Hardware Overview, Nimbra 300 Series
The elements in the Nimbra 300 switch series have a common chassis
88x445x240 mm (HxWxD), with slots for two plug-in modules. One fixed
Gigabit Ethernet connection and power and grounding connections have similar
front placements in all 300 series switches. Data network connections (one
Ethernet and one serial RJ-45 connector) are common for all switches, but their
placement is to the right in 340/340-HD and to the left in 360.
Nimbra 340-HD is similar to Nimbra 340, apart from different front text as the
ASI ports are substituted with HD-SDI ports. Internally, 340-HD handles HD-
SDI signals and 340 ASI signals.
Nimbra 360 has no fixed ASI/HD-SDI ports and no fixed alarm port but four
fixed trunk ports and four time transfer 50 Ohm, BNC ports.
Figure 1. Nimbra 340
The Nimbra 340 switch with one fixed Gigabit Ethernet Access port and 2 fixed
ASI ports (each consisting of one IN, one OUT and one Monitor interface) is
illustrated above. In the Nimbra 340-HD, the ASI ports are used as HD-SDI
ports.
Figure 2. Nimbra 360
Nimbra 360 does not have fixed ASI or HD-SDI ports. Instead, it has four trunk
ports. They can be fitted with OC-3/STM-1, OC-12/STM-4 or OC-48/STM-16
transceivers. In the last case, only two ports can be used.
The main board of the 300 series switch is housed in a standard 2U
compartment, which also contains cooling fans and a card rack for two plug-in
modules. There are two slots for plug-in modules, numbered 1 and 2. The top
slot is number 1 and the bottom one is 2.
All connections to external equipment are made on the front of the switch.
There is a wide selection of optional plug-in modules. These modules are
secured at both ends with locks. The locks also makes it easier to insert and
remove modules (see chapter Hardware Maintenance.)
