Chapter 6 Upgrading and Maintaining the Cisco 6260 System
Installing and Replacing Hardware
Warning The ports labeled "ENET," "CNSL," and "AUX" are SELV circuits. SELV circuits should be connected
only to other SELV circuits. Because the DSL circuits are treated like telephone-network voltage,
avoid connecting the SELV circuit to the TNV circuits.
Tip We recommend that you label each data cable at both ends to identify its destination.
Caution Proper ESD protection is required each time you handle Cisco DSLAM equipment. Installation
and maintenance personnel should be properly grounded by means of 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.
Caution Installing the cards in the chassis with the power leads reversed can damage the cards.
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.
Note All cards must be fully seated in the chassis. A push on the faceplate of each card is required for the card
to be fully seated.
6.3.3.1 Installing a DS3+T1/E1 IMA NI-2 Card
Complete the following steps to install a DS3+T1/E1 IMA NI-2 card in the chassis. It is important that
you complete each step before moving on to the next step.
Note All cards must be fully seated in the chassis. A push on the faceplate of each card is required for the card
to be fully seated.
Step 1 Connect a grounding strap to the ESD grounding jack that is located on the top right of the Cisco 6260
card cage.
Step 2 Inspect the NI-2 card. Verify that the daughterboard is fully seated on the main board.
Step 3 Verify that the NI-2 card slot in the chassis has no bent pins.
Step 4 Hold the NI-2 card with the faceplate toward you and the connectors facing the chassis slot.
