The following sections detail the installation procedures for a subtended network configuration.
Before you install the Cisco 6100 chassis with a subtended configuration, install and cable the system with a DOH configuration. Use the procedures in "Installing a Digital Off-Hook Configuration."
Complete the following steps to install the DS3 subtending I/O card on the Cisco 6100 backplane:
|
Note Screws for mounting the DS3 subtending I/O card are already on the backplane. The standoff screws are shipped with the card. |
|
Caution Proper ESD protection is required each time you handle Cisco DSLAM equipment. Installation and maintenance personnel should be properly grounded using ground straps to eliminate the risk of ESD damage to the equipment. Modules are subject to ESD damage each time they are removed from the chassis. |
Figure 4-1 shows Steps 1 through 4.
Step 2 Use a one-quarter inch socket driver or wrench to screw two standoff screws into the locations formerly occupied by the two screws that you removed in Step 1. Tighten the standoff screws using the one-quarter inch socket driver or wrench.
|
Caution Be careful when you remove the standoff screws and reinsert the screws into the screw holes on the backplane so that the backplane circuitry does not become damaged. |
Step 3 Position and align the holes on the DS3 subtending I/O card over the two standoff screws and gently press the DS3 subtending I/O card into the Cisco 6100 connector J48 on the subtending host chassis backplane.
Step 4 Use a one-quarter inch socket driver or wrench to screw two additional standoff screws into the screw holes in the DS3 subtending I/O card and into the original standoff screws added in Step 2. Tighten the standoff screws using the one-quarter inch socket driver or wrench.
Complete the following steps to cable the system I/O card to the DS3 subtending I/O card:
Step 3 Attach a ferrite as close as possible to the remaining end of the cable (see Figure 4-3 or Figure 4-4 for ferrite installation). Tie wrap the cable directly behind the ferrite, as necessary.
Step 6 Attach the ferrite as close as possible to the receive DS3 BNC connector (RX1) on the DS3 subtending I/O card (see Figure 4-3 or Figure 4-4 for ferrite installation). Tie wrap the cable directly behind the ferrite, as necessary.
Step 7 Attach a ferrite as close as possible to the remaining end of the cable (see Figure 4-3 or Figure 4-4 for ferrite installation). Tie wrap the cable directly behind the ferrite, as necessary.
Step 9 Tie wrap the transmit and receive cables coming from the DS3 subtending I/O card where the cables meet after coming from the ferrites and every 1 foot thereafter for a total of 15 feet, as shown in Figure 4-5.
Step 10 Tie wrap the transmit and receive cables coming from the system I/O card where the cables meet after coming from the ferrites and every 1 foot thereafter for a total of 15 feet, as shown in Figure 4-6.
|
Note If you have one subtending host chassis with two subtended node chassis, the second subtended node chassis connects to the TX2 and RX2 DS3 BNC connectors on the DS3 subtending I/O card. |
Step 11 Install the plastic ESD shield over the DS3 subtending I/O card using the following steps:
a. Position the holes in the plastic ESD shield over the existing standoff screws installed on the DS3 subtending I/O card.
b. Use a Phillips-head screwdriver and the backplane screws that you removed in the "Install the DS3 Subtending I/O Card" section to attach the plastic ESD shield to the DS3 subtending I/O card (see Figure 4-7).
Step 12 Repeat Steps 1 through 11 for each subtending host chassis to subtended node chassis connection.
Complete the following steps to install the optional rear cover:
Three screws are located on the right of the chassis, and three are located on the left. See Figure 4-8 for the location of the screws. Keep the backplane screws. They will be used when you install the cover-mounting brackets.
Step 2 Install the six standoff screws in the locations formerly occupied by the six screws that you removed in Step 1. Use a one-quarter inch socket driver or wrench to tighten the standoff screws.
Step 3 Face the rear of the chassis and install the cover-mounting bracket on the right side of the chassis. Place the bracket over the standoff screws. Use three of the screws that you removed in Step 1 to fasten the cover-mounting bracket to the chassis. (See Figure 4-9.)
Step 4 Install the cover-mounting bracket (with the rear cover attached) on the left side of the chassis. Place the bracket (with rear cover) over the standoff screws. Use three of the screws that you removed in Step 1 to fasten the cover-mounting bracket (with rear cover) to the chassis.
Step 5 Use the tie wraps provided in the accessory kit to attach cables to the cover-mounting bracket loops, as necessary.
Complete the following steps to apply power to the Cisco 6100 with NI-1 system:
Step 2 Apply power to the system with one of the following methods:
|
Caution If the power connections are improperly connected and power is applied while the modules are installed, the modules and chassis could be damaged. |
Step 3 Verify that the power connections from the Cisco 6100 and Cisco 6110 to the fuse and alarm panel are wired as shown in "Installing a Digital Off-Hook Configuration."
Step 4 Check the polarity of the -48 VDC connections to each chassis by attaching a voltmeter with the minus lead on -48RTN and the plus lead on -48V_A. Ensure that the meter reads between -36 VDC and -60 VDC. If your voltmeter shows a positive voltage, the power inputs might be reversed. If the voltmeter shows a negative voltage that is out of the -36 VDC to -60 VDC range, check the power supply for failure or check for a blown fuse in the fuse and alarm panel.
