Equipping rules
Each 2x100BT-P2P 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 2x100BT-P2P circuit packs in slots 3
through 10. 2x100BT-P2P circuit packs only operate in an unprotected mode.
Users can install only 2x100BT-P2P, 4x100BT, 4x100FX, and
2xGigE/FC-P2P circuit packs in adjacent slots. Only ports 1 and 2 of the I/O
module will be used by the 2x100BT-P2P circuit pack. The remaining ports
remain unused.
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 2x100BT-P2P 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 2x100BT-P2P circuit
packs in slots 5 or 6 (there is not enough room for slot 5 or slot 6’s 8xRJ-45
I/O modules).
