7.1.2 Expanded XDM-100 Shelf with I/O Protection
A TPU shelf can be mounted on top of the XDM-100 basic shelf to add protection of
electrical I/O modules.
The TPU is a single-shelf cage with slots for the Tributary Protection Modules
(TPMs) and Tributary Control (TC) or Tributary Control and Fans (TCF) modules.
The modules are distributed as follows:
♦
Four (4) slots flexibly allocated for TPMs (single-slot or double-slot modules
are supported)
♦
One (1) slot allocated for the TC or TCF module
Each TPM is connected to the operating and protection modules of the XDM-100
shelf respectively. If a failure is detected in one of the operating I/O modules, the
XDM-100 control system sends control signals to the appropriate TPM relays to
switch traffic from the operating I/O module to the protection module. Several types
of TPM modules for 1:1 or 1:3 protection schemes are supported.
The TC or TCF is connected to the DC and control buses of the MXC cards via the
TPU backplane. It controls the switching of traffic from the main to protection I/O
module by relays in the corresponding TPM. In addition, the TCF has four fans that
provide cooling air to the modules installed in the TPU (optional).
The TPU is a 231 mm deep, 443 mm wide, and 75 mm high unit. It connects to a
connector on top of the XDM-100 shelf that provides the power and control buses
required for its operation. When the TPU is not installed, a protection cap covers this
connector.
