6. Unlock ejector handle by pressing the handle and pull down.
The SAM should start to move out of the chassis. Do not force it. If the SAM
does not move, check the captive screw to make sure it is fully unscrewed.
Unscrew until loose and rotate the ejector handle down.
7. Remove the module from the shelf.
6.3 Unused Slots
All unused node or hub slots must be covered with filler blades. These filler blades ensure a
consistent airflow per slot whether or not the neighboring slot contains an AdvancedTCA
blade. There are filler blades sized for the front and for the RTM slots. An unused slot cannot
contain a front filler when an AdvancedTCA RTM is installed. When fillers are used, both the
front and RTM filler must be in place. Filler blades are available from Artesyn.
6.4 Installing Power Entry Modules
The AXP1440 shelf supports two Power Entry Modules (PEMs). Since the shelf is equipped with
a redundant power distribution system, the removal of a single PEM does not interrupt system
operation. PEMs are accessible from the rear of the shelf. Each PEM has EMI gaskets on all sides
of the module that provide EMI shielding.
The following instructions describe how to replace a power entry module. For further
information on power entry modules, refer to
Power Entry Modules (PEMs) on page 61 .

Read all cautions and warnings, and make sure the equipment is properly grounded by
reviewing the procedure in
Grounding the Shelf on page 93
. The PEM has multiple power
sources. This procedure should be followed precisely to ensure the PEM is isolated from
all power sources before removing the PEM from the shelf, or removing the plastic
terminal block lug cover.
This procedure assumes that the redundant PEMs are powered on in the shelf.
