2.1.1.3.3 Inserting and Extracting AMC Modules
The OSN3 modules are designed for hot-swappable operation. Hot swapping allows the
coordinated insertion and extraction of modules without disrupting other operational elements
within the system. This allows for identified faulty elements to be removed and replaced without
taking the entire device out of service. In addition, the AMC module’s insertion-extraction handle
allows for quick-and-easy replacement of faulty modules.
The following procedure describes how to insert an AMC module into the chassis slot.
¾
To insert the module:
1.
Carefully insert the module into the slot until it makes contact with the AMC card-edge
connector located on the backplane.
2.
Connect all external interfacing cables to the module as required.
3.
Using the handle on the front panel, engage the module with the chassis backplane.
4.
When the handle is locked, the module is engaged; the HS LED turns off.
The following procedure describes how to extract an AMC module from the chassis.
Note:
Before extracting the HDMX module (if required), you must perform a hard-disk
drive dismount (i.e., a logical disconnection of the hard drive).
¾
To extract the module:
1.
Pull the handle on the module’s front panel and semi extract the module to the first “click”;
the module performs a shutdown sequence indicated by the flashing blue
Hot Swap
LED
(see stages 1 and 2 in the figure below).
2.
When the LED stops flashing and remains constantly on, disconnect any interfacing cables
that may be connected to the module.
3.
Using the module’s handle, pull the module out of the slot (see stage 3 in the figure below).
