The Fiber Remote Multi-IPE Interface unit activates a red alarm LED
when a fault occurs at the near-end and at the same time it activates the
yellow alarm LED on the corresponding Fiber Remote Multi-IPE Interface
unit at the far-end. It also provides an amber LED to indicate the test and
maintenance activity on the fiber-optic link. This amber LED will also light
if the system alarms are disabled.
Display codes
The Peripheral Controller card in the Remote IPE is equipped with
an alphanumeric display on the faceplate. The display is used to
automatically display the card status and identify possible faults with the
card by displaying specific codes that correspond to the card status.
These codes are displayed in hexadecimal notation and are listed and
interpreted in
diagrams" (page 149)
Administration (NN43001-611) () .
The display also performs the following functions:

•
The codes are also logged into a history file and can be printed and
reviewed to analyze the sequence of events leading to the presently
displayed status.
The last 16 codes displayed by the Peripheral Controller card are stored
in memory and can be reviewed and then cleared by using Network and
Signaling Diagnostic Program LD 30.
Enable/disable switch
The Superloop Network card is equipped with an ENL/DIS switch. This
ENL/DIS switch is located on the card's faceplate. It is used to disable
the card before removing it from an operating system without disrupting
other system functions. After repairing or replacing the card, put it back in
service by setting the switch to the ENL position.
System monitors and alarms
System monitoring units continuously monitor the environmental and
power status of the system and the individual system modules including
the Remote IPE equipment.
