Cisco 6260 Chassis
1
If you are using 4xDMTs
2
If you are using 4xDMT over ISDNs
Cisco 6260.
3
If you are using 4xflexis in CAP mode, multiply 13.5W by the total number of 4xflexis (CAP
mode) in the Cisco 6260.
4
If you are using 4xflexis in G.lite mode, multiply 13W by the total number of 4xflexis (G.lite
mode) in the Cisco 6260.
5
If you are using 4xflexis in DMT mode, multiply 17.5W by the total number of 4xflexis (DMT
mode) in the Cisco 6260.
6
If you are using 4xSDSLs
7
If you are using 8xDMTs, multiply 24W by the total number of 8xDMTs in the Cisco 6260.
8
Enter 33.5W for each NI-2 card.
9
Enter 50 W for each PEM.
10
Enter 34.5W for each fan tray.
11
Add lines 1 through 10. This is the typical power required for the Cisco 6260.
12
Divide line 11 by 48. This is the nominal current for the Cisco 6260.
13
Multiply line 12 by 1.25. This is the minimum fuse rating needed to operate the Cisco 6260
in your system.
1. Complete this section for each subtending host.
2. 4xDMT = quad-port DMT ATU-C line card.
3. 4xDMT over ISDN = quad-port DMT over ISDN.
4. 4xSDSL = quad-port STU-C line card.
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.
Verify that the INPUT OK LED lights.
Step 2
If the INPUT OK LED does not light or if other issues arise, refer to the Cisco 6260 Hardware
