Hardware Installation Installing the Hardware
To install a PHY card into an ATM line card:
1.
Use a Phillips screwdriver to loosen the two captive screws that hold the option slot cover in place.
2.
Save the option slot cover.
3.
Hold the PHY card by the edges and position it so that it is parallel with the slot opening.
4.
Insert the PHY card through the opening in the system unit by aligning the sides of the PHY card
with the card guide.
5.
Push the PHY card into the slot until the 96-pin connector is firmly seated on the motherboard.
6.
Fasten the PHY card to the system unit with the two captive screws and torque to 5 in-lb (0.56 N-m).
3.3.5 Multi-rate WAN Line Card and WICs
This section describes the procedure for installing the Multi-rate WAN line-card. Additionally, if your configuration
uses either a Clear Channel T3 or E3 WIC, you must consider the setting of the WIC module’s grounding-jumpers.
Setting Jumpers on the Clear Channel T3/E3 WICs
Both the Clear Channel T3 and E3 WICs contain a set of jumpers (JP2, JP3,and JP4). These jumpers allow you to set
whether the shielding of the transmit (Tx) and Receive (Rx) cables are grounded. In their default positions, the jumpers
are set such that the shielding on the Tx cable is grounded at the RS and the shielding on the Rx cable is not grounded
at the RS (see
Table 3-2 and Figure 3-10 ).
To Ground the Shielding on the Rx Cable – Remove the jumper block on JP4 and place it on the pins of JP3.
Note The industry standard for E3 is both Tx and Rx cable shielding grounded. To be
E3 industry-compliant, the jumper block must be moved from JP4 to Jp3.
To Remove Grounding of the Shielding on the Tx Cable
– Remove the jumper block on JP2.
Table 3-2 Jumper default settings
Jumper Default Position Setting
JP2 Jumper block in place Shielding on Tx cable is grounded at the RS
JP3 No jumper block in place (open) Shielding on Rx cable is not grounded at the RS
JP4 Jumper block in place Storage jumper for jumper block to be used on JP3
