Verifying Package Contents
Note Carefully remove the contents from the shipping container, and check each item
for damage. If any item is missing or damaged, contact your Cisco representative
or reseller for support. Return all packing materials to the shipping container and
save them.
The switch is shipped with these items:
• Catalyst 2955 Hardware Installation Guide (Cisco part number
DOC-7814944=)
• Power and relay connector
• Switch installation protective liner
• One ferrite
• One RJ-45-to-DB-9 console port adapter cable
Note To connect the switch functional ground, you need a ring terminal lug (such as
Thomas & Bett part number RC10-14 or equivalent).
If you want to connect a terminal to the switch console port, you need to provide
an RJ-45-to-DB-25 female DTE adapter. You can order a kit (part number
ACS-DSBUASYN=) with that adapter from Cisco.
