Note The Cisco 7507 or Cisco 7507-MX installation must comply with all applicable codes and is approved
for use with copper conductors only. The ground bond fastening hardware should be of compatible
material and preclude loosening, deterioration, and electrochemical corrosion of hardware and joined
material. Attachment of the chassis ground to the central office or other interior ground system should
be made with a 6-AWG, copper ground conductor at a minimum. The Cisco 7507 and Cisco 7507-MX
chassis employ two threaded M5 chassis grounding receptacles, which are intended to be bonded directly
to the central office or other interior ground system. These receptacles are located on the rear of the
chassis. The chassis ground requires M5 screws and locking hardware, which are not included. (To
properly ground the chassis, see the
page 3-2.)

Remove a module as follows:
1. Use a screwdriver to loosen the captive installation
screws (shown in A).
2. Pull the ejector levers out to release the module from the
backplane connector (shown in B). The levers should snap
into their spring retainers.
3. Grasp the module handle with one hand and place your
other hand under the carrier to support and guide the
module as you pull it out of the slot. Avoid touching the card.
4. Place the removed module in the board racks that were
provided with your packing material.
5. Install a new module or a filler (MAS-7KBLANK or MAS-
RSPBLANK) to keep dust out of the chassis and to maintain
proper airflow through the chassis.
Install a module as follows:
1. Choose a slot for the new module and ensure that there is
enough clearance to accommodate any interface equipment
that you will connect directly to its ports.
2. Use a screwdriver to loosen the captive installation screws
(shown in A) and remove the filler (or the existing module)
from the slot to be filled.
3. Hold the module handle with one hand, and place your
other hand under the carrier to support the module and guide
it into the slot. Avoid touching the card.
4. Place the back of the module in the slot and align the guide
on the carrier with the groove in the slot (shown in A).
5. Carefully slide the module into the slot until the faceplate
makes contact with the ejector levers (shown in C).
6. Use the thumb and forefinger of each hand to push the
top lever down and the bottom lever up to fully seat the
module in the backplane connector (shown in B).
7. Use a screwdriver to tighten the captive installation screws.
