You must leave at least 24 in. (61 cm) both in front of and behind the PTX1000 for
service personnel to remove and install hardware components, you must leave adequate
space at the front and back of the PTX1000. NEBS GR-63 recommends that you allow
at least 30 in. (76.2 cm) in front of the rack or cabinet and 24 in. (61 cm) behind the
rack.
Table 19 on page 50 lists the physical specifications for the PTX1000 chassis.

Table 20 on page 50 describes the factors you must consider while planning the electrical
wiring at your site.
WARNING: It is particularly important to provide a properly grounded and
shielded environment and to use electrical surge-suppression devices.
Guidelines
If your site experiences any of the following problems, consult experts in electrical surge
suppression and shielding:
Improperly installed wires cause radio frequency interference (RFI).
Damage from lightning strikes occurs when wires exceed recommended distances or pass
between buildings.
Electromagnetic pulses (EMPs) caused by lightning damage unshielded conductors and
electronic devices.
To reduce or eliminate RFI from your site wiring, do the following:
Use a twisted-pair cable with a good distribution of grounding conductors.
If you must exceed the recommended distances, use a high-quality twisted-pair cable with
one ground conductor for each data signal when applicable.
