Prerequisites to Multiservice Switch 7420 installation
• See Unpacking a processor card (page 469) for FP and CP handling
instructions.
• Ensure that you have completed all site preparations.
• If you are installing Multiservice Switch equipment in a rack or cabinet,
ensure that it has been properly installed and grounded. For more
information, see Cabinet installation (page 61).
Multiservice Switch 7420 installation task flow
This task flow shows you the sequence of procedures you perform to install
Nortel Multiservice Switch 7420. To link to any procedure, go to Task flow
navigation (page 12).
CAUTION
Risk of electrostatic damage
When handling processor cards, wear a grounded antistatic wrist
strap so that you do not damage electronic parts. For more
information, see Avoiding damage from static electricity (page 135).

Multiservice Switch 7420 replacement
Replace a Nortel Multiservice Switch 7420 if a non-replaceable component
fails, for example, a fan failure or a failed power supply.
Prerequisites to Multiservice Switch 7420 replacement
• Before you can replace a shelf, you must assemble enough anti-static
packaging to protect the processor cards, and clear an area large enough
to temporarily store them. You also need to have appropriate packaging
materials so that you can store or ship the removed shelf. See Unpacking
a processor card (page 469) for FP and CP handling instructions.
• Some of the procedures in this task are not located in this document.
Ensure that you have access to the required documents.
Multiservice Switch 7420 replacement task flow
This task flow shows you the sequence of procedures to perform to replace a
Multiservice Switch 7420. To link to any procedure, go to Task flow navigation
(page 16).
CAUTION
Service loss due to outage
Replacing a device removes it from service for the duration of the
replacement. Minimize the impact of the outage by rerouting traffic to
other nodes in the network before powering down the device.
CAUTION
Risk of electrostatic damage
When handling processor cards, wear a grounded antistatic wrist
strap so that you do not damage electronic parts. For more
information, see Avoiding damage from static electricity (page 135).

Multiservice Switch 7440 installation
Install a Nortel Multiservice Switch 7440 on the floor or in a rack or cabinet.
Site preparation for free-standing Multiservice Switch equipment
Plan to run cables from the node to the nearest floor opening in a raised floor.
To accommodate the cables if you have a raised floor, you can cut an opening
into the floor at any point near the node. Do not cut under the footprint of the
unit. A 20.32 cm2(8 sq. in.) opening can accommodate the cables for a Nortel
Multiservice Switch 7420 or Multiservice Switch 7440.
Ensure that you will be installing the node on a sturdy, flat surface.
Prerequisites to Multiservice Switch 7440 installation
• See Unpacking a processor card (page 469) for FP and CP handling
instructions.
• Ensure that you have completed all site preparations.
• If you are installing the device in a rack or cabinet, ensure that it has been
properly installed and grounded. For more information, see Cabinet
installation (page 61).
• If you are installing a 32-port E1 TDM FP you will need to install a multiport
aggregate device. See Installing a multiport aggregate device (page 194).
• If you are installing a free-standing device with covers see Installing covers
for a Multiservice Switch 7440 (page 252).
CAUTION
Risk of electrostatic damage
When handling processor cards, wear a grounded antistatic wrist
strap so that you do not damage electronic parts. For more
information, see Avoiding damage from static electricity (page 135).
