Plugging in an HSS cable.
Repeat this step for every HSS cable to be plugged in.
Note:
Make sure that all the cables are correctly labeled at both
ends before doing this step.
If you connect the HSS to a DTE equipment (such as IBM
2210 router), for allowing RLSD signal propagation, the DCE
side of the cable must be connected to the HSS and the
DCE side to the router.
a. Refer to the figure of the Step 2 on page 1-13.
b. Locate the cable with a label that matches its port number.
c. Take the plug of one cable, squeeze the side levers, and push the
plug strongly into the corresponding port in your unit.

Upgrade CDF
You must perform the Upgrade procedure in "Upgrading or Updating
CDF" on page 5-7. You can either do it now and continue with the next
step or later when you have finished all your connection procedures.

Activating the lines
Ask the host operator to activate any lines plugged in.
Notes:
a. The line number is the same as the port number.
b. If you have installed a link-attached 3745, make sure that the link
IPL port cables are connected before attempting an IPL.
