Accept Hardware Configuration needs to be applied. This will accept the new
hardware configuration and clear the alarm.
7.11.4 Removing a Module
Caution!
To avoid damaging the module, always handle carefully ( see Section 7.11.1 ) and
avoid electrostatic discharge ( see Section 7.11.2 ).
To remove a module:
1. Loosen the two captive screws that retain the module in the base unit.
2. Holding the captive screws, pull the module from the unit and place it in suitable
anti-static packaging.
3. Fit a blanking panel in place of the removed module.
4. When the unit detects a card is no longer present, it will be displayed on the
Option Slots web page, and an alarm will be raised. If all options are reported
correctly, the Accept Option Slot Configuration needs to be applied. This will
accept the new hardware configuration and clear the alarm.
7.11.5 Replacing (Hot-Swapping) a Module
A module can be replaced on a like-for-like basis without powering down the base
unit, i.e. can be ‘hot-swapped’. This will cause services to be allocated to other
modules, if available, enabling the removal of the module in question. In this way,
essential maintenance can be carried out with minimum disruption.
The replacement module must be of the same type and at the same software
version as the original. The replacement module must be fitted into the same option
slot as the module it is replacing.
To perform a hot-swap, the modules should only be unplugged or inserted when the
unit is fully booted and configured.
Only ONE module should be ‘hot-swapped’ at a time, to prevent problems due to
inrush current, and to ensure that the host recognizes and configures the new
module. A wait time of at least 40 seconds is recommended between removing the
module and replacing or inserting a new module.
Note: It could take between 2 and 4 minutes from inserting the module for it to be
recognized, configured and producing video output, following a hot-swap
operation.
