  • Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

Preventing Electrostatic Discharge Damage

Electrostatic discharge can damage equipment and electrical circuitry. Electrostatic discharge occurs when electronic printed circuit cards, such as those used in Installing the Cisco Multiprotocol Synchronus Serial NIM, are improperly handled and can result in complete or intermittent equipment failure. Always observe the following electrostatic discharge damage (ESD) prevention procedures when installing, removing, or replacing any electronic printed circuit cards:

• Make sure that the router chassis is electrically connected to earth ground.

• Wear an ESD-preventive wrist strap, and make sure that it makes good contact with your skin

  .

• Connect the wrist strap clip to an unpainted portion of the chassis frame to channel unwanted ESD voltages to ground.

Caution

The wrist strap and clip must be used correctly to ensure proper ESD protection. Periodically confirm that the resistance value of the ESD-preventive wrist strap is between 1 and 10 megohms (Mohm).

• If no wrist strap is available, ground yourself by touching the metal part of the router chassis.

Async Line Numbering

Asyncronous lines are not numbered in a linear format on the Cisco 4000 Series Integrated Service Routers platform. Due to the modular design of these routers, there are fixed line ranges for each slot and each slot is allocated 24 line numbers. This means that the span of line numbers does not change when you add or remove async lines from other slots. The following table shows the reserved line numbering per slot on Cisco 4000 Series Integrated Service Routers platforms.

For Cisco 4000 Series Integrated Service Routers platforms, line number for async interface starts from 2. Insert the line number only in slot 0/1 and after line number allocation slot 0 is used only in special cases.

96 (24*4) line number is reserved for each slot, and 24 line number for each subslot.

For slot 1 and 2, line number allocation is:

Slot	Subslot	Reserved Line Numbering
0	1	2-25
0	2	26-49
0	3	50-73
1	0	98-121
2	0	194-217
