Power Entry Modules
The Power Entry Module (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. Replacement can take place in under 30 minutes by a trained service
person.
The PEMs are accessible from the rear of the shelf and connect to the PEM connectors on the
backplane. A removable plastic housing covers the power feeds and returns to prevent
accidental shorting. The PEM also features an injector/ejector handle that provides the hot
swap mechanism for signalling the state of the PEM prior to removal.
The PEMs are hot-swappable and will not cause a fault when one is removed for replacement.
Two PEMs are required to support 2N+1 redundancy. If your system is configured for
redundant operation using two power feeds, they operate in load sharing where the total load
is equal to or less than what one power feed can provide.
1.1.8
Fan Tray Modules
The AXP 1410 supports two fan trays in a push/pull configuration. Each fan tray contains five
dual counter rotating fans. The lower fan tray is accessible from the front of the chassis and
contains the replaceable air filter. The upper fan tray is located in the rear of the chassis.

Fan Filter
The fan filter is installed in the lower fan tray.
