Cisco 6130 NI-1 to NI-2 Conversion Procedures
Caution
If the power connections are improperly connected and power is applied while the cards
are installed, the cards and chassis could be damaged.
Step 3
Verify that the power connections from the Cisco 6130 to the fuse and alarm panel are wired as shown
in Figure 6 or Figure 7.
Step 4
Check the polarity of the –48 VDC connections to each chassis by attaching a voltmeter with the minus
lead on –48 RTN and the plus lead on –48 V_A. Ensure that the meter reads between –36 VDC and
–60 VDC. If your voltmeter shows a positive voltage, the power inputs might be reversed. If the
voltmeter shows a negative voltage that is out of the –36 VDC to –60 VDC range, check the power
supply for failure or check for a blown fuse in the fuse and alarm panel.
Verify Fan Tray Operation
Verify that the fans are operational by locating the LED on the front of each fan. If the LED is
•
Green—The fan is operational.
•
Not green—The fan is not operational and the fan tray is in alarm mode. Refer to the Cisco 6130
with NI-2 Hardware Installation Guide for corrective action.
Caution
It is important that the Cisco 6130 cooling fans run continuously.
Warning
The power supply circuitry for the Cisco DSLAM equipment can constitute an energy
hazard. Before you install or replace the equipment, remove all jewelry (including rings,
necklaces, and watches). Metal objects can come into contact with exposed power
supply wiring or circuitry inside the DSLAM equipment. This could cause the metal
objects to heat up and cause serious burns or weld the metal object to the equipment.
Warning
Do not reach into a vacant slot or chassis while you install or remove a line card or a
fan. Exposed circuitry could constitute an energy hazard.
Install the NI-2 Card
Caution
Proper ESD protection is required each time you handle Cisco DSLAM equipment.
Installation and maintenance personnel should be properly grounded using ground straps
to eliminate the risk of ESD damage to the equipment. Cards are subject to ESD damage
each time they are removed from the chassis.
