Tools and Equipment Required
You might need to order the following equipment:
•
One-to-one 22-pin to 8-pin cable—Needed for Cisco 2500 series routers and
Cisco MC3810 multiservice concentrators
•
Y-cable—Needed for fully redundant power configurations
•
Upgrade kit—Needed for routers that originally came with AC or DC power
supplies (Cisco 2500 and Cisco 2600 series routers; Cisco 3620, Cisco 3640,
and Cisco 3725 routers; Cisco 4000 series routers; and the Cisco MC3810
multiservice concentrator)
Cabling Options
The external devices have different configuration and cabling options outlined
below and are discussed in detail under the referenced section of this manual:
•
The Cisco 1516M hub (HP 10BASE-T Hub-16M) only supports a one-to-one
cable for quasi-redundant configuration. This hub does not support
connection of its AC power cable for redundancy with reboot or the use of the
Y-cable for full redundancy.
•
FastHub 400 series 100BASE-T hubs support:
–
One-to-one cable for quasi-redundancy
–
One-to-one cable with the switch AC power cable connected for
redundancy with reboot (not recommended)
Refer to the
“Connecting Hubs” section on page 4-2
for illustrations and
procedures.
•
Catalyst 1900 series switches, Catalyst 2820 switches, Catalyst 2900 series
XL switches, and Catalyst 3500 series XL switches support:
–
One-to-one cable for quasi-redundancy
–
One-to-one cable with the switch AC power cable connected for
redundancy with reboot (not recommended)
See the
“Connecting Switches” section on page 4-6
for illustrations and
procedures.
