Clustered power connections
router, switch, or other suitable device. Optical fibre connectivity that does not
go over a public network does not require an additional connectivity device.
2. Use Figure 19 on page 47 to verify that the recommended disk components are
cabled correctly. (Connections to the customer's host network not shown in this
figure).
3. Make any necessary adjustments to cable labeling or placement, then go to
"Powering-up the components" on page 69.
This section provides steps for cabling the components included in the purchase of
the TS7650G clustered gateway to each other, as well as to the power distribution
units (PDUs), to the recommended disk controllers, and to the customer network.
If any other components are being used, review this information for general
guidelines, then refer to the manufacturers' documentation for cabling details.
Tip: For simplicity and ease of use, the instructions for each type of cable
connection (power, Ethernet, and fibre channel) start on a new page. Within the
Ethernet and fibre channel sections there are separate VTL and OpenStorage
subsections.
Notes:
v Cat 5e or higher cable is required for all Ethernet connections.
v Route all cables through the cable management arms and secure with straps.
v When attaching power cords, do so in a way that they will not interfere with
future FRU replacement.
v In clustered configurations, the server in the lower position in the frame is
Server A (or Node A), and the server in the upper position in the frame is server
is Server B (or Node B).
v In the following diagrams, the letters TJ followed by a number (for example:
TJ5) indicate which outlet the associated component plugs into on the top PDU.
The letters BJ followed by a number (for example: BJ8) indicate which outlet the
associated component plugs into on the bottom PDU.
v When connecting power for the WTI network power switch, use the
product-specific cables designed for the switch. Other types of power cables will
not work.
v If non-recommended components are being used, review this chapter for general
guidelines, then refer to the manufacturer's documentation for details.
v When applying cable labels, align the center reference lines on the label with the
axis of the cable. Refer to the IBM System Storage TS7600 with ProtecTIER Labeling
Instructions for the TS7650/TS7650G (3958 DD4 and 3958 AP1), IBM part number
46X6059, located on the IBM System Storage TS7650 with ProtecTIER Publications
CD provided in the MES ship group, for detailed label placement guidelines and
instructions.
This task describes cabling the power connections for a clustered TS7650G.
