Appendix A. Product specifications
This appendix contains the 2109 Model C36 with Model M12 specifications.
2109 Model M12 components
The 2109 Model M12 contains the following components:
v
A 14U chassis, designed to be mounted in a 48.26 cm (19 in.) rack. Two 2109
Model M12 switches can be mounted in a 2109 Model C36 cabinet.
v
16-port cards in configurations up to eight cards per chassis, with 16 optical ports
per card, compatible with SFPs.
v
Two CP cards, each with:
– One modem serial port with a DB-9 connector (full RS-232)
– One terminal serial port with a DB-9 connector (RS-232 signal subset)
– One IEEE compliant RJ-45 connector for use with a 10 Mbps or 100 Mbps
Ethernet connection
– A real-time clock (RTC) with a 10-year battery and 56 bytes of NVRAM
v
Four power supplies with built-in fans. The power supplies plug into internal
blind-mate connectors when installed in the chassis.
v
Two ac power inlet connectors with ac power switches (power panel).
v
A WWN card and bezel.
v
Three blower assemblies for forced-air cooling of the 16-port cards and the CP
cards.
Air enters inlet vents on the blower assembly side of the chassis and exits through
vents on the port side of the chassis. The blower speed is governed by inlet air
temperature. The blowers go into high speed when the inlet air temperature
exceeds 33°C (91°F).
