only to other SELV circuits. Because the DSL circuits are treated like telephone-network voltage,
avoid connecting the SELV circuit to the TNV circuits.
We recommend that you label each data cable at both ends to identify its destination.
Tip
Proper ESD protection is required each time you handle Cisco DSLAM equipment. Installation
Caution
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.
Installing the cards in the chassis with the power leads reversed can damage the cards.
Caution
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.
Do not reach into a vacant slot or chassis while you install or remove a line card or a fan. Exposed
Warning
circuitry could constitute an energy hazard.
All cards must be fully seated in the chassis. A push on the faceplate of each card is required for the card
Note
to be fully seated.
