Rear Panel Description
This section provides a description of the rear panel of the 2X16SP-1000BT Gigabit SPAN
Matrix Switch.
An explanation of each rear panel legend follows:
3.2.1
Power
The AC
POWER
switch is a rocker style switch. The AC power switch circle icon depressed
is
OFF
. The AC power switch bar icon depressed is
ON
.
To power the unit ON:
Power
ON
the
2X16SP-1000BT by depressing the AC power switch bar icon. The powered
ON
2X16SP-
1000BT is indicated by the illuminated
green
POWER 1
and
POWER 2
LEDs on the front
panel.
3.2.2
Control
The
CONTROL
connector port is a shielded DB9 Female and is cabled to the
COM
port of any
compatible network tool or PC where HyperTerminal or Datacom Systems Switch Control
Software resides.
If this 2X16SP-1000BT Gigabit SPAN Matrix Switch is daisy-chained the
CONTROL
port will
be connected to the preceding switch
LINK
port.
3.2.3
Link
The
LINK
connector port is a shielded DB9 Male and is cabled to the
CONTROL
port of the
succeedomg 2X16SP-1000BT Gigabit SPAN Matrix Switch when daisy-chained.
3.2.4
Input Power
Two AC input power sockets are provided on the rear panel. The front panel
POWER 1
,
POWER 2
LEDs are illuminated
green
, respectively, when the AC power switch is depressed
ON
and AC power is available at both the two rear AC power sockets. Either
POWER 1
,
POWER 2
LED illuminated
red
indicates a defective power source and immediate
investigation as to the cause is required to insure redundant power integrity.
Although only one power supply is required to power the 2X16SP-1000BT, use of a second
independent power source is strongly recommended to assure uninterrupted monitoring.
Furthermore, connecting the second AC input power socket to a different external power
source circuit than the first AC input power source eliminates power as a single point of
failure.
