Outlet power for the extension cord
Each ESS model E10, F10, E20, or F20 includes a 4.7-m (14-ft), multiple-outlet
extension cord. Service personnel use the outlets within the ESS to power service
tools.
You must supply an appropriate receptacle for the extension cord at your site for
each ESS model. The ESS supports various power cable plugs to accommodate
your site. The outlet circuit should support at least 1200 W.
Remote service connection
You need to connect each ESS to a modem and a remote support switch. With the
remote support switch, you can attach up to seven ESSs. The modem connection
and the switch connection allow service personnel to perform service remotely. See
"Remote support features" on page 26 for information on remote support feature
codes.
Locate and provide power to the remote support switch and modem externally from
the ESS. The cable from the ESS to the remote support switch is 16 m (50 ft) long.
The cable from the remote support switch to the modem is 3.33 m (10 ft) long. You
supply the cable to connect the modem to a telephone jack.
Select the appropriate power cables for the modem and for the remote support
switch. Make your selection based on the feature code for the remote
support-switch power cable.
The modems that IBM offers are for worldwide use, and they meet all required
standards.
Connect the remote support switch to the serial port of each cluster in the ESS.
Remote service outlet power
You supply an appropriate receptacle for each modem and each remote support
switch. The ESS supports various power cable plugs to accommodate different
geographies. The country code determines which plug IBM supplies with the
product.
Remote power control
The ESS supports up to eight S/360 remote power-control interfaces to allow
remote power control.
Remote service telephone lines
You need one or more analog telephone lines to support remote service. Determine
the number of telephone lines you need by the number of ESSs you are installing.
You also provide the telephone cable that connects the modem to the
telephone-line jack. An expander supports one telephone line.
