5.5 Switch Board Replacement
The switch boards in the SFCS-1000 are hot-swappable, meaning that they
can be removed and replaced with the chassis under power. The proper pro-
cedure for hot-swapping a switch board is as follows:
WARNING!
It is highly recommended that you use the
included grounding strap when handling this,
or any other component.
CAUTION
Ensure that any unpopulated switch board
slots are covered with a blank panel before
turning on your SFCS-1000. Operating the
switch with any of these slots left open can
cause a significant temperature rise in a very
short time.
NOTE:
As a precaution, it is recommended that you
back up your CDB before performing this
process. Instructions for backing up your
CDB can be found in Appendix C, AMI
Operation Commands, of the Cabletron ATM
Switch Configuration Manual.
NOTE:
Only replace a switch board with another
switch board of the same type (i.e., an
SFCS-1000 switch board with an SFCS-1000
switch board).
