Removing a sparing panel
Remove a sparing panel if you are decommissioning the services that require
it or if you are replacing or upgrading the sparing panel.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
Procedure steps
1 Obtain the site record of the sparing panel connections. Label each cable
and record the connection of each relative to the panel. (Labelling cables
should already have been done during initial installation.)
2 On the sparing panel, unplug all of the cable connections starting with the
control cables. Put the cables aside temporarily so that they are not
snagged by the removal of the panel.
Disconnecting the second FP control port cable cuts off the power source
for the sparing panel. Loss of power is indicated by no LEDs being lit.
3 If the sparing panel is rack-mounted, remove the grounding cable where
it is attached to the panel. Put the screw aside for re-use.
WARNING
Risk of injury or equipment damage by impact
A sparing panel can be heavy and awkward for one person
to install. Have a helper available at the start of the
installation. Do not drop or bump the panel into anything,
as injury or damage can occur.
