Ordering a replacement control blade
Procedure
Step 1
Take the required antistatic precautions to avoid static electricity damages. This includes reading
the Safety Guide for the SCOPIA Elite 5200 Series MCU and among other precautions wearing a
wrist strap.
Step 2
Unscrew the retention screws of the control blade (see
). Use a Phillips
screwdriver if required.
Step 3
Rotate the latch and slide the control blade out of its slot (see
).
Step 4
Slide the replacement control blade into the chassis slot until the outer panel of the control blade
is aligned with the chassis panel. Rotate the latch inward to secure the blade connections inside
the chassis.
Step 5
Tighten the blade retention screws.
Step 6
Check that the fans function and that the MCU interface screen does not display any alarm.
Replacing the MCU Fan Drawer
The fan drawers are located on each side of the MCU chassis. The fan drawers must be installed
when the system is operational. The right-side fan draws the cooling air inside the chassis through
a filter. The cooling air circulates inside the card cage and the left-side fan blows the air outside
the chassis.
The filter that is attached to the right fan drawer can be cleaned or replaced as explained in
“Cleaning or Replacing the MCU Air Filter” on page 8
Warning
You can replace the fan drawers without powering off the MCU only if you are able to do so
within five minutes. Otherwise, we recommend that you power off the MCU before
replacing a fan drawer.
