Control Station Input/output ports and connectors
The File/Unified VNX5400 platform 1U Control Station supports the following I/O ports on
the rear of the 1U Control Station:
◆ Five Ethernet (RJ-45) ports (one not used [labeled MGMT], see location 2 in Figure 20
on page 36)
◆ One serial console (DB-9 plug) connector
◆ One modem (DB-9 plug) connector
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to
telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports
contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution
when connecting cables.
Control Station Ethernet (RJ-45) ports
The File/Unified VNX5400 platform 1U Control Station comes with two integrated
dual-port Ethernet ports (labeled CS and A, respectively) and two Peripheral Component
Interconnect Express (PCI-E)
4
low profile card dual-port Ethernet ports (labeled B and
MGMT, respectively) in an expansion slot on the rear of the 1U Control Station.
Note: A fifth RJ-45 connector (labeled MGMT) is located to the left of the RJ-45 connected
labeled CS. This connector is not used at this time.
These ports (Figure 21 on page 38) provide an interface for connecting to 10-, 100-, or
1000-Mb/s networks and provide full-duplex (FDX) capability, which enables
simultaneous transmission and reception of data on the Ethernet local-area network
(LAN).
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 1U Control Station, as described in
Table 15.
4. PCI Express is used in consumer, server, and industrial applications, as a motherboard-level
interconnect (to link motherboard-mounted peripherals) and as an expansion card interface for
add-in boards.
