SBA Cable Routing for SEU Installed in Adjacent Cabinet to the Server
The SBA cable bundle must be routed using the path shown in Figure 4-31 when the SEU is installed in a
rack cabinet adjacent to the server.
Figure 4-17 SBA Cable Routing (Rear of Cabinets)
• When the Server Expansion Unit is installed in an adjacent rack to the server, adhere to the following
guidelines for installation:
— Two SEUs can be installed in a single rack cabinet.
— The racks must be either 41U or 33U. A 25U rack is not permitted for SEU installation.
— The rack cabinets must be installed with proper anti-tip feet, system interlock rods, and ballast.
— The two rack cabinets must be secured together with rack tie together kits and the rear doors of each
rack cabinet must be removed.
— The top of the SEU must be at the same level as the top of the host server to allow for a complete SBA
cable service loop. This is accomplished by routing the cable out the back of one rack cabinet into the
back of the other rack cabinet so both the host server and the SEU can be fully extended in the locked
position simultaneously.
— The space above and below the SEUs may be used, but care must be taken so equipment installed in
this space does not interfere with the interlock mechanism or SBA cable routing.
Ensure the top of the
server and the top of
the SEU are lined up
with respect to each
other.
