4. Pull the rail forward, away from the rear bracket, as shown in Figure 130.
5. Repeat step 1 on page 135 through step 4 for the other side of the rail assembly.
Replace the support rails
6. To reinstall the support rails, or replace them with support rails from FRU
stock, follow the procedure in “Installing or replacing the support rails:
2145-92F” on page 58.
Connecting the optional 2145-92F SAS expansion enclosures
After you install SAS expansion enclosures into the rack, you must connect them
to each 2145-SV1 or 2145-DH8 node in the I/O group that will use them.
Before you begin
Important: To support the 2145-92F expansion enclosure, 2145-SV1 and 2145-DH8
systems require software version 7.8.0. Do not connect the expansion enclosure if
software version 7.8.0 is not installed on the system.
About this task
This task applies if you are installing a 2145-92F expansion enclosure. When you
insert the SAS cables, ensure that the connector is oriented correctly to the node
and expansion enclosure.
v For 2145-24F or 2145-12F expansion enclosures, the blue pull tab must be below
the cable (
▌1▐
in Figure 131).
v For 2145-SV1 or 2145-DH8 nodes and 2145-92F enclosures, the blue pull tab
must be above the connector (
▌2▐
in Figure 131).
v Insert the connector gently until it clicks into place. If you feel resistance, the
connector is probably oriented the wrong way. Do not force it.
v When inserted correctly, the connector can be removed only by pulling the tab.
