Multiaccess Enclosure Slots and Adapters
There are two large slots, designated
A and B, on the multiaccess enclosure Slot A
is unused. Slot
B is occupied by the system card. In addition, there are eight
adapter slots, designated
1 through 8.
¹
3280 or 3281 — If
six Token-Ring (FC 3280) and Ethernet (FC 3281) adapters
are installed in any combination, no other adapters can be installed.
¹
3280 or 3281 — If a combination of
five 3280 and 3281 adapters is to be
installed, then two other adapters can also be installed.
¹
The multiaccess enclosure supports a maximum of:
–
Four channel adapters, which can be Parallel Channel Adapters (FC 3299)
in any combination with ESCON adapters (FC 3287)
–
Two ATM adapters (FC 3284, 3293, 3294, or 3295)
Note: This adapter is also used for fast token-ring (FasTR)
–
One 4-port ISDN PRI/Channelized (T1/J1 interface) adapter (FC 3297)
One 4-port ISDN PRI/Channelized T1 Daughter card (FC 3251) can be
added to the base 4-port ISDN PRI/Channelized T1/J1 adapter (which
produces a total of 8 ports on a single adapter).
–
One 4-port ISDN PRI/Channelized (E1 interface) adapter (FC 3298)
One 4-port ISDN PRI/Channelized E1 Daughter card (FC 3252) can be
added to the base 4-port ISDN PRI/Channelized E1 adapter (which
produces a total of 8 ports on a single adapter).
–
Four ISDN adapters (FC 3283 or FC 3292)
A maximum of 8 ISDN interfaces are allowed. Four can be FC 3283 or
3292.
Note: You can configure a multiaccess enclosure with as many high-speed
adapters (FDDI FC 3286, 10/100-Mbps Ethernet FC 3288, and HSSI FC
3289) as desired; however, you may not be able to achieve full media
throughput concurrently on all the adapters. When planning for
installation, review system performance expectations with an IBM
representative.
Adapters can be installed in any of the eight adapter slots with the following
restrictions:
1. If the 2-port Token-Ring (FC 3280) or 2-port Ethernet (FC 3281) adapter is
plugged into slot 3 and active, then slot 4 cannot be used.
