IBM System Storage N3700, Hardware And Service Manual

Page: 35 / 106

Note: N3700 storage systems with the current CPU module design ship with the
SFP module required for Port C. The early CPU module design uses an
integrated SFP for Fibre Channel Port C, so no external SFP module is
required for connections to Port C in early CPU module designs.
For more information about the differences between the early and current N3700
CPU module designs, see “Understanding the differences between early and
current N3700 CPU modules” on page 1.
v Use a fiber-optic cable that is:
– Appropriate to the Fibre Channel connection on your N3700 storage system
– Of an approved length for the third-party device
Note: See the documentation for the third-party device.
v Check the Interoperability Matrix at the following Web site to verify support for
your third-party device:
www.ibm.com/storage/support/nas/
An unsupported tape backup device might cause the N3700 storage system to
halt.

Connecting your N3700 storage system to an ASCII terminal console
The ASCII terminal console enables you to monitor the boot process, helps you
configure your N3700 storage system after it boots, and enables you to perform
system administration.
ASCII terminal console wiring
The following table lists the RJ-45 connection pinout of the N3700 console port on
the CPU module for use in connecting to your ASCII terminal console.
Table 3. RJ-45 connection pinout for the ASCII terminal wiring
Pin number Signal
1 Connected to pin 8
2 Not connected
3 TXD (from N3700 storage system)
4 GND
5 GND
6 RXD (to N3700 storage system)
7 Not connected
8 Connected to pin 1
DB-9 to RJ-45 console adapter pin connections
You use the included DB-9 to RJ-45 console adapter to connect an ASCII terminal
console to your N3700 storage system. Its purpose is to convert the RJ-45 pinout
on the N3700 storage system to a DB-9 pinout.
The following table lists the console adapter pin number connections between the
DB-9 male connector and the RJ-45 connector.
