and check for physical damage. If the 8600 chassis shows signs of shipping
damage, report this immediately to your shipping and sales representatives.
Pre-installation Considerations
Consider the following before performing installation of the 8600 chassis:
H
Installation Site
Your installation site should be well-ventilated, clean, and free of
environmental extremes. If you are installing the HotWire 8600 DSLAM
chassis in a Central Office rack, make sure there is 2 to 3 feet of clearance at
the front of the rack in which the 8600 chassis is to be installed to allow
access for the installation of the chassis, circuit cards, and cables.
H Power
The ac power version requires a power source of 100 – 250 Vac
@ 50 – 60 Hz; maximum current draw is 3 amps @ 110 Vac.
The dc power version requires a – 48 Vdc power source (–40.0 to –60.0 Vdc;
maximum current draw is 2 amps). The size of power source wires must be
between 14 AWG and 18 AWG, and can be either solid or stranded.
However, 16 AWG stranded wire is recommended.
H Grounding
A ground lug is located at the center of the cover at the rear. It accepts
14 AWG wire.
A non-insulated banana jack is located at the left front side of the unit to
provide a ground for the ESD wrist strap plug.
H Stacking
Up to three 8600 chassis may be physically stacked safely on top of each
other. However, for stacks of more than three, start a second stack or mount
in a 19- or 23-inch rack. Contact your sales representative for ordering
information.
H Cabling
The following customer-provided cables and cable adapters are required with
this product:
— Plug-ended Telco 50-pin cable for connection from the HotWire 8600
DSLAM Line ports to the CO POTS splitter shelf or MDF.
— 8-pin UTP (Unshielded Twisted Pair) CAT5 modular cable for connection
from each DSL card in the HotWire 8600 DSLAM to the LAN or WAN.
You will need one 8-pin modular cable for accessing the LAN/WAN
circuits of each DSL.
— 8-pin UTP CAT5 modular cable for connection from the HotWire 8600
DSLAM MANAGEMENT MCC port to a 10BaseT hub connector
(connected to an SNMP management system network).
— 14-foot CAT5 serial cable and DB25 adapter are shipped with the MCC
card. For connection to a terminal or computer, you may have to supply a
(female) DB9 to (male) DB25 adapter if your terminal or computer has a
