IBM Storwize V7000 - Viewing the event log

4. Pull the rail forward, away from the rear bracket, as shown in Figure 122 on page 109.
5. Repeat step “1” on page 109 through step “4” on page 110 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 the support rails: 2076-92F ” on page 26.
Connecting optional SAS expansion enclosures: 2076-92F
After you install 5U expansion enclosures into the rack, you must connect them to each system that will
use them. The system requires software version 7.8.0 or later. 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 2076-92F expansion enclosure.
Note: When you insert SAS cables, ensure that the connector is oriented correctly to the control
enclosure and expansion enclosure.
• For Storwize V7000 Gen2 systems, Storwize V7000 Gen2+ control enclosures, and 2U expansion
enclosures, the blue pull tab must be below the cable (
1 in Figure 123 on page 110).
Figure 123. SAS cable connector orientation
• For 2076-92F 5U expansion enclosures, the blue pull tab must be above the connector ( 2 in Figure
123 on page 110).
• 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.
• When inserted correctly, the connector can be removed only by pulling the tab.
Be aware of the following guidelines when you attach the cables to the SAS ports.
• No cable can be connected between a port on a left canister and a port on a right canister of the
expansion enclosures.
• Ensure that cables are installed in an orderly way to reduce the risk of cable damage when replaceable
units are removed or inserted.
• SAS cables must be routed through the cable management arms to reduce the risk of disconnecting the
nodes from their storage arrays. This step also helps to protect the SAS cables from getting damaged if
you slide the node or enclosure out of the rack while they are attached. Arrange your cables to provide
access to the following components:
– Ethernet ports, including the technician port. The technician port is used for initial setup of the
system by directly attaching to a personal computer. It can also be used to complete service actions
for the system.
– USB ports.
– Fibre Channel and Fibre Channel over Ethernet (FCoE) ports. If your system has an optionally
installed Fibre Channel and FCoE adapter for host and external storage attachment, ensure that
these ports are accessible.
