Position And Port Numbering - 2N NetStar Hardware Manual

2.3 Position and Port Numbering

Each card and port is assigned a specific unique HW address.
The address consists of 4 parts and is stated in the form: R : C : B : P, whereas
the separate letters stand for the following:
R – rack
C – case
B – board
The basic module uses following rules for the card positions and assigning of
addresses.
Address 1
Addresses 2,3,4
Address 5
Addresses 6,7,8,9,10,11,12,13 and 14
P – port

Rack represents the entire system appliance consisting of the basic module
and four extension modules (case), in the current version only one Rack is
supported. The rack address is thus 0.
Covers the basic or one of the four extension modules.
The address of the basic module is 1, the extension modules are assigned
addresses from 2 to 5 according to their SWITCH card Connections.
The separate cards (board) are assigned addresses from left to the right,
both in the basic as well as the extension modules. The address of the first
position in the module is 1 and is reserved for maincase CPU or for
extender CPU.
Compared to the extension module, in which the cards are assigned
addresses from 1 to 12, the assigning of addresses in the basic module is
governed by predefined rules.
Reserved for controlling CPU only (position 1)
the card address is 0:1:1
Reserved for the PRI and VoIP cards (positions 2,3 and 4)
the cards addresses are 0:1:2, 0:1:3 and 0:1:4
Reserved for the SWITCH card (position 5)
the card address is 0:1:5
The addresses correspond to the positions 6,7,8,9,10,11,12,13 and 14 and
can be used for any line card. An exception are the positions with the
addresses 6, 9 and 12, in which if you use a BRI or DIGITAL COMBO card
the first 2 ports on the card are always NT and may not be changed.
The card ports are assigned the addresses from left to the right and from
top to the bottom.
The addresses start with 1.
For the purpose of better orientation the PRI, GSM and Audio/IO/Relay
cards have the serial numbers of the ports printed on their front side.
