Management (RJ-12) port connector (not used)
Note: The management Ethernet (RJ-12) LCC to SPS port connector is not used in the
VNXe3100 platform.
shows the management port (labeled with two symbols; one depicting a
telephone handset with a line through it and the other depicting a battery). The telephone
handset with a line through it symbol means that you cannot connect telephone type
circuits to this connector (see the following WARNING). This port connects the LCC (A and
B) ports to the SPS (A and B) ports, respectively.
The SPS (RJ-12) port is a LAN port not a WAN port. LAN ports contain safety extra-low
voltage (SELV) circuits, and WAN ports contain telephone-network voltage (TNV) circuits.
An RJ-45 (or TNV-type) looks the same as the RJ-12 except for two very important
differences. An RJ-45 is an 8-wire modular jack. The RJ-12 is a six-wire modular jack. The
RJ-45 plugs and jacks are wider than their RJ-12 counterparts - 7/16" vs 3/8". An RJ-45
plug won't fit into an R-J12 jack. But an RJ-12 plug will fit into an RJ-45 jack. Use caution
when connecting cables. To avoid electric shock, do not attempt to connect TNV circuits
to SELV circuits.
Figure 35 LCC RJ-12 port
The cable connecting the LCC to the SPS is an RJ-12 to RJ-12. It has an RJ-12 adapter (LCC
side) on one end and a RJ-12 (SPS side) adapter on the other end.
