1. Prepare the Installation Site
Cabling Infrastructure
Ensure the cabling infrastructure meets the necessary network specifications.
See the following table for cable types and lengths, and see appendix B,
“Switch Ports and Network Cables” on
page B-1 for more information:
Table 2-1. Summary of Cable Types to Use with the Switch
Port Type Cable Type Length Limits
Twisted-Pair Cables
10/100/1000Base-T For either 10, 100 Mbps or 1000 Mbps
operation:
Category 5 or better, 100-ohm UTP or shielded
twisted-pair (STP) balanced cable. For 1000
Mbps (gigabit) operation, Category 5e cabling
or better is recommended.
100 meters
Note: The ProCurve 10/100/1000-T xl
Modules and 100/1000-T Transceiver are
compatible with the IEEE 802.3ab standard
including the
“Auto MDI/MDI-X” feature,
which allows use either straight-through or
crossover twisted-pair cables for
connecting to any network devices
including end nodes, such as computers, or
to other switches, hubs, and routers.
The Auto MDI/MDI-X feature only works
when the port is in auto-negotiation mode.
Fiber Optic Cables
Gigabit-SX
(on Gigabit-SX-LC
mini-GBIC) Multimode fiber-optic cables fitted with LC
connectors 220 meters to 550 meters depending on the
cable used. See “Fiber-Optic Cables” on
page B-3 for more information.
Gigabit-LX
(on Gigabit-LX-LC
mini-GBIC) Single-mode fiber-optic cables fitted with LC
connectors.
The multimode cables specified for the Gigabit-
SX mini-GBIC may also be used, but a mode-
conditioning patch cord may be needed — See
the
Installation Guide that came with your
module for more information.
• single-mode cable = 10 kilometers
• multimode cable = 550 meters
Gigabit-LH
(on Gigabit-LH-LC
mini-GBIC) The same single-mode fiber-optic cables as for
Gigabit-LX. • 70 kilometers
Note:
Gigabit-LH
- The transmission distances are dependent on the particular fiber loss and coupling loss involved, among
other factors, and can be estimated from the optical loss budget. For distances less than 20km, a 10dB attenuator must
be used. For distances between 20km and 40km, a 5dB attenuator must be used. Attenuators can be purchased from
most cable vendors.
