Converting a processor port network to a port network (IP600)
104 Migrating to the Avaya S8700 or S8710 Media Server
June 2004
Powering down the control chassis
CAUTION:
Make sure you have done the premigration administration. See Preconversion
administration (R, SI, CSI) on page 78 if CSI or Preconversion administration (S8100) on
page 80 if S8100 Media Server.
1 Press and hold the shutdown button on the processor’s faceplate until the shutdown process starts.
Make sure you see the green light indicating the system has shut down before continuing.
!
DANGER:
The latch on the power supply acts as the DC power switch and only removes DC
power from the backplane, not the AC power. To remove the AC power from the
chassis, pull the AC power cord from the back of the chassis.
2 Power down the chassis by unplugging the power cord from the back of the chassis.
Replacing the WP cables
WP cables have straight, not twisted, wires. They may be mostly white with two red, or multi-colored.
You must replace the WP cables, which connect the backplane to the rear connector panel, with Twisted
Pair I/O cables. If the cables have multi-colored, tightly twisted wires, no replacement is necessary.
1 Loosen the thumb screws on the fan assembly and pull it straight out as shown in Figure 19, Fan
Assembly Removal, on page 105. Leave the fan assembly off until all the wires are installed.
2 Note the orientation of the existing 10 cables (WP-90753, LI). The WP cables may be white and
red or multicolored.
3 Remove the nontwisted pair WP cables from the backplane and the connector panel slots.
4 In their place install the 10 tight-twisted pair I/O cables (700181118) onto the backplane,
according to the proper orientation shown in Figure 20, Proper Orientation for the Twisted Pair
I/O Cables, on page 105. Observe the white outline printed on the backplane for the location of
each connector.
5 When viewed from the "wiring" side of the twin connectors (that is, while plugging them into the
backplane) and with the connectors oriented properly for plug-in, they should look like Figure 20,
Proper Orientation for the Twisted Pair I/O Cables, on page 105.
The circled pin locations are “No-Connects”; that is, they have no wires in them. At the top there
is an orange-black pair on the right and a violet-brown pair on the left.
The 50-position metal shell D connectors should be installed into the connector panel with the
longer side of the D (pins 1–25) toward the right when viewed from the rear of the media gateway.
6 Replace the fan unit if no other media gateways are to be installed. If you are adding more media
gateways to the rack, leave the fan units off until all the TDM cables are installed.
