While the location of the RPSD Lock is not critical to its function, the Lock should
be kept in an equipment cabinet near the communications system modem. This
helps to protect the Lock against dust and other precipitate, as well as protecting
it against physical damage from being knocked to the floor or having things
dropped on it. You also can place it on a table near the communications system
modem. Avoid placing the Lock on top of the equipment cabinet because heat
tends to accumulate there.
NOTE:
NOTE:
A damaged Lock prohibits use of the port being protected. A secure
location for the RPSD Lock is very important to maintaining uninterrupted
service.
If more than one RPSD Lock is installed at a particular customer site, you may
stack the Locks on top of each other to save space. The Locks generate very
little heat, so you do not have to separate them.
NOTE:
NOTE:
In a multiple Lock installation, label the Locks according to which lines they
protect to prevent confusion.
Power Supply
The RPSD Lock and the RPSD Key are both powered by ordinary AC outlets or
by AC-to-12 VDC coverters connected to AC outlets. These need not be
grounded (three-prong) outlets. If necessary, you can use extension cords.
However, it is best to connect the Lock to the Uninterruptible Power Supply (UPS)
connected to the communications system. Otherwise, a power interruption can
result in a blockage of both incoming and outgoing calls on the port being
protected. If the modem to the RMATS channel is external (System 85 and
DEFINITY Generic 2 models), the modem also should be powered from the UPS.
NOTE:
NOTE:
A locked port is inaccessible during a power outage for the duration of the
outage. No administration of the RPSD Lock need be done when the
outage ends. When power is restored, the RPSD Lock device automatically
comes back on-line and resets itself to an Idle/Locked state. Key
information and parameters are unchanged by the outage.
The power pack for the Lock draws a maximum of 18 watts. This should not
place any great strain on the UPS but should be considered with the overall draw
on the UPS.
External surge protection is optional.
