On the Cisco 7603 router, Cisco 7603-S router, Cisco 7604 router, Cisco 7606 router, Cisco 7606-S
router, and Cisco 7613 router, two threaded M4 holes are provided on the chassis frame to attach the
ground cable. (See
Figure 3-21
for the Cisco 7603 router and Cisco 7606 router,
Figure 3-22
for the
Cisco 7604 router,
Figure 3-23
for the Cisco 7606-S router, and
Figure 3-24
for the Cisco 7613 router.)
On the Cisco 7609 router and Cisco 7609-S router, three threaded M4 holes are provided on each side
of the chassis frame to attach the ground cable. Use any set of two M4 holes to install the ground cable
horizontally or vertically. (See
Figure 3-25
.)
Required Tools and Equipment
To connect the system ground, you need the following tools and materials:
•
One grounding lug.
•
Two M4 (metric) hex-head screws with locking washers.
Note
The grounding lug and M4 hex-head screws with locking washers are provided in kit
69-0815-01.
Note
The Cisco 7609-S router uses the 4AWG grounding lug and M6 hex-head screws with locking
washers provided in kit 69-1713-02.
•
One grounding wire. The grounding wire must be sized according to local and national installation
requirements. Depending on the power supply and system, a 12 AWG conductor or larger size wire
is required for U.S. installations.
•
Number 2 Phillips-head screwdriver.
•
Crimping tool (must be large enough to accommodate the girth of the grounding lug when crimping
the grounding cable into the lug).
•
Wire-stripping tool.
