced (PEM A or PEM B) must be shut down at the external source
prior to replacement. Replacement can take place in under 30 minutes by a trained service
person.
For important information on removing power before replacing a PEM, refer to Powering Down
the System on page 79 and DC Power Entry Module (PEM) on page 80 .
The PEMs are accessible from the front of the shelf. Power supplied to the PEM enters the
chassis from the rear on the DC inlet 2-hole lugs. A removable plastic housing covers the power
feeds and returns to prevent accidental shorting on the DC inlet. Once power is removed at the
external source, the PEM may be removed and replaced from the front of the shelf.
