Unpacking the Hardware
When shipped, the HotWire 8800 DSLAM chassis is packed in a cardboard
shipping container. Carefully remove the chassis from its shipping container and
check for physical damage. If the chassis shows signs of shipping damage, report
this immediately to your shipping and sales representatives.
Pre-installation Considerations
Consider the following before performing the chassis installation:
Installation Site
Your installation site should be well-ventilated, clean, and free of
environmental extremes. There should be 2 to 3 feet of clearance at the front
of the rack in which the chassis is to be installed to allow access for the
installation of the chassis, circuit cards, and cables.
Power
The HotWire 8800 DSLAM operates from a standard CO – 48 Vdc power
supply (–40.0 to –60.0 Vdc). The power source wires must be between
10 AWG and 16 AWG, and can be either solid or stranded. However, the
preferred power source wire type is 14 AWG stranded.
Grounding
A copper lug connector is attached to the chassis grounding post. It can
accept a bare wire, 6 through 14 AWG.
Cabling
The following customer-provided cables and cable adapters are required with
this product:
— Telco 50-pin cable for connection to the CO POTS splitter shelf or MDF.
You will need one 50-pin cable for Slots 1 – 6, one 50-pin cable for
Slots 7 – 12, and one 50-pin cable for Slots 13 – 18.
— 6-pin modular cable for connection to a CO alarm system, if required.
— 8-pin UTP (Unshielded Twisted Pair) CAT5 modular cable for connection
to the DSL 10BaseT Ethernet ports. You will need a cable for each card
in the DSLAM.
— 8-pin UTP CAT5 modular cable for connection to management domain
LAN for SNMP management system or telnet access.
— A CAT5 serial cable and DB25 (male) adapter are shipped with the MCC
card. However, 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 9-pin serial port. For connection to a modem, you may
need to supply a null modem adapter.
