Mounting the subracks into rack
.................................................................................................................................................................................................................................
Before you begin
This section describes the main use/configuration — the mounting of two
LambdaUnite
®
subracks into one rack. However, the procedure described below is in
principle also valid for mounting one subrack only (which should then be mounted in
the upper position). If a mixed configuration is used (
LambdaUnite
®
and
Metropolis
®
DMX subracks within one rack) please refer to
Appendix E, “Mixed configuration:
Procedure
Important!
It is very important to follow the instructions below exactly (step
by step). Otherwise there is a risk that the subrack will be put out of shape
and that it will not be possible to insert the XC circuit packs in the slots.
Proceed as follows to mount the subracks:
.................................................................................................................................................................................................
1
Unpack the subracks and check the installation materials.
.................................................................................................................................................................................................
2
Temporarily remove the front mounting brackets (DC1003774, item 1 and DC1003775,
item 2) from the subracks. The rear brackets should not be removed.
NOTE:
The items are related to
Figure 3-35, “Subrack mounting” (p. 3-63)
.................................................................................................................................................................................................
3
Mount 4 fiber clips (CC848850756, item 5) on the front mounting brackets of each
subrack.
.................................................................................................................................................................................................
4
Temporarily remove the rubber profile (DC1003971, item 6) from the lower subrack.
.................................................................................................................................................................................................
5
Slide each subrack from the rear into the rack.
If the subrack is located in the
...
then ...
upper position
use the subrack guides (CC848972220 (left) and
CC848972246 (right)) which are already mounted.
lower position
use the bottom of the rack frame as a guide.
