Telecommunications Requirements
The telecommunications requirements might be relevant to a private network connected to the public,
switched networks in some international service areas.
• The following port types on the IGX node are approved to carry public-switched, non-voice traffic
(OTR001, issue 3, port types 2DN):
– BC-E1 ports (G.703 2048 KBps).
– SDI-EIA/TIA-232, LDI-EIA/TIA-232, BC-SR, SDI-EIA/TIA-449, FRI-V.35 (approved for
direct connection to V.35 leased digital circuit).
– SDI-EIA/TIA-449 (when connected using Cisco EIA/TIA449/X.21 interface cable).
• The following port type on the IGX node is approved to carry PSTN digitized voice traffic:
– BC-E1 ports (G.703 2048 Kbps, when connected to a CVM or NTM front card).
Warning To prevent accidental discharge in the event of a power line cross, route on-premise wiring away
from power cables and off-premise wiring, or use a grounded shield to separate the on-premise
wiring from the power cables and off-premise wiring. A power line cross is an event, such as a
lightning strike, that causes a power surge. Off-premise wiring is designed to withstand power line
crosses. On-premise wiring is protected from power line crosses by a device that provides
overcurrent and overvoltage protection. Nevertheless, if the on-premise wiring is in close proximity
to, or not shielded from, the off-premise wiring or power cables during a lightning strike or power
surge, the on-premise wiring can carry a dangerous discharge to the attached interface, equipment,
and nearby personnel. To see translations of this warning, refer to the Regulatory Compliance and
Safety Information document that accompanied this product.
Note Cables must be attached so that their securing bolts are tightened such that a screwdriver is needed for
removal.
Seismic Anchoring for the Cisco Rack
This section describes installing the Cisco cabinet with the optional stability plate for seismic anchoring.
If the stability plate is not present, go to either the “IGX 8410 Enclosure Installation” section on
page 2-14 or the “IGX 8420 or IGX 8430 Enclosure Installation” section on page 2-18.
To set up the Cisco cabinet with the stability plate:
Step 1 Use the dimensions in Figure 2-1 to drill the holes for installing the stability plate.
