Network management and service laptop Ethernet (RJ-45) ports
The SP Ethernet (RJ-45) ports are LAN ports not WAN ports. LAN ports contain safety
extra-low voltage (SELV) circuits, and WAN ports contain telephone-network voltage (TNV)
circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when
connecting cables. To avoid electric shock, do not connect TNV circuits to SELV circuits.
The Block and File (Unified) VNX5300 platform SP comes with two integrated dual-port
Ethernet ports (labeled with a network management symbol and a wrench symbol,
respectively). These ports provide an interface for connecting to the public LAN and a
service laptop computer, respectively. The ports are 8-pin MDI RJ-45 type ports for either
IEEE 802.3 10BASE-T (10 Mb/s), IEEE 802.3u 100BASE-TX (100 Mb/s), or 1000BASE-T
(1000 Mb/s) Ethernet connections.
Figure 23 shows an example of the SP network management and service laptop Ethernet
(RJ-45) ports.

IMPORTANT
The ports shown in Figure 23
a line through it indicates that you should not connect WAN type RJ-45 telephone
connectors to these ports.
To access the Ethernet ports, connect a Category 3, 4, 5, 5E, or 6 unshielded twisted-pair
(UTP) cable to the RJ-45 connectors on the back of the SP, as described in
Table 16 Ethernet cabling guidelines
