connector on either
the front of the CMM or SMM module. This bracket can either be installed in front of a
CHP-CHASSIS-19, CHP-CHASSIS-19S, CHP-CHASSIS-19Q. or CHP-CHASSIS-19U chassis
without the handle kit (P/N CHP-HANDLE-KIT) installed or any place in the rack with 2RU (3.5
inches) of free space. The bracket is designed to only hold an HP-Compaq tablet PC model
TC1100 and this tablet PC should have the following peripherals:
■
CD-ROM drive capability to load the CMM software and firmware files
■
USB serial cable (P/N CHP-RS232-USB) for communications between the tablet PC
(type A male) and CMM/SMM (DB9 male).
Refer to the paragraph To install the chassis to install the tablet PC bracket assembly.
CHP Chassis Installation
The chassis is designed to be installed into a standard EIA 19 inch (48.26cm) rack. Refer to
Figure 2.6 as required. Mount the chassis into the rack in an indoor environment following
these guidelines:
■
Do not block the front or back panel of any chassis.
■
Maintain sufficient space in front of and behind the rack for air circulation.
■
No space is required between CHP chassis in the rack.
➤
To install the chassis
1. Refer to the system/headend map for the rack location of the CHP chassis.
2. Align the mounting holes in each of the front flanges of the chassis with holes in the
rack.
CAUTION Some components are sensitive to electrostatic discharge (ESD)! Use a
grounding strap to prevent damage to electronic components by accidental ESD. Do
not touch any components not specifically referred to in these instructions.
CAUTION Two people are required to install the chassis. Due to the weight of a
loaded chassis, the chassis should be installed without modules. To prevent the rack
from toppling, install these chassis starting at the bottom of the rack and finishing
at the top.
Note See Thermal Limits for Chassis Loading on page 2-13, for more information.
WARNING Install chassis from the bottom of the rack toward the top of the rack to
prevent the rack from toppling.
