Quad-Port Flexi ATU-C to Octal-Port DMT ATU-C Line Card Conversion Procedures

Note The power rating label that is supplied on the rear of each chassis indicates the maximum fuse value

for the chassis.

Apply Power

Complete the following steps to apply power to the Cisco 6260 system:

Step 1 Set the circuit breakers on the PEMs to the ON (1) position.

The OUT FAIL LEDs might flash briefly.

Step 2 Verify that the INPUT OK LED lights.

Note If the INPUT OK LED does not light or if other issues arise, refer to the Cisco 6260 Hardware

Installation Guide for troubleshooting procedures.

Table 4 Fuse Calculation for the Cisco 6260 System Components

Component Instructions Calculation

Cisco 6260 Chassis

1. Complete this section for each subtending host.

If you are using 4xDMTs

, multiply 16.5W by the total number of line cards in the Cisco 6260.

2. 4xDMT = quad-port DMT ATU-C line card.

If you are using 4xDMT over ISDNs

, multiply16.5W by the total number of line cards in the

Cisco 6260.

3. 4xDMT over ISDN = quad-port DMT over ISDN.

If you are using 4xflexis in CAP mode, multiply 13.5W by the total number of 4xflexis (CAP

mode) in the Cisco 6260.

If you are using 4xflexis in G.lite mode, multiply 13W by the total number of 4xflexis (G.lite

mode) in the Cisco 6260.

If you are using 4xflexis in DMT mode, multiply 17.5W by the total number of 4xflexis (DMT

mode) in the Cisco 6260.

If you are using 4xSDSLs

, multiply 9W by the total number of 4xSDSLs in the Cisco 6260.

4. 4xSDSL = quad-port STU-C line card.

If you are using 8xDMTs, multiply 24W by the total number of 8xDMTs in the Cisco 6260.

Enter 33.5W for each NI-2 card.

Enter 50 W for each PEM.

Enter 34.5W for each fan tray.

Add lines 1 through 10. This is the typical power required for the Cisco 6260.

Divide line 11 by 48. This is the nominal current for the Cisco 6260.

Multiply line 12 by 1.25. This is the minimum fuse rating needed to operate the Cisco 6260

in your system.
