Checking Physical Equipment
2-23
Introduction
This chapter discusses how to check physical connections and observe LEDs on
the BSR products. You should check power and network connections anytime you
install new hardware, or whenever a problem occurs.
The next sections describe how to check physical problems on the BSR:
• Checking BSR 1000 Power Connections
• Checking BSR 64000 Power Connections
• Checking Physical Network Connections
• Interpreting BSR 64000 LED Displays
Checking BSR 1000 Power Connections
Inspect any uninterruptible power supplies (UPS) connected to the BSR 1000.
Sometimes the UPSs can fail.
Checking BSR 64000 Power Connections
Inspect the power LEDs labeled A and B on the front of the Supervisory Routing
Module (SRM). If power source A or B failed, the corresponding LED displays a
failed condition. If the two -48V DC power filter modules A and B on the rear of
the unit are operational, check the -48V DC (40-60 V DC input) power source.
The power source could either be an AC-to-DC power converter, or a battery
connection attached to a charger. Make sure the power converter or charger is
operating properly.
