Installing a TX Matrix TX-SIB

CAUTION: While you install the TX Matrix router or replace a fiber-optic array
cable, small deposits of oil, dust, and debris can enter the TX-SIB and
T640-SIB fiber-optic array adapters, the fiber-optic array cable connectors,
and the loopback connectors and adapters. We recommend that you clean
the optics in these components, as well as the loopback connector and
adapter dust covers, immediately before connecting them. For cleaning
instructions, see "Cleaning the TX Matrix and T640 Fiber-Optic Components
Overview" on page 200.
To install a TX-SIB into the rear of the chassis (see Figure 116 on page 261):
CAUTION: Be prepared to support the weight of the TX-SIB (approximately
35 lb [15.9 kg]) before you lift it.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
1.
the strap to an approved site ESD grounding point. See the instructions for your site.
Place one hand under the bottom edge of the TX-SIB and one hand around the top
2.
of the TX-SIB faceplate.
CAUTION: When the TX-SIB is out of the chassis, do not hold it by its
ejector handles or edge connectors. They cannot support its weight.
Locate the slot in the TX-SIB card cage in which you plan to install the TX-SIB.
3.
Lift the TX-SIB into place and carefully align first the bottom, then the top of the
4.
TX-SIB with the guides inside the card cage.
Carefully slide the TX-SIB all the way into the card cage until you feel resistance.
5.
Starting with the ejector handles on the top and bottom of the TX-SIB faceplate nearly
6.
horizontal, simultaneously turn both ejector handles clockwise to seat the TX-SIB.
If applicable, remove the protective tape covering each TX-SIB fiber-optic array adapter
7.
you are connecting to a T640-SIB.
Remove the dust covers from the fiber-optic array cable connectors. Loosen the
8.
thumbscrew and captive screw on each connector. (Use the supplied small slotted
screwdriver to loosen the captive screw.) Store the dust covers in a dust-free resealable
plastic bag.
If you removed the fiber-optic array cables from the comb panel assembly, reinstall
9.
them in the assembly as described in "Routing the TX Matrix Fiber-Optic Array Cables"
on page 111.
Install each cable connector (up to four) in its corresponding TX-SIB adapter. Align
10.
the connector with its corresponding TX-SIB adapter and carefully press it into the
