Installing the optional 2U SAS expansion enclosure into the rack
The 2145-12F or 2145-24F SAS expansion enclosures can be installed in a separate
rack or in the same rack as the SAN Volume Controller nodes.
About this task
Note: Up to 20 optional SAS expansion enclosures can be connected to each pair
of SAN Volume Controller nodes (I/O group).
CAUTION:
v To lift and install the SAS expansion enclosure into the rack requires at least
two people.
v Install a SAS expansion enclosure only onto the rails that are supplied with
the enclosure.
v Load the rack from the bottom up to ensure rack stability. Empty the rack
from the top down.
Procedure
To install an optional SAS expansion enclosure, complete the following steps.
1. On either side of the drive assemblies, remove the enclosure end caps by
grasping the handle and pulling the bottom of the end cap free, then clearing
the tab on the top of the enclosure. (See Figure 37.)
2. Align the enclosure with the front of the rack cabinet.
3. Carefully slide the enclosure into the rack along the rails until the enclosure is
fully inserted (see Figure 38 on page 34).
Note: The rails are not designed to hold an enclosure that is partially inserted.
The enclosure must always be in a fully inserted position.
