OPTera Packet Edge System 4x100BT circuit pack
(NTN433BB)
Each OPTera Packet Edge System circuit pack works as a distributed switch
and bridge to connect Ethernet LANs on a high-speed SONET network.
Equipping rules
Each OPTera Packet Edge System 4x100BT circuit pack requires an
8xRJ-45 Front I/O module (NTN452NA) on the OPTera Metro 3500 Shelf
(NTN476AA, NTN476DA). On the OPTera Metro 3500 Universal Shelf
(NTN476AH) you must use the 8xRJ-45 Front Enhanced I/O module
(NTN452NH) or the 8xRJ-45 Rear I/O module (NTN452HB).
Both versions of the shelf support eight OPTera Packet Edge System 4x100BT
circuit packs in slots 3 through 10. 4x100BT circuit packs only operate in an
unprotected mode.
If a 2x100BT-P2P, 4x100FX, 4x100BT or 2xGigE/FC-P2P circuit pack is
inserted into an odd slot (n
odd
), then you can only insert one of the following
circuit packs into the even slot (n
odd
+1):
• 2x100BT-P2P
• 4x100BT
• 4x100FX
• 2xGigE/FC-P2P
If a 2x100BT-P2P, 4x100FX, 4x100BT or 2xGigE/FC-P2P circuit pack is
inserted into an even slot (n
even
), then you can only insert one of the following
circuit packs into the odd slot (n
even
-1):
• 2x100BT-P2P
• 4x100BT
• 4x100FX
• 2xGigE/FC-P2P
Note: There is no equipment protection for the 4x100BT circuit pack.
See Table 3-3 on page 3-6 for operational temperature ranges.
Note 1: If there is a 1-28 DS1 I/O module installed, and if slots 5 and 6 are
not equipped with DS1 mappers, you may not install 4x100BT circuit
packs in slots 5 or 6 (there is not enough room for slot 5 or slot 6’s 8xRJ-45
I/O modules).
Note 2: If there is a 29-56 DS1 I/O module installed, and if slots 7 and 8
are not equipped with DS1 mappers, you may not install 4x100BT circuit
packs in slots 7 and 8 (there is not enough room for slot 7 or slot 8’s
8xRJ-45 I/O modules).
