SPE Optional Boards
Packet Intfl?
These fields indicate if a Disk circuit pack is present, and identify
administered Packet Interface slots. If a Packet Interface circuit pack is
present, the corresponding Packet Interface field is set to y when the
system boots. No change to that field is allowed. If the system is
equipped with duplicated SPEs, the Packet Interface field is set to
y if either SPE carrier contains a Packet Interface circuit pack in the
corresponding position. If a Packet Interface circuit pack is not present,
the value for the
Packet Interface field is read from translation
data, and stored on disk or tape. If the field is set to n, a Packet Interface
circuit pack may be administered by changing the corresponding
Packet Interface field to y.
This field identifies the presence of
Packet Interface 1 (always
set to y for csi and si models).
Packet Intf2?
This field identifies the presence of Packet Interface 2 (always
set to y for the si model). It is changeable for the csi model. If set to y for
the csi model, the Bus Bridge and Inter-Board Link
Timeslots
fields display. Default is n.
Packet Intf3?
This field identifies the presence of Packet Interface 3
(Unavailable in the si and csi models). It is changeable in the r model.
Default is n.
Bus Bridge
(If Packet Intf2 set to y) This field gives the location of the C-LAN
circuit pack performing the bus bridge functionality when the packet bus
is activated. Enter the 5-character circuit pack number (CCcss, where CC
= cabinet number 1-3, c = carrier A-E, ss = slot number 0-20). Default is
blank.
Inter-Board Link
Timeslot Pt0
The number of timeslots to be used for port 0 on the Inter-Board Link.
Displays only if the switch model type is csi and the
Packet Intf2
field is y. Enter the number of timeslots (1-9) to be used by this
Inter-Board Link port. Default is 6.
Inter-Board Link
Timeslot Pt1
The number of timeslots to be used for port 1 on the Inter-Board Link.
Displays only if switch model type is csi and the
Packet Intf2 field is
y. Enter the number of timeslots (1-3) to be used by this Inter-Board Link
port. Default is 1.
Inter-Board Link
Timeslot Pt2
The number of timeslots to be used for port 2 on the Inter-Board Link.
Displays only if switch model type is csi and the
Packet Intf2 field is
y. Enter the number of timeslots (1-3) to be used by this Inter-Board Link
port. Default is 1.
