1.2.2 I/O Connectors and Status LED Indicators
Figure 1-4 shows the position of the I/O connectors at the back of the S2A9550 4FC unit.
The four
HOST
ports (SFP connectors) are used for Fibre Channel host connections.
You may connect your host systems directly to these ports or connect the ports to your
Fibre Channel switches and hubs. When an FC signal is present on the port (4G), the
respective LED turns solid green. Blinking green LEDs indicate activity A solid amber
LEN indicates failure(1G or 2G). A blinking amber LED indicates activity (1G or 2G).
There is no solid RED LED status. A slow blink RED LED indicates no connection.
The
DISK
ports (SFP connectors) are for disk connections. The ten ports are labeled by
data channels (ABCDEFGHPS). They are also color-coded to facilitate easy installation.
When an FC signal is present on the port, the respective LED turns green. Blinking LEDs
indicate activity.
The
CLI
connector provides local system monitoring and configuration capabilities and
uses a standard DB-9 Null Modem female-to-male cable.
The
TELNET
connector provides remote monitoring and configuration capabilities. The
ACT
(Activity) LED flashes green when there is Telnet activity. The
LINK
LED is off
when there is no Ethernet link. The
SPEED
LED turns
amber
when the link speed is
100 MB/s
, turns
green
when the link speed is
1000 MB/s
, and is
off
when the link speed
is
10 MB/s.
The
S2A LINK
port is used to connect single S2A9550 units to form a couplet via a
cross-over Ethernet cable. The
ACT
(Activity) LED flashes green when there is Telnet
activity. The
LINK
LED is off when there is no Ethernet link. The
SPEED
LED turns
amber when the link speed is 100 MB/s , turns green when the link speed is 1000 MB/s ,
and is off when the link speed is 10 MB/s.
The
S2A COM
port is a RS-232 Interface that uses an RJ-45 cable.
The
A/B
switch allows the user to configure the units as Unit A or Unit B. Each unit has
an activity LED. It is green for the selected unit
Figure 1-5 shows the LEDs at the back of the S2A9550 4FC unit.
The
SYSTEM STATUS
LED is green when the entire storage system is operating
normally.
