3.5.1 Serial DB9
The SERIAL connector port is a shielded DB9 Female and is cabled to the COM port of any
compatible network tool or PC where terminal emulation software resides. The cable is a parallel
straight-through cable (EIA232 Standard, DRL512-2M-R serial cable, DB9 M/F straight thru) with
no cross-overs or self-connects in the connector hoods. The SERIAL connector port is the only port
that can easily connect the Management PC to set the IP address (default 192.168.1.1) for the first
time. This drawing shows the DB9 Female Pin Assignment:
3.5.2 Power Switch (SFP series)
The front panel POWER 1, POWER 2 LEDs are illuminated green, respectively, when the DC power
switch is depressed ON and DC power is available at both the two rear DC 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.
3.5.3 Rear Label (BT series)
Identifiers for DB9, Serial Number (SN), Media Access Control (MAC) address, certification
compliance, input power requirements and various other information is provided.
3.5.4 Rear Labeling (SFP series)
Identifiers for Serial Number (SN), Media Access Control (MAC) address, certification
compliance, input power requirements and various other information is provided.
3.5.5 Input Power
Two DC input power sockets are provided on the rear panel. The front panel POWER 1 and 2
LEDs are illuminated green, respectively:
(SFP series) - when the DC POWER switch is depressed ON and DC power is available at
both the two rear DC power sockets; or
(BT series) - when DC power is available at both the two rear DC power sockets.
Either POWER 1 or 2 LED not illuminated when powered, indicates a defective power source and
immediate investigation as to the cause is required to insure redundant power integrity.
Although only one switching AC adapter power supply is required to power the configurable unit,
use of a second independent power source is strongly recommended to assure uninterrupted
monitoring. Furthermore, connecting the second DC input power socket to a different external
power source circuit than the first DC input power source eliminates power as a single point of
failure.
